The sensors need only one PCB layer, enabling ultra thin applications.The AD7147 is an integrated CDC with on-chip environmental calibration. The CDC has 13 inputs channeled through a switch matrix to a 16-bit, 250 kHz sigma-delta (∑-Δ) converter. The CDC is capable of sensing changes in the capacitance of the external sensors and uses this information to register a sensor activation. By programming the registers, the user has full control over the CDC setup.High resolution sensors require minor software to run on the host processor.FUNCTIONAL BLOCK DIAGRAMCIN0CIN1CIN2CIN3CIN4CIN5CIN6CIN7CIN8CIN9CIN10CIN11CIN12V DRIVE GPIOSDA ADD0ADD16663-1Figure 1. AD7147 Block DiagramThe AD7147 is designed for single-electrode capacitance sensors (grounded sensors). There is an active shield output to minimize noise pickup in the sensor.The AD7147 has on-chip calibration logic to compensate for changes in the ambient environment. The calibration sequence is performed automatically and at continuous intervals as long as the sensors are not touched. This ensures that there are no false or nonregistering touches on the external sensors due to a changing environment.The AD7147 has an SPI-compatible serial interface, and the AD7147-1 has an I2C®-compatible serial interface. Both parts have an interrupt output, as well as a GPIO. There is a V DRIVE pin to set the voltage level for the serial interface independent of V CC. The AD7147 is available in a 24-lead, 4 mm × 4 mm LFCSP and operates from a 2.6 V to 3.6 V supply. The operating current con-sumption in low power mode is typically 26 μA for 13 sensors.AD7147Rev. 0 | Page 2 of 68TABLE OF CONTENTSFeatures..............................................................................................1 Applications.......................................................................................1 General description..........................................................................1 Functional Block Diagram..............................................................1 Revision History...............................................................................2 Specifications.....................................................................................3 SPI Timing Specifications (AD7147).........................................5 I 2C Timing Specifications (AD7147-1).....................................6 Absolute Maximum Ratings............................................................7 ESD Caution..................................................................................7 Pin Configurations and Function Descriptions...........................8 Typical Performance Characteristics.............................................9 Theory of Operation......................................................................11 Capacitance-Sensing Theory....................................................11 BIAS Pin.......................................................................................12 Operating Modes........................................................................12 Capacitiance-to-Digital Converter...............................................14 Oversampling the CDC Output...............................................14 Capacitance Sensor Offset Control..........................................14 Conversion Sequencer...............................................................14 CDC Conversion Sequence Time............................................16 CDC Conversion Results...........................................................16 Capacitance Sensor Input Configuration....................................17 CINx Input Multiplexer Setup..................................................17 Single-Ended Connections to the CDC..................................17 Noncontact Proximity Detection.................................................18 Recalibration...............................................................................18 Proximity Sensitivity..................................................................18 FF_SKIP_CNT.

CDC Linearity, V CC = 3.3 VTHEORY OF OPERATIONThe AD7147 and AD7147-1 are CDCs with on-chip environmental compensation. They are intended for use in portable systems requiring high resolution user input. The internal circuitry consists of a 16-bit, ∑-Δ converter that can change a capacitive input signal into a digital value. There are 13 input pins, CIN0 to CIN12, on the AD7147 or AD7147-1. A switch matrix routes the input signals to the CDC. The result of each capacitance-to-digital conversion is stored in on-chip registers. The host subsequently reads the results over the serial interface. The AD7147 has an SPI interface, and the AD7147-1 has an I2C interface, ensuring that the parts are compatible with a wide range of host processors. AD7147 refers to both theAD7147 and AD7147-1, unless otherwise noted, from this point forward in this data sheet.The AD7147 interfaces with up to 13 external capacitance sensors. These sensors can be arranged as buttons, scroll bars, or wheels, or as a combination of sensor types. The external sensors consist of an electrode on a single- or multiple-layer PCB that interfaces directly to the AD7147.The AD7147 can be set up to implement any set of input sensors by programming the on-chip registers. The registers can also be programmed to control features such as averaging, offsets, and gains for each of the external sensors. There is an on-chip sequencer that controls how each of the capacitance inputs is polled.The AD7147 has on-chip digital logic and 528 words of RAM that are used for environmental compensation. The effects of humidity, temperature, and other environmental factors can affect the operation of capacitance sensors. Transparent to the user, the AD7147 performs continuous calibration to compen-sate for these effects, allowing the AD7147 to consistently provide error-free results.The AD7147 requires a companion algorithm that runs on the host or another microcontroller to implement high resolution sensor functions, such as scroll bars or wheels. However, no companion algorithm is required to implement buttons. Button sensors are implemented on chip, entirely in digital logic.The AD7147 can be programmed to operate in either full power mode or low power automatic wake-up mode. The automatic wake-up mode is particularly suited for portable devices that require low power operation to provide the user with significant power savings and full functionality.The AD7147 has an interrupt output, INT, to indicate when new data has been placed into the registers. INT is used to interrupt the host on sensor activation. The AD7147 operates from a 2.6 V to 3.6 V supply and is available in a 24-lead, 4 mm × 4 mm LFCSP.CAPACITANCE-SENSING THEORYThe AD7147 measures capacitance changes from single-electrode sensors. The sensor electrode on the PCB comprises one plate of a virtual capacitor. The other plate of the capacitor is the user’s finger, which is grounded with respect to the sensor input.The AD7147 first outputs an excitation signal to charge the plate of the capacitor. When the user comes close to the sensor, the virtual capacitor is formed, with the user acting as the second capacitor plate.6663-17Figure 19. Capacitance-Sensing MethodA square wave excitation signal is applied to CINx during the conversion, and the modulator continuously samples the charge going through CINx. The output of the modulator is processed via a digital filter, and the resulting digital data is stored in the CDC_RESULT_Sx registers for each conversion stage, at Address 0x00B to Address 0x016.Registering a Sensor ActivationWhen a user approaches a sensor, the total capacitance associated with that sensor changes and is measured by the AD7147. If the change causes a set threshold to be exceeded, the AD7147 interprets this as a sensor activation.On-chip threshold limits are used to determine when a sensor activation occurs. Figure 20 shows the change in CDC_RESULT_Sx when a user activates a sensor. The sensor is deemed to be active only when the value of CDC_RESULT_Sx is either greater than the value of STAGEx_HIGH_THRESHOLD or less than the value of STAGEx_LOW_THRESHOLD.06663-018Figure 20. Sensor Activation ThresholdsIn Figure 20, two sensor activations are shown. Sensor Active A occurs when a sensor is connected to the positive input of the converter. In this case, when a user activates the sensor, there is an increase in CDC code, and the value of CDC_RESULT_Sx exceeds that of STAGEx_HIGH_THRESHOLD. Sensor Active B occurs when the sensor is connected to the negative input of the converter. In this case, when a user activates the sensor, there is a decrease in CDC code, and the value of CDC_RESULT_Sx becomes less than the value of STAGEx_LOW_THRESHOLD.For each conversion stage, the STAGEx_HIGH_THRESHOLD and STAGEx_LOW_THRESHOLD registers are in Register Bank 3. The values in these registers are updated automatically by the AD7147 due to its environmental calibration and adaptive threshold logic.At power-up, the values in the STAGEx_HIGH_THRESHOLD and STAGEx_LOW_THRESHOLD registers are the same as those in the STAGEx_OFFSET_HIGH and STAGEx_OFFSET_LOW registers in Bank 2. The user must program the STAGEx_OFFSET _HIGH and STAGEx_OFFSET_LOW registers on device power-up. See the Environmental Calibration section of the data sheet for more information.Complete Solution for Capacitance SensingAnalog Devices, Inc., provides a complete solution forcapacitance sensing. The two main elements to the solution are the sensor PCB and the AD7147.If the application requires high resolution sensors such as scroll bars or wheels, software is required that runs on the host processor. The memory requirements for the host depend on the sensor and are typically 10 kB of code and 600 bytes of data memory, depending on the sensor type.06663-019Figure 21. Three-Part Capacitance-Sensing SolutionAnalog Devices supplies the sensor PCB footprint designlibraries to the customer and supplies any necessary software on an open-source basis.BIAS PINThis pin is connected internally to a bias node of the AD7147. To ensure correct operation of the AD7147 connect a 10 nF capacitor between the BIAS pin and ground. The voltage seen at the BIAS pin is V CC /2.OPERATING MODESThe AD7147 has three operating modes. Full power mode, where the device is always fully powered, is suited for applications where power is not a concern (for example, game consoles that have an ac power supply). Low power mode, where the part automatically powers down when no senosr is active, is tailored to provide significant power savings compared with full power mode and is suited for mobile applications, where power must beconserved. In shutdown mode, the part shuts down completely. The POWER_MODE bits (Bit 0 and Bit 1) of the control register set the operating mode on the AD7147. The control register is at Address 0x000. Table 8 shows the POWER_MODE settings for each operating mode. To put the AD7147 intoshutdown mode, set the POWER_MODE bits to either 01 or 11. Table 8. POWER_MODE SettingsPOWER_MODE Bits Operating Mode 00 Full power mode01 Shutdown mode 10 Low power mode11 Shutdown modeThe power-on default setting of the POWER_MODE bits is 00, full power mode.Full Power ModeIn full power mode, all sections of the AD7147 remain fully powered and converting at all times. While a sensor is being touched, the AD7147 processes the sensor data. If no sensor is touched, the AD7147 measures the ambient capacitance level and uses this data for the on-chip compensation routines. In full power mode, the AD7147 converts at a constant rate. See the CDC Conversion Sequence Time section for more information.Low Power ModeWhen AD7147 is in low power mode, the POWER_MODE bits are set to 10 upon device initialization. If the external sensors are not touched, the AD7147 reduces its conversion frequency, thereby greatly reducing its power consumption. The part remains in a reduced power state while the sensors are not touched. The AD7147 performs a conversion after a delay defined by the LP_CONV_DELAY bits, and it uses this data to update the compensation logic and check if the sensors are active. The LP_CONV_DELAY bits set the delay between conversions to 200 ms, 400 ms, 600 ms, or 800 ms. When an external sensor is touched, the AD7147 begins a con-version sequence every 36 ms to read back data from the sensors. In low power mode, the total current consumption of the AD7147 is an average of the current used during a conversion and the current used while the AD7147 is waiting for the next conversion to begin. For example, when LP_CONV_DELAY l is 400 ms, the AD7147 typically uses 0.85 mA of current for 36 ms and 14 μA of current for 400 ms during the conversion interval. (Note that these conversion timings can be altered through the register settings. See the CDC Conversion Sequence Time section for more information.)The time for the AD7147 to transition from a full power state to a reduced power state after the user stops touching the external sensors is configurable. The PWR_DOWN_TIMEOUT bits (in the Ambient Compensation Control 0 (AMB_COMP_CTRL0) Register at Address 0x002) control the time delay before the AD7147 transitions to the reduced power state after the user stops touching the sensors.06663-020Figure 22. Low Power Mode OperationCAPACITIANCE-TO-DIGITAL CONVERTER The capacitance-to-digital converter on the AD7147 has a Σ-Δ architecture with 16-bit resolution. There are 13 possible inputs to the CDC that are connected to the input of the converter through a switch matrix. The sampling frequency of the CDC is 250 kHz. OVERSAMPLING THE CDC OUTPUTThe decimation rate, or oversampling ratio, is determined by Bits [9:8] of the power control (PWR_CONTROL) register (Address 0x000), as listed in Table 9.Table 9. CDC Decimation RateDECIMATION Bits Decimation Rate CDC Output Rate Per Stage (ms)00 2563.072 01 1281.536 10 640.768 11 640.768 The decimation process on the AD7147 is an averaging process,where a number of samples are taken and the averaged result is output. Due to the architecture of the digital filter employed, the number of samples taken (per stage) is equal to 3× the decimationrate. So 3 × 256 or 3 × 128 samples are averaged to obtain eachstage result.The decimation process reduces the amount of noise present inthe final CDC result. However, the higher the decimation rate,the lower the output rate per stage; therefore, there is a trade-offpossible between the amount of noise in the signal and thespeed of sampling.CAPACITANCE SENSOR OFFSET CONTROLThere are two programmable DACs on board the AD7147 to nullthe effect of any stray capacitances on the CDC measurement.These offsets are due to stray capacitance to ground.A simplified block diagram in Figure 23 shows how to apply the STAGEx_AFE_OFFSET registers to null the offsets. The 6-bitPOS_AFE_OFFSET and NEG_AFE_OFFSET bits program theoffset DAC to provide 0.32 pF resolution offset adjustment overa range of 20 pF.The best practice is to ensure that the CDC output for any stageis approximately equal to midscale (~32,700) when all sensorsare inactive. T o correctly offset the stray capacitance to ground foreach stage use the following procedure:1.Read back the CDC value from the CDC_RESULT_Sx register.2.If this value is not close to midscale, increase the value ofPOS_AFE_OFFSET or NEG_AFE_OFFSET (dependingon if the CINx input is connected to the positive or negativeinput of the converter) by 1. The CINx connections aredetermined by the STAGEx_CONNECTION registers.3.If the CDC value in CDC_RESULT_Sx is now closerto midscale, repeat Step 2. If the CDC value is furtherfrom midscale, decrease the POS_AFE_OFFSET orNEG_AFE_OFFSET value by 1. The goal is to ensure that the CDC_RESULT_Sx is as close to midscale as possible. This process is only required once during the initial capacitance sensor characterization.6663-21 Figure 23. Analog Front-End Offset ControlCONVERSION SEQUENCERThe AD7147 has an on-chip sequencer to implement conversion control for the input channels. Up to 12 conversion stages can be performed in one sequence. Each of the 12 conversions stages can measure the input from a different sensor. By using the Bank 2 registers, each stage can be uniquely configured to support multiple capacitance sensor interface requirements. For example, a slider sensor can be assigned to STAGE1 through STAGE8, with a button sensor assigned to STAGE0. For each conversion stage, the input mux that connects the CINx inputs to the converter can have a unique setting.The AD7147 on-chip sequence controller provides conversion control, beginning with STAGE0. Figure 24 shows a block diagram of the CDC conversion stages and CINx inputs. A conversion sequence is defined as a sequence of CDC conversions starting at STAGE0 and ending at the stage determined by the value programmed in the SEQUENCE_STAGE_NUM bits. Depending on the number and type of capacitance sensors that are used, not all conversion stages are required. Use the SEQUENCE_STAGE_NUM bits to set the number of conversions in one sequence. This number will depend on the sensor interface requirements. For example, the register should be set to 5 if the CINx inputs are mapped to only six conversion stages. In addition, the STAGE_CAL_EN register should be set according to the number of stages that are used. The number of required conversion stages depends solely on the number of sensors attached to the AD7147. Figure 25 shows how many conversion stages are required for each sensor and how many inputs to the AD7147 each sensor requires.。

多媒体PCI接口控制芯片SAA7146A及其应用解析

多媒体PCI接口控制芯片SAA7146A及其应用摘要：概述了多媒体处理芯片SAA7146A的主要特点，描述了其内部的主要结构和关键功能，介绍了其在视频音频处理领域的开发应用，并给出了在视频图像多媒体中相应实例。

关键词：多媒体 PCI总线信号处理图像采集现在，基于PC机的多媒体应用越来越广泛，各种视频、音频信号处理技术日新月异。

其中的关键技术之一就是计算机与各种外围多媒体器件的接口问题。

PC机可供选择的总线接口基本上有ISA、PCI、USB三种。

其中，ISA总线传输率很低，只有8MB/s，基本上已被淘汰；USB接口虽然对用户来说使用很方便，但它的数据传输率也不够高，USB1.1版的数据传输率只有12MB/s。

由于多媒体信号中的视频信号的实时处理对数据传输率要求很高，较高质量的彩色图像一般要求在30MB/s以上。

因此，具有33.3MHz主频的32位的数据传输达132MB/s，而64位的数据传输率高达264MB/s的PCI总线便在多媒体尤其是视频图像领域获得了广泛的应用。

在众多的PCI接口控制芯片中，Philips公司的SAA7146A不仅具有符合PCI协议的控制电路，还集成了功能强大的高性能视频和音频多媒体处理电路，能够与众多的视频编码器及解码器、压缩及解压缩等视频芯片和音频采样与处理芯片以及其它数字信号处理芯片进行无缝连接，完成它们与计算机机PCI总线的数据通信，为视频桌面系统、图像、声音等多媒体的应用带来极大方便。

1 SAA7146A的主要特点1.1 视频处理（1）支持帧缓冲器与系统虚拟内存之间全尺寸、全速度的视频传送，可为任何一款相应的PCI外围器件提供多种处理方式；（2）支持全带宽的PCI读写操作（最高可达132MB/s）；（3）支持虚拟内存（每个DMA通道有4MB）；（4）每帧最大可处理4095行，每行最大可处理4095个采样点；（5）具有针对视频电话和视频会议应用的图像镜像功能；（6）具有视频图像播转功能；（7）内置亮度、对比度、饱和度控制电路；（8）设置了寄存器编程序列器（RPS），能够对内部寄存器进行编程控制，可以同时处理两路异步数据流；（9）内置存储器管理单元电路（MMU），可支持Windows、Unix等系统的虚拟页模式存储器管理功能；（10）具有针对帧缓冲器的矩形裁剪功能，以减少PCI总线负载；图1 SAA7146A的原理框图1.2 音频处理（1）具有时间片序列处理功能，能够同在两个异步双向数字音频接口上实现最大256bit的音频帧的复杂控制；（2）多种同步模式支持I2S和其它音频及DSP数据模式；（3）具音频输入级监控功能，可通过软件实现峰值控制；（4）具有可编程的位时钟产生电路，从而可支持主动式和从动式两种应用。
