Functional DescriptionFigure4.Si4844-B Functional Block Diagram4.1. OverviewThe Si4844-B is the analog-tuned digital-display digital CMOS AM/FM/SW radio receiver IC that integrates the complete receiver function from antenna input to audio output. Working with an external MCU with LCD/LED driver, Si4844-B can output the AM/FM/SW frequencies, band, Bass/Treble and stereo/mono information to display on LCD/LED, while using a simple potentiometer at the front end for analog-tune. Leveraging Skyworks' proven and patented digital low intermediate frequency (low-IF) receiver architecture, the Si4844-B delivers superior RF performance and interference rejection in AM, FM and SW bands. The Si4844-B is pin-to-pin compatible with the current Si484x-A tuning. The Si4844-B shares the advanced features of the Si484x-A and can support a wider range of FM and SW bands. It also supports China TV channels and audio reception in the FM band. The superior control algorithm integrated in Si4844-B provides an easy and reliable control interface while eliminating all the manually tuned external components used in traditional solutions.Like other successful audio products from Skyworks, Si4844-B offers unmatched integration and PCB space savings with minimum external components and small board area on a single side PCB. The high integration and complete system production test simplifies design-in, increases system quality, and improves manufacturability. The receiver has very low power consumption, runs off two AAA batteries, and delivers the performance benefits of high performance digital radio experience with digital display to the legacy analog-tuned radio market.The Si4844-B provides good flexibility in using the chip. The frequency range of FM/AM/SW bands, mono/stereo threshold, de-emphasis value, AM tuning step, AM soft mute level/rate, and Bass/Treble can be either configured by the MCU or by using external hardware to make a selection. The reference clock of the FM tuner can be provided either by the crystal or by the host MCU within tolerance.Si4844-B also has flexibility in selecting bands and configuring band properties, enabling masked Host MCU for multiple projects, and reducing the cost of development. Four tuning preferences are available tomeet different tuning preference requirements.4.2. FM ReceiverThe Si4844-B integrates a low noise amplifier(LNA) supporting the worldwide FM broadcast band (64to 109MHz) and the TV audio stations within the fre quency range in China are also supported. The FM band can also be configured to be a wider range such as 64–108 MHz in one band.Pre-emphasis and de-emphasis is a technique used by FM broadcasters to improve the signal-to-noise ratio of FM receivers by reducing the effects of high frequency interference and noise. When the FM signal is transmitted, a pre-emphasis filter is applied to accentuate the high audio frequencies. All FM receivers incorporate a de-emphasis filter which attenuates high frequencies to restore a flat frequency response. Two time constants are used in various regions. The de-emphasis time constant can be chosen to be 50 or 75μs. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines.”The Si4844-B also has advanced stereo blending that employs adaptive noise suppression. As a signal quality degrades, the Si4844-B gradually combines the stereo left and right audio channels to a mono audio signal to maintain optimum sound fidelity under varying reception conditions. The Si4844-B can output a stereo signal to MCU with LCD/LED driver to display on the LCD/LED so that the user can easily discern the signal quality.The stereo on signal is defined using both RSSI and the Left and Right separation levels as these two specifications are the primary factors for stereo listening. The criteria can be set between two conditions: the Left and Right channels are separated by more than 6dB with RSSI at >20dB or Left and Right channels are separated by more than 12dB with RSSI at >28dB. The selection can be set up using different values of the external resistor or configured by the host MCU. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines.”The user can also refer to the “AN610: Si48xx ATDD Programming Guide” for those who want to configure the value by host MCU.4.3. AM ReceiverThe highly integrated Si4844-B supports worldwide AM band reception from 504 to 1750kHz with five sub-bands using a digital low-IF architecture with a minimum number of external components and no manual alignment required. This patented architecture allows for high-precision filtering, offering excellent selectivity and SNR with minimum variation across the AM band. Similar to the FM receiver, the Si4844-B optimizes sensitivity and rejection of strong interferers, allowing better reception of weak stations.To offer maximum flexibility, the receiver supports a wide range of ferrite loop sticks from 180–450μH. An air loop antenna is supported by using a transformer to increase the effective inductance from the air loop. Using a 1:5 turn ratio inductor, the inductance is increased by 25 times and easily supports all typical AM air loop antennas, which generally vary between 10 and 20μH.A 9, 10kHz tuning step can be chosen by the external resistor or host MCU according to the different regions, and AM soft mute level can be programmed by the host MCU to have different tuning experiences. One of the AM bands can be configured as a universal AM band that simultaneously supports 9kHz and 10kHz channel spaces for all regional AM standards worldwide. Refer to “AN610: Si48xx ATDD Programming Guide” and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for more details.4.4. SW ReceiverThe Si4844-B supports short wave band receptions from 2.3 to 28.5MHz in 5kHz step size increments. It can also be configured to have a wide SW band that can be used in SW radio with 1 or 2 SW banks. Si4844-B supports extensive short wave features such as minimal discrete components and no factory adjustments. The Si4844 supports using the FM antenna to capture short wave signals. Refer to “AN610: Si48xx ATDD Programming Guide”and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for more details.4.5. Frequency TuningA valid channel can be found by tuning the potentiometer that is connected to the TUNE1 and TUNE2 pin of the Si4844-B chip.To offer easy tuning, the Si4844-B also outputs the tuned information to the MCU with LCD/LED driver to display. It will light up the icon on display if the RF signal quality passes a certain threshold when tuned to a valid station. Multiple tuning preferences are available. The user can choose to have the best performance (volume, stereo/mono effect) only at the exact channel, or the best performance in a larger range. Refer to "AN610: Si48xx ATDD Programming Guide" for more details. 4.6. Band SelectThe Si4844-B supports worldwide AM band with five sub-bands, US/Europe/Japan/China FM band with five sub-bands, and SW band with 16 sub-bands. Si4844-B provides the flexibility to configure the band and band properties at either the MCU side or the Tuner side, enabling masked MCU for multiple projects. For details on band selection, refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”and "AN610: Si48xx ATDD Programming Guide".4.7. Bass and TrebleThe Si4844-B further supports Bass/Treble tone control for superior sound quality. The Si4844-B can be set to be default normal, or programmed by the host MCU I2C-compatible 2-wire mode. FM has nine levels Bass/Treble effect and AM/SW has seven levels Bass/Treble effect. For further configuration details, refer to "AN610: Si48xx ATDD Programming Guide." 4.8. Volume ControlThe Si4844-B not only allows users to use the traditional PVR wheel volume control through an external speaker amplifier, it also supports digital volume control programmed by the host MCU. Si4844-B can be programmed to be Bass/Treble mode only or digital volume mode only; it can also be programmed to have the digital volume coexist with Bass/Treble in two modes. Refer to "AN610: Si48xx ATDD Programming Guide" and “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines” for more details.4.9. Stereo Audio ProcessingThe output of the FM demodulator is a stereo multiplexed (MPX) signal. The MPX standard was developed in 1961, and is used worldwide. Today's MPX signal format consists of left + right (L+R) audio, left – right (L–R) audio, a 19kHz pilot tone.Figure5.MPX Signal Spectrum4.9.1. Stereo DecoderThe Si4844-B's integrated stereo decoder automatically decodes the MPX signal using DSP techniques. The 0 to 15kHz (L+R) signal is the mono output of the FM tuner. Stereo is generated from the (L+R), (L–R), and a 19kHz pilot tone. The pilot tone is used as a reference to recover the (L–R) signal. Output left and right channels are obtained by adding and subtracting the (L+R) and (L–R) signals respectively.4.9.2. Stereo-Mono BlendingAdaptive noise suppression is employed to gradually combine the stereo left and right audio channels to a mono (L+R) audio signal as the signal quality degrades to maintain optimum sound fidelity under varying reception conditions. Three metrics, received signal strength indicator (RSSI), signal-to-noise ratio (SNR), and multipath interference, are monitored simultaneously in forcing a blend from stereo to mono. The metric which reflects the minimum signal quality takes precedence and the signal is blended appropriately.All three metrics have programmable stereo/mono thresholds and attack/release rates. If a metric falls below its mono threshold, the signal is blended from stereo to full mono. If all metrics are above their respective stereo thresholds, then no action is taken to blend the signal. If a metric falls between its mono and stereo thresholds, then the signal is blended to the level proportional to the metric’s value between its mono and stereo thresholds, with an associated attack and release rate.0575338231915Frequency (kHz)ModulationLevel4.10. Stereo DACHigh-fidelity stereo digital-to-analog converters (DACs) drive analog audio signals onto the LOUT and ROUT pins. The audio output may be muted.4.11. Soft MuteThe soft mute feature is available to attenuate the audio outputs and minimize audible noise in very weak signal conditions. An advanced algorithm is implemented to get a better analog tuning experience. The soft mute feature is triggered by the SNR metric. The SNR threshold for activating soft mute is programmable, as are soft mute attenuation levels and attack and decay rates.4.12. Reference ClockThe Si4844-B supports programmable RCLK input (to XTALI pin) with the spec listed in Table7. It can be shared with the host MCU to save extra crystal.An onboard crystal oscillator is available to generate the 32.768kHz reference when an external crystal and load capacitors are provided. Refer to "AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines" for more details.4.13. Reset, Powerup, and Powerdown Setting the RSTB pin low will disable analog and digital circuitry, reset the registers to their default settings, and disable the bus. Setting the RSTB pin high will bring the device out of reset.Figure1 shows typical reset, startup, and shutdown timings for the Si4844-B. RSTB must be held low (asserted) during any power supply transitions and kept asserted as specified in Figure1 after the power supplies are ramped up and stable. Failure to assert RSTB as indicated here may cause the device to malfunction and may result in permanent device damage.A powerdown mode is available to reduce power consumption when the part is idle. Putting the device in powerdown mode will disable analog and digital circuitry while keeping the bus active.4.14. Memorizing StatusThe Si4844-B provides the feature to memorize status from the last power down with a simple design on PCB, including frequency of the FM/AM/SW station. Refer to “AN602: Si4822/26/27/40/44 Antenna, Schematic, Layout, and Design Guidelines”for details.4.15. Programming with CommandsTo ease development time and offer maximum customization, the Si4844-B provides a simple yet powerful software interface to program the receiver. The device is programmed using commands, arguments, properties, and responses.To perform an action, the user writes a command byte and associated arguments, causing the chip to execute the given command. Commands control an action such as powerup the device, shut down the device, or get the current tuned frequency. Arguments are specific to a given command and are used to modify the command. Properties are a special command argument used to modify the default chip operation and are generally configured immediately after powerup. Examples of properties are de-emphasis and soft mute attenuation threshold.Responses provide the user information and are echoed after a command and associated arguments are issued. All commands provide a 1-byte status update, indicating interrupt and clear-to-send status information. For a detailed description of the commands and properties for the Si4844-B, see "AN610: Si48xx ATDD Programming Guide."。

A T S 004406 R e v B 5/17DSP8807Self Contained, Compact Multi-Zone Digital Controlled Sound Masking ProcessorGeneral DescriptionThe Atlas Sound DSP8807 is a self-amplified, sound masking controller with extensive digital signal processing (DSP) and telephony interface capabilities. All aspects of signal routing, processing and prioritization are administered through an intuitive Graphic User Interface (GUI) managed via a local Windows ® based laptop or desktop computer. The software has the ability to expand up to (253) systems with over 2,000 zones (2,048) with primary and secondary assignment in a zone paging dialing plan. It also provides the ability to set up “All zone” page, “Group zone“ page (up to 32 groups) and “Single zone“ page with an architectural dialing plan (2-digit DTMF) set up in the GUI. AVB (Audio Video Bridge) audio networking allows distribution of paging, BGM and line level inputs between multiple DSP8807 and/or DSP2212 units across TCP/IP data networks.The DSP8807 has 8 channels of independent on-board digital class-D amplifiers capable of delivering 50W RMS per 70.7V output. Additionally, a simultaneous line level output rated at 1V/600Ω (nominal) per zone is available for driving higher power amplifiers. The DSP8807 includes two independent, uncorrelated pink noise generators, which are random and non-repeating up to 215 hours with 1⁄3-octave EQ adjustments programmable on a per zone basis.Each DSP8807 is capable of managing remote ambient level sensing microphones (ALM-1) for each zone (x8), via a single CAT5e cable up to 1,000 feet from the DSP8807. These microphones can provide automatic adjustment of the masking level based on real- time noise levels with set up and control via the GUI.Features• A VB (Audio Video Bridge) Audio Networking Allows Distribution of Paging, BGM and Line Level Inputs Between Multiple DSP8807 and/or DSP2212 Units Across TCP/IP Data Networks • User Friendly GUI and Easy Network Setup• Built-InAmplificationforEachOutput(***********)• Line Level Outputs (x8) for Expansion to External Amplifiers • Expandable - Up to 256 Units (2048 Zones) • Non Repeating Pink Noise Sources • Front Panel Visual Status LED’s for All I/O • Parametric EQ for All Paging / Line Sources • 1⁄3 Octave EQ for All Masking Zones• C omprehensive Telco Interface Facilitates Complex Paging Scenarios for Multi Floor Buildings • Paging Mic Input for Evacuation or General Announcements • Optional Ambient Sensing Microphones for Automatic System Adjustment •UL / CUL and FCC ListedDSP8807 FrontDSP8807 Back238751461.

The FM receiver is based on the architecture of KT Micro’s latest generation FM receiver chips in mass production. There are no external filters or frequency-tuning devices thanks to a proprietary digital low-IF architecture consisting of a fully-integrated LNA, an automatic gain control (AGC), a set of high-performance ADCs, high-quality analog and digital filters, and an on-chip low-noise self-tuning VCO. The on-chip high-fidelity Class-AB driver further eliminates the need for external audio amplifiers and can drive stereo headphones directly.4.3.AM ReceiverKT0933 enters AM mode by setting register AM_FM to 1. The AM Receiver employs a similar digital low IF architecture and share many circuits with the FM receiver. The minimum AM channel spacing can be set to 1KHz. The bandwidth of the channel filter can be set to 1KHz to 5KHz to suit various requirements.The AM receiver in KT0933 can provide accurate and automatic AM tuning without manual alignment. It supports ferrite loop antenna with value between 360uH and 620uH.4.4.Operation BandsKT0933 supports wide FM band and AM bands. The FM receiver covers frequencies from 32MHz to 110MHz. The AM band is from 500KHz to 1750KHz.4.5.StandbyTo enter standby mode, the STDBY register shall be set to 1 through I2C interface. To quit standby mode, STDBY should be set to 0.4.6.Crystal and reference clockKT0933 integrates a low frequency crystal oscillator that supports 32.768KHz or 38KHz crystals. Alternatively a CMOS level external reference clock may be used by setting the RCLK_EN register to 1 and setting FPFD<19:0> according to the frequency of the reference clock. The FPFD<19:0> is the frequency value in the unit of 1/16Hz. In order to illuminate the usage of these bits clearly some examples are given in Table 6.Table 6: Examples using different crystal or reference clockode, the audio volume is gradually attenuated when the signal reception is weak. (i.e. whe n the RSSI and SNR are below a certain level as defined by AM_SMUTE_START_RSS I<2:0> or AM_SMUTE_START_ SNR<2:0>, respectively.) The attenuation slope can be configured through AM_SMUTE_SLOPE_ RSSI<2:0> or AM_SMUTE_SLOPE_SNR< 2:0>, respectively.The maximum attenuation of volume is -21dB when RSSI is used as soft mute judgment threshold. The maximum attenuation of volume is -12dB when RSSI is used as soft mutejudgment threshold. The maximum total attenuation of volume can be configured through AM_SMUTE_MIN_GAIN<2:0>.MONO playback mode can be forced by setting the MONO to 1.4.7.4. BassKT0933 provides bass boost feature for audio enhancement. The gain of the bass boost can be programmed through BASS<1:0>. With BASS<1:0>=00, this feature is disabled.4.7.5. Stereo DAC, Audio Filter and DriverTwo high-quality audio digital-to-analog converters (DAC) are integrated along with high-fidelity analog audio filters and class AB drivers. Headphones with impedance as low as 16ohms can be direct driven without adding external audio drivers. An integrated anti-pop circuit suppresses the click-and-pop sound during power up and power down.In order to suit different applications, the gain of the audio driver can be adjusted through register bits FM_GAIN<2:0> , AM_GAIN<3:0>and AM_VOLUME<3:0>and to avoid the saturation in output stage, the common mode voltage can also be adjust according to different power supply voltage through register bits AUDV_DCLVL<2:0>.4.7.6. AM Channel Filter BandwidthKT0933 provides programmable AM channel bandwidth from 1KHz to 5KHz through FLT_SEL <2:0>.4.7.7. TuneThe fully integrated LO synthesizer supports wide band operation. Before tuning，the register of Channel should be written，and then write the register TUNE. Channel tuning is started when the register TUNE is set to 1.In FM mode, the channel frequency is set by FM_CHAN<11:0> and is defined asFreq(KHz) = 50KHz × FM_CHAN<11:0>In AM mode, the channel frequency is set by AM_CHAN<14:0> and is defined asFreq(KHz) = 1KHz × AM_CHAN<14:0>4.7.8. SEEKKT0933 offers effective software based seek algorithm. Refer to application notes for more information.4.8.I2C Control InterfaceWrite Operations:BYTE WRITE:The write operation is accomplished via a 3-byte sequence:Serial address with write commandRegister addressRegister dataA write operation requires an 8-bit register address following the device address word and acknowledgment. Upon receipt of this address, the KT0933 will again respond with a “0” and then clock in the 8-bit register data. Following receipt of the 8-bit register data, the KT0933 will output a “0” and the addressing device, such as a microcontroller, must terminate the write sequence with a stop condition (see Figure 4).Read Operations:RANDOM READ:The read operation is accomplished via a 4-byte sequence:CURRENT ADDRESS READ:last address accessed during the last read or write operation, incremented by one. This address stays valid between operations as long as the chip power is maintained.Once the device address with the read/write select bit set to “1” is clocked in and acknowledged by the KT0933, the current address data word is serially clocked out. The microcontroller does not respond with an input “0” but does generate a following stop condition (see Figure 5).CURRENT REGISTER READPROCEDUREFigure 5: Serial Interface ProtocolNote:The serial controller supports slave mode only. Any register can be addressed randomly.The address of the slave in the first 7 bits and the 8th bit tells whether the master is receiving data from the slave or transmitting data to the slave. The I2C write address is 0x6C and the read address is 0x6D.CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only during SCL low time periods (see Figure6). Data changes during SCL high periods will indicate a start or stop condition as defined below.START CONDITION: A high-to-low transition of SDA with SCL high is a start condition which must precede any other command (see Figure gure 7).STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence, the stop command will place the KT0933 in a standby power mode (see Figure 7).ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the KT0933 in 8-bit words. The KT0933 sends a “0” to acknowledge that it has received each word. This happens during the ninth clock cycle (see Figure 8).Figure 6: Clock and Data TransitionsFigure 7: Start and Stop DefinitionFigure 8: Acknowledge4.9.Register Bank4.9.1.
