MAX2820EVKIT中文资料

General DescriptionThe MAX2820/MAX2820A and MAX2821/MAX2821A single-chip zero-IF transceivers are designed for the 802.11b (11Mbps) applications operating in the 2.4G Hz to 2.5G Hz ISM band. The transceivers are nearly identical, except the MAX2821 and MAX2821A also provide a low-power shutdown mode and an ana-log voltage reference output. The MAX2820A/MAX2821A are cost-reduced versions, virtually identi-cal in pinout and performance to the MAX2820/MAX2821. The transceivers include all the circuitry required to implement an 802.11b RF-to-baseband transceiver solution, providing a fully integrated receive path, transmit path, VCO, frequency synthesis,and baseband/control interface. Only a PA, RF switch,RF BPF, and a small number of passive components are needed to form the complete radio front-end solution.The ICs eliminate the need for external IF and base-band filters by utilizing a direct-conversion radio archi-tecture and monolithic baseband filters for both receiver and transmitter. They are specifically opti-mized for 802.11b (11Mbps CCK) applications. The baseband filtering and Rx and Tx signal paths support the CCK modulation scheme for BER = 10-5 at the required sensitivity levels.The devices are suitable for the full range of 802.11b data rates (1Mbps, 2Mbps, 5.5Mbps, and 11Mbps) and also the higher-rate 22Mbps PBCC TM standard. The MAX2820 and MAX2821 are available in a 7mm ×7mm 48-lead QFN package. The MAX2820, MAX2821,MAX2820A, and MAX2821A are available in a 48-lead thin QFN package.Applications802.11b 11Mbps WLAN802.11b +22Mbps PBCC High-Data-Rate WLAN 802.11a + b Dual-Band WLAN 2.4GHz ISM Band RadiosFeatureso 2.4GHz to 2.5GHz ISM Band Operationo 802.11b (11Mbps CCK and 22Mbps PBCC) PHY Compatible o Complete RF-to-Baseband TransceiverDirect-Conversion Upconverters and DownconvertersMonolithic Low-Phase-Noise VCO Integrated Baseband Lowpass FiltersIntegrated PLL with 3-Wire Serial Interface Digital Bias Control for External PATransmit Power Control (Range > 25dB)Receive Baseband AGC (Range > 65dB)Complete Baseband Interface Digital Tx/Rx Mode ControlAnalog Receive Level Detection o -97dBm Rx Sensitivity at 1Mbps o -87dBm Rx Sensitivity at 11Mbps o +2dBm Transmit Power (11Mbps CCK)o Single +2.7V to +3.6V Supplyo Low-Current Shutdown Mode (MAX2821 only)o Very Small 48-Pin QFN Package(s)MAX2820/MAX2820A/MAX2821/MAX2821A2.4GHz 802.11b Zero-IF Transceivers________________________________________________________________Maxim Integrated Products 1Ordering Information19-2493; Rev 5; 5/05For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin Configuration/Functional Diagram and Typical Application Circuit appear at end of data sheet.PBCC is a trademark of Texas Instruments, Inc.M A X 2820/M A X 2820A /M A X 2821/M A X 2821A2.4GHz 802.11b Zero-IF TransceiversABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICS(MAX2820/MAX2821 EV kit: V CC = +2.7V to +3.6V, RF_GAIN = V IH , 0V ≤V TX_GC ≤+2.0V, 0V ≤V RX_AGC ≤+2.0V, RBIAS = 12k Ω, no input signals at RF and baseband inputs, all RF inputs and outputs terminated into 50Ω, receiver baseband outputs are open, trans-mitter baseband inputs biased at +1.2V, registers set to default power-up settings, T A = -40°C to +85°C, unless otherwise noted.Typical values are at V CC = +2.7V, T A = +25°C, unless otherwise noted.)

MICROWIRE is a trademark of National Semiconductor Corp.MAX2820/MAX2820A/MAX2821/MAX2821AM A X 2820/M A X 2820A /M A X 2821/M A X 2821APin Description (continued)Changes in “A” VersionThe MAX2820A/MAX2821A are cost-reduced versions of the original MAX2820/MAX2821, intended as a drop-in replacement —no changes to PC board layout, BOM,or control software are required. Functionally, the “A ”version removes unused functions and programmability while maintaining virtually identical performance char-acteristics. The changes are detailed below.SynthesizerThe original device has the ability to program the charge-pump source/sink current (±1mA or ±2mA); the “A ” version sets the charge-pump current at ±2mA, and bit SYNTH:D6 (ICP) should now always be pro-grammed to be 1.Receive FilterThe original device has the ability to control the base-band LPF corner; the “A ” version sets the LPF corner at 8.0MHz. Register bits RECEIVE:D2–D0 are now “don ’t cares.”Receive-Level Detector (RSSI)The original device has a receive-level detect output (pin 43, “RX_DET ”); the “A ” version removes this functionality.Pin 43 is a no-connect (N.C.) on the “A ” version.MAX2820/MAX2820A/MAX2821/MAX2821AOperating ModesThe MAX2820/MAX2821 have four primary modes of operation: shutdown, standby, receive active, and transmit active. The modes are controlled by the digital inputs SHDNB, TX_ON, and RX_ON. Table 1 shows the operating mode vs. the digital mode control input.Shutdown ModeShutdown mode is achieved by driving SHDNB low. In shutdown mode, all circuit blocks are powered down,except for the serial interface circuitry. While the device is in shutdown, the serial interface registers can still be loaded by applying V CC to the digital supply voltage (VCC_DIG). All previously programmed register values are preserved during the shutdown mode, as long as VCC_DIG is applied.Standby ModeStandby mode is achieved by driving SHDNB high and RX_ON and TX_ON low. In standby mode, the PLL,VCO, LO generator, LO buffer, LO quadrature, and fil-ter autotuner are powered on by default. The standby mode is intended to provide time for the slower-settling circuitry (PLL and autotuner) to turn on and settle to the correct frequency before making RX or TX active. The 3-wire serial interface is active and can load registervalues at any time. Refer to the serial-interface specifi-cation for details.Receive ModeReceive mode is enabled by driving the digital inputs SHDNB high, RX_ON high, and TX_ON low. In receive mode, all receive circuit blocks are powered on and all VCO, PLL, and autotuner circuits are powered on. None of the transmit path blocks are active in this mode. Although the receiver blocks turn on quickly, the DC offset nulling requires ~10µs to settle. The receiver signal path is ready ~10µs after a low-to-high transition on RX_ON.Transmit ModeTransmit mode is achieved by driving the digital inputs SHDNB high, RX_ON low, and TX_ON high. In transmit mode, all transmit circuit blocks are powered on and all VCO, PLL, and autotuner circuits are powered on.None of the receive path blocks is active in this mode.Although the transmitter blocks turn on quickly, the baseband DC offset calibration requires ~2.2µs to complete. In addition, the TX driver amplifier is ramped from the low-gain state (minimum RF output) to high-gain state (peak RF output) over the next 1µs to 2µs.The transmit signal path is ready ~4µs after a low-to-high transition on TX_ON.Figure 1. MAX2820/MAX2821 Serial-Interface Timing DiagramM A X 2820/M A X 2820A /M A X 2821/M A X 2821AProgrammable RegistersThe MAX2820/MAX2820A and MAX2821/MAX2821A (the MAX2820 family) contain programmable registers to control various modes of operation for the major cir-cuit blocks. The registers can be programmed through the 3-wire SPI/QSPI/MICROWIRE-compatible serial port. The MAX2820 family includes five programmable registers:1)Test register (always program as in Table 2).2)Block-enable register 3)Synthesizer register 4)Channel frequency register 5)Receiver settings register 6)Transmitter settings registerEach register consists of 16 bits. The four most signifi-cant bits (MSBs) are the register ’s address. The twelve least significant bits (LSBs) are used for register data.Table 2 summarizes the register configuration. A detailed description of each register is provided in Tables 3–6.Data is shifted in the MSB first. The data sent to the transceiver, in 16-bit words, is framed by CSB. When CSB is low, the clock is active and data is shifted with the rising edge of the clock. When CSB transitions to high, the shift register is latched into the register select-ed by the contents of the address bits. Only the last 16bits shifted into the device are retained in the shift reg-ister. No check is made on the number of clock pulses.Figure 1 documents the serial interface timing for the MAX2820 family.Power-Up Default StatesThe devices provide power-up loading of default states for each of the registers. The states are loaded on a VCC_DIG supply voltage transition from 0V to V CC . The default values are retained until reprogrammed through the serial interface or the power supply voltage is taken to 0V. The default state of each register is described in Table 3. Note:Putting the IC in shutdown mode does not change the contents of the programming registers.Block-Enable RegisterThe block-enable register permits individual control of the enable state for each major circuit block in the transceiver.The actual enable condition of the circuit block is a logical function of the block-enable bit setting and other control input states. Table 4 documents the logical definition of state for each major circuit block.Synthesizer RegisterThe synthesizer register (SYNTH) controls the reference frequency divider and charge-pump current of the PLL.See Table 5 for a description of the bit settings.Channel Frequency RegisterThe channel frequency register (CHANNEL) sets the RF carrier frequency for the radio. The channel is pro-grammed as a number from 0 to 99. The actual frequency is 2400 + channel in MHz. The default setting is 37 for 2437MHz. See Table 6 for a description of the bit settings.Receiver Settings Register (MAX2820/MAX2821 Only)The receive settings register (RECEIVE) controls the receive filter -3dB corner frequency, RX level detector midpoint, and VG A DC offset nulling parameters. The defaults are intended to provide proper operation.Table 2. Programming Register Definition Summary (Address and Data)MAX2820/MAX2820A/MAX2821/MAX2821ATable 4.

See Table 7 for a description of the bit settings.Transmitter Settings Register The transmitter settings register (TRANSMIT) controls the 4-bit PA bias DAC. The 4 bits correspond to a PA bias current between 0 and full scale (~300µA). See Table 8 for the bit settings.Applications InformationReceive PathLNA The RX_RF inputs are high-impedance RF differential inputs AC-coupled on-chip to the LNA. The LNA inputs require external impedance matching and differential to single-ended conversion. The balanced to single-ended conversion and interface to 50Ωis achieved through the use of an off-chip 2:1 balun transformer, such as the small surface-mount baluns offered by Murata and TOKO. In the case of the 2:1 balun, the RX RF input must be impedance-matched to a differen-tial/balanced impedance of 100Ω. A simple LC network is sufficient to impedance-match the LNA to the balun. The Typical Application Circuit shows the balun, induc-tors, and capacitors that constitute the matching net-work. Refer to the MAX2820/MAX2821 EV kit schematic for component values of the matching network.The line lengths and parasitics have a noticeable impact on the matching element values in the board-level circuit. Some empirical adjustment of LC component values is likely. Balanced line layout on the differential input traces is essential to maintaining good IP2 performance and RF common-mode noise rejection.controlled by the logic signal applied to RF_G AIN. RF_G AIN high enables the high-gain mode, and RF_GAIN low enables the low-gain mode. The LNA gain step is nominally 30dB. In most applications, RF_GAIN is connected directly to a CMOS output of the baseband IC, and the baseband IC controls the state of the LNA gain based on the detected signal amplitude.Receiver Baseband Lowpass Filtering The on-chip receive lowpass filters provide the steep filtering necessary to attenuate the out-of-band (>11MHz) interfering signals to sufficiently low levels to preserve receiver sensitivity. The filter frequency response is precisely controlled on-chip and does not require user adjustment. In the MAX2820/MAX2821, a provision is made to permit the -3dB corner frequency and entire response to be slightly shifted up or down in frequency. This is intended to offer some flexibility in trading off adjacent channel rejection vs. passband distortion. The filter -3dB frequency is programmed through the serial interface. The specific bit setting vs. -3dB frequency is shown in Table 7. The typical receive baseband filter gain vs. frequency profile is shown in the Typical Operating Characteristics.Receive Gain Control and DC Offset Nulling The receive path gain is varied through an external volt-age applied to the pin RX_AG C. Maximum gain is at V RX_AGC= 0V and minimum gain is at V RX_AGC= 2V. The RX_AG C input is a high-impedance analog input designed for direct connection to the RX_AG C DAC output of the baseband IC. The gain-control range, which is continuously variable, is typically 70dB. The gain-control characteristic is shown in the TypicalTable 8. Transmit Settings Register (TRANSMIT)MAX2820/MAX2820A/MAX2821/MAX2821AM A X 2820/M A X 2820A /M A X 2821/M A X 2821AOperating Characteristics section graph Receiver Voltage Gain vs. Gain-Control Voltage.Some local noise filtering through a simple RC network at the input is permissible. However, the time constant of this network should be kept sufficiently low in order not to limit the desired response time of the RX gain-control function.Receiver Baseband Amplifier OutputsThe receiver baseband outputs (RX_BBIP, RX_BBIN,RX_BBQP, and RX_BBQN) are differential low-imped-ance buffer outputs. The outputs are designed to be directly connected (DC-coupled) to the in-phase (I) and quadrature-phase (Q) ADC inputs of the baseband IC.The RX I/Q outputs are internally biased to +1.2V com-mon-mode voltage. The outputs are capable of driving loads up to 5k Ω|| 5pF with the full bandwidth baseband signals at a differential amplitude of 500mV P-P .Proper board layout is essential to maintain good bal-ance between I/Q traces. This provides good quadra-ture phase accuracy.Receiver Power Detector (MAX2820/MAX2821 Only)The receiver level detector is a digital output from an internal threshold detector that is used to determine when to change the LNA gain state. In most applications,it is connected directly to a comparator input of the base-band IC. The threshold level can be programmed through the MAX2820/MAX2821 control software.Transmit PathTransmitter Baseband InputsThe transmitter baseband inputs (TX_BBIP, TX_BBIN,TX_BBQP, and TX_BBQN) are high-impedance differ-ential analog inputs. The inputs are designed to be directly connected (DC-coupled) to the in-phase (I) and quadrature-phase (Q) DAC outputs of the baseband IC.The inputs must be externally biased to +1.2V common-mode voltage. Typically, the DAC outputs are current outputs with external resistor loads to ground. I and Q are nominally driven by a 400mV P-P differential base-band signal.Proper board layout is essential to maintain good bal-ance between I/Q traces. This provides good quadra-ture phase accuracy by maintaining equal parasitic capacitance on the lines. In addition, it is important not to expose the TX I/Q circuit board traces going from the digital baseband IC to the TX_BB inputs. The lines should be shielded on an inner layer to prevent cou-pling of RF to these TX I/Q inputs and possible enve-lope demodulation of the RF signal.Transmit Path Baseband Lowpass FilteringThe on-chip transmit lowpass filters provide the filtering necessary to attenuate the unwanted higher-frequency spurious signal content that arises from the DAC clock feedthrough and sampling images. In addition, the filter provides additional attenuation of the second sidelobe of signal spectrum. The filter frequency response is set on-chip. No user adjustment or programming is required. The Typical G ain vs. Frequency profile is shown in the Typical Operating Characteristics .Transmitter DC Offset CalibrationIn a zero-IF system, in order to achieve low LO leakage at the RF output, the DC offset of the TX baseband sig-nal path must be reduced to as near zero as possible.G iven that the amplifier stages, baseband filters, and TX DAC possesses some finite DC offset that is too large for the required LO leakage specification, it is necessary to “null ” the DC offset. The MAX2820 family accomplishes this through an on-chip calibration sequence. During this sequence, the net TX baseband signal path offsets are sampled and cancelled in the baseband amplifiers. This calibration occurs in the first ~2.2µs after TX_ON is taken high. During this time, it is essential that the TX DAC output is in the 0V differential state. The calibration corrects for any DAC offset.However, if the DAC is set to a value other than the 0V state, then an offset is erroneously sampled by the TX offset calibration. The TX DAC output must be put into the 0V differential state at or before the time TX_ON is taken high.Power-Amplifier Driver OutputThe TX_RF outputs are high-impedance RF differential outputs directly connected to the driver amplifier. The outputs are essentially open-collector outputs with an on-chip inductor choke connected to VCC_DRVR. The power-amplifier driver outputs require external imped-ance matching and differential to single-ended conver-sion. The balanced to single-ended conversion and interface to 50Ωis achieved through the use of an off-chip 4:1 balun transformer, such as one from Murata or TOKO. In this case, the TX RF output must be imped-ance-matched to a differential/balanced impedance of 200Ω. The Typical Application Circuit shows the balun,inductors, and capacitors that constitute the matching network of the power amplifier driver outputs. The out-put match should be adjusted until the return loss at the balun output is >10dB.。

Quad Capacitance
Capacitance of Schottky diode quads is measured using an HP4271 LCR meter. This instrument effectively isolates individual diode branches from the others, allowing accurate capacitance measurement of each branch or each diode. The conditions are: 20 mV R.M.S. voltage at 1 MHz. HP defines this measurement as “CM”, and it is equivalent to the capacitance of the diode by itself. The equivalent diagonal and adjacent capacitances can then be calculated by the formulas given below.

上海海栎创微电子有限公司 HAA2820 数据手册说明书

上海海栎创微电子有限公司HAA2820数据手册5W单声道、带有AGC防破音功能、AB/D切换、自适应电荷泵升压、自适应MUTE功能的音频功率放大器Rev：V1.02018/03/01HAA2820数据手册1.概述HAA2820是一款内置电荷泵升压的D类音频功率放大器，在4.2V电源电压的情况下，可以为4Ω负载送出5W（THD+N=10%）的输出功率。

HAA2820内置AGC模式，当输入信号较高的时候，可以自动降低内部增益，防止输出发生截顶失真，提升大音量播放音乐时的音质。

HAA2820带有OT，OC，OVP，UVLO等保护功能，有效保护芯片。

2.芯片特点◆最大输出功率: 5.06W (4.2V,4Ω,10%THD+N)；4.2W (4.2V,4Ω,1%THD+N)◆AGC Function◆AB、D function◆底噪：47uVrms(Gain=16V/V, Class D)；30uVrms(Gain=12V/V, Class AB)◆THD+N：0.005%◆效率: 71%(3.6V, 4Ω,2W)◆自适应MUTE功能◆自适应电荷泵升压功能◆UVLO，OTP，OCP◆eTSSOP-163.引脚分布/说明4.功能描述4.1 Ctrl<2:1> ControlHAA2820有四种工作状态，通过Ctrl<2:1>两个控制管脚进行控制，如下图所示。

00时芯片关断，关断电流小于1uA。

01的时候为D类工作模式，同时AGC功能开启，当输出将要出现截顶失真的时候，主动降低内部增益，使输出保持非截顶失真的状态，提高音质，有效保护喇叭。

10的时候为D类工作模式，AGC功能关闭。

11的时候为AB类工作模式，同时电荷泵不升压，处于直通模式，消除芯片对FM信号的EMI影响。

模式切换的时候需要先将Ctrl<1:0>置为00，将芯片关闭复位，再进入需要的工作模式，以防止出现异常的切换杂音。
