编码解码芯片PT2262PT2272芯片原理及编码说明

编码解码芯片PT2262/PT2272芯片原理及编码说明PT2262/2272是台湾普城公司生产的一种CMOS工艺制造的低功耗低价位通用编解码电路，PT2262/2272最多可有12位(A0-A11)三态地址端管脚(悬空,接高电平,接低电平),任意组合可提供531441地址码,PT2262最多可有6位(D0-D5)数据端管脚,设定的地址码和数据码从17脚串行输出，可用于无线遥控发射电路。

编码芯片PT2262发出的编码信号由：地址码、数据码、同步码组成一个完整的码字，解码芯片PT2272接收到信号后，其地址码经过两次比较核对后，VT脚才输出高电平，与此同时相应的数据脚也输出高电平，如果发送端一直按住按键，编码芯片也会连续发射。

当发射机没有按键按下时，PT2262不接通电源，其17脚为低电平，所以315MHz 的高频发射电路不工作，当有按键按下时，PT2262得电工作，其第17脚输出经调制的串行数据信号，当17脚为高电平期间315MHz的高频发射电路起振并发射等幅高频信号，当17脚为低平期间315MHz的高频发射电路停止振荡，所以高频发射电路完全收控于PT2262的17脚输出的数字信号，从而对高频电路完成幅度键控（ASK调制）相当于调制度为100％的调幅。

PT2262特点l CMOS工艺制造，低功耗l 外部元器件少l RC振荡电阻l 工作电压范围宽：2.6-15vl 数据最多可达6位l 地址码最多可达531441种应用范围l 车辆防盗系统l 家庭防盗系统l 遥控玩具l 其他电器遥控引脚图：此主题相关图片如下：管脚说明名称管脚说明A0-A11 1-8、10-13 地址管脚,用于进行地址编码,可置为“0”,“1”,“f”(悬空), D0-D5 7-8、10-13 数据输入端，有一个为“1”即有编码发出，内部下拉Vcc 18 电源正端（＋）Vss 9 电源负端（－）TE 14 编码启动端，用于多数据的编码发射，低电平有效；OSC1 16 振荡电阻输入端，与OSC2所接电阻决定振荡频率；OSC2 15 振荡电阻振荡器输出端；Dout 17 编码输出端（正常时为低电平）此主题相关图片如下：此主题相关图片如下：地址码和数据码都用宽度不同的脉冲来表示，两个窄脉冲表示“0”；两个宽脉冲表示“1”；一个窄脉冲和一个宽脉冲表示“F”也就是地址码的“悬空”此主题相关图片如下：上面是我们从超再生接收模块信号输出脚上截获的一段波形，可以明显看到，图上半部分是一组一组的字码，每组字码之间有同步码隔开，所以我们如果用单片机软件解码时，程序只要判断出同步码，然后对后面的字码进行脉冲宽度识别即可。

Volume Controller IC PT2259 DESCRIPTIONPT2259 is an 8-pin 2-channel volume controller which utilizes CMOS technology and incorporates the I2C interface control. The controller features an attenuation range of 0 to -79dB, low noise output, a high degree of stereo separation and requires only a small number of external components. PT2259 is an essential component for modern audio visual systems.FEATURES•Attenuation range: 0 to –79dB in 1dB steps•Operating voltage: 4 to 9V•Low power consumption•Low signal noise: S/N > 100dB (A-weighting)•Stereo separation > 100dB•Requires few external components•2-channel volume individual adjust•Available in 8 Pins DIP or SOPAPPLICATIONS•Audio/visual surround sound systems•Car audio systems• Mini-compo systems•Computer multi-media speakers•Other audio applicationsVolume Controller IC PT2259BLOCK DIAGRAMVolume Controller IC PT2259PIN CONFIGURATIONPT225912348765LIN LOUT VSS SDARIN ROUT VDD SCLPIN DESCRIPTIONPin NameI/O DescriptionPin No.LIN ILeft Channel Input(capacitor coupled to input port) 1 LOUT OLeft Channel Output(capacitor coupled to output port)2VSS - Ground 3 SDA I I 2C Data Input 4 SCL I I 2C Clock Input 5VDD - Power Supply6 ROUT ORight Channel Output(capacitor coupled to input port) 7 RIN IRight Input Channel(capacitor coupled to output port)8Volume Controller IC PT2259 FUNCTIONAL DESCRIPTIONI2C BUS INTERFACEIn PT2259 the DATA and CLK make up the bus interface through which data is transmitted to and from the microprocessor.DATA VALIDITYData on the DATA line is considered valid and stable only when the CLK signal is in the “high” state. In addition, the “high” and “low” states of the DATA line can change only when the CLK signal is in the “low” state. Please refer to the diagram below:START AND STOP CONDITIONSA start condition is activated when:1. the CLK signal is set to “high”, and2. the DATA signal shifts from “high” to “low”A stop condition is activated when:1. the CLK signal is set to “high”, and2. the DATA signal shifts from “low” to “high”Please refer to the timing diagram below:Volume Controller IC PT2259 BYTE FORMATEvery byte transmitted to the DATA line consists of 8 bits and each byte must be followed by an “acknowledge” bit. The MSB is transmitted first.ACKNOWLEDGE SIGNALDuring the ninth clock pulse, the microprocessor puts a resistive “high” level on the DATA line. If the peripheral audio processor (PT2259) acknowledges, it will pull the DATA line from a “high” state to a “low” state during this acknowledge clock phase so that the DATA line is in a stable “low” state during this clock pulse. Please refer to the diagram below.The audio processor that has been address (PT2259) must generate an “acknowledge” signal after receiving each byte or the DATA line will remain at the “high” level during the ninth clock pulse. TRANSMISSION WITHOUT ACKNOWLEDGEIf you do not wish the audio processor (PT2259) to detect the “acknowledge” signal, a simpler microprocessor transmission method can be used: after PT2259 has received a byte wait for one clock pulse and do not acknowledge it. If this approach is used, however, there is a greater chance for faulty operations to occur and noise immunity will be decreased.Volume Controller IC PT2259 I2C START TIMEWhen PT2259 is powered on, a short period must elapse before voltage becomes stable. After the power is turned on, PT2259 must wait at least 200ms before it is able to send an I2C control signalotherwise control efficacy and normal operation will be comprised. Please refer to the diagram below:VDDVolume Controller IC PT2259 INTERFACE PROTOCOLThe interface protocol consists of the following:1. a start condition2. the PT2259 address byte followed by an “acknowledge” signal3. a data sequence (n-bytes and an “acknowledge” signal)4. a stop conditionPlease refer to the following diagram:Note: ACK=ACKNOWLEDGEMax Clock Speed = 100K BITS/SSOFTWARE SPECIFICATIONSPT2259 address is shown below:1 MSB 0 0 0 1 0 0 0LSBVolume Controller IC PT2259 DATA BYTES DESCRIPTIONFUNCTION BITSMSB LSB Function-1dB/step1 1 0 1 A3 A2 A1 A0 2-channel,-10db/step2-channel,1 1 1 0 0 B2 B1 B0channel,-1db/step1 0 1 0 A3 A2 A1 A0 Left-10dB/stepchannel,Left1 0 1 1 0 B2 B1 B0-1dB/stepchannel,0 0 1 0 A3 A2 A1 A0 Right-10dB/stepchannel,Right0 0 1 1 0 B2 B1 B0register1 1 1 1 0 0 0 0ClearselectMute0 1 1 1 0 1 C1 C0ATTENUATION UNIT BITSA3 A2/B2 A1/B1 A0/B0 Attenuation (dB)0 0 0 0 0/00 0 0 1 -1/-100 0 1 0 -2/-200 0 1 1 -3/-300 1 0 0 -4/-400 1 0 1 -5/-500 1 1 0 -6/-600 1 1 1 -7/-701 0 0 0 -8/1 0 0 1 -9/ MUTE FUNCTION BITSC1 C0 Function0 0OFFMute0 1 Right channel mute ON1 0 Left channel mute ON1 1 Left and right channel mute ONVolume Controller IC PT2259 PT2259 CONTROL SOFTWARE PROCEDUREPT2259 has a built-in Power-On Reset function which clears the function register to zero after power-on. In order to ensure normal operation under any operating voltage, it is recommended an instruction to clear the register must be transmitted. Please refer to the following diagram: Start 1 0 0 0 1 0 0 0 ACK 1 1 1 1 0 000ACK Stop2259 Address Clear RegistryThe PT2259 function register does not have any default settings. After clearing the register, an initial value must send in order to each register. If a register does has not been set, it is possible that no sound will be output.When adjusting the volume of PT2259, it is necessary to send a multiple of 10dB followed by a 1dB code to the attenuator in sequence. If this sequence is not followed, or if only a 10dB or 1dB value is sent, the IC may not operate normally. Please refer to the diagram below:Example : Request volume setting of –42dB:Start 1 0 0 0 1 0 0 0 ACK 1 1 1 0 0 100ACK11010010ACK StopAddress-40dB -2dB2259Start 1 0 0 0 1 0 0 0 ACK 1 1 0 1 0 010ACK11100100ACK Stop-2dB -40dB2259AddressThe two methods above are both acceptable.WARNING!

基于PT2258的AV5.1多声道音响控制系统

基于PT2258的AV5．1多声道音响控制系统引言随着居民收入的增加，消费者早已容易获得较好的、廉价的视频及音频信号源，如RADIO、TV、CD、VCD、DVD 等，特别是VCD、DVD 的普及，人们普遍把AV 功放搬回家，逐步实现了家庭影院的声响效果。

然而上述音频信号源都有各自独立的音响，声道也是独立控制的，使用时既繁琐，又不能让众多音频源共享AV 功放优质的声响，减少了使用的乐趣。

在这种背景下，针对目前家庭众多音频信号源控制离散的问题，我们研制开发了基于PT2258 的AV5．1 音响控制系统，提供一种具有较高性价比、方便使用的红外遥控音频控制平台，将各种音频信号源选择输入至AV 功放，统一控制。

该控制系统已成功运用于深圳某音响企业，效果良好。

1 硬件电路构成本设计以Microchip 公司的PICl6C56 为主控IC，系统硬件电路框图如图1 所示。

通过模拟开关选择音频信号源，输入至声道音量控制芯片PT2258 中，由主控IC 接收、分析键盘模块或红外遥控的数据，控制PT2258 实现音量的升降、重音增减、静音开关等功能，最后输出至后续的AV 功放。

1．1 声道控制PT2258 PT2258 是普诚公司推出的CMOS 工艺制造的声道音量控制IC。

其工作电压范围宽(5～9 V)，6 声道设计(O～一79 dB)，极低噪声(S／Nl00 dB)，高分辨率(100 dB)，极少的外围电路以及与处理器方便连接的I2C 控制总线，使其在汽车音响、电脑多媒体、AV 环绕视听等方面具有广泛的应用，是AV 多声道音响系统极佳的音量控制元件。

PT2258 外围电路连接如图2 所示。
