【应用】EPSON SR3225SAA射频发射器模块在汽车无线钥匙的应用
汽车遥控门禁系统采用专用的防盗技术，安全性高、使用方便，广泛的应用在现代的汽车中。该系统通过钥匙端射频电路发送一串特殊编码数据，在汽车接收端进行解码运算，根据解析后提取的命令码进行相应的操作，如开车门、关车门、开后备箱等，其通讯系统原理图如图1所示。
图1. 汽车无线钥匙通讯原理图
传统的无线钥匙通常采用“发射芯片+晶振+通讯转换电路+MCU”的方式实现，笔者在此推荐EPSON公司的无线发射芯片SR3225SAA，如图2所示。该模块在3.2*2.5*1.0mm的尺寸中封装了EPSON公司32MHz精密晶体谐振器和振荡电路，并集成了稳定的无线发射的功能，通过SPI接口与外部MCU连接，即可实现数据发射。并且该模块具有超低的功耗，在掉电模式下仅20nA，有利于延长无线钥匙的电池使用时间。

除此以外，SR3225SAA射频发射器模块支持UHF波段的 300 MHz~465 MHz和 600 MHz~930 MHz载波频段，并可分别实现0.25KHz和0.49KHz步进；且支持ASK、OOK、FSK，并且可选择软ASK和/或软FSK（用于限制传输带宽）多种调制方式，输出级带有可编程功率放大器，可实现在 -15~11dBm发射功率范围内128等级的输出选择，用户可根据实际应用对功耗进行优化，有利于降低产品的发射功耗，延长电池使用时间。
EPSON公司对该模块的锁相环电路进行了加强优化设计，采用具有基于Δ-Σ调制的N分频的锁相环，量化误差噪声被大大抑制，使之具有更高的频率分辨率和稳定性。而且集成了PLL失锁，VCO自动校准错误，欠压检测等故障保护功能，使产品的可靠性大大增加。如图3所示。

SR3225SAA射频发射器模块的工作温度范围-40~85℃，达到工业级的温度等级；在掉电模式下电流仅20nA(典型值)，工作时仅12.7mA，并具有多种方式优化功耗，满足无线钥匙低功耗设计要求；晶振频率公差±2ppm，在整个工作温度范围内，变化才±20ppm，具有很高的精度和稳定度，有助于发射信号的稳定；发射比特率可达100kbps（ASK）和50kbps(FSK)，满足大多数通讯场合的应用要求。
