TDA5204RF/IF射频/中频RFID的射频接收器规格书PDF中文资料

TDA5204属于RF/IF射频/中频RFID的射频接收器。由英飞凌科技股份公司制造生产的TDA5204射频接收器RF 接收器用于接收已调制的射频信号并对其进行解调，然后将数据传送到系统中进行处理。频率范围是 AM、FM、WB、0 Hz 至 64 GHz，数据速率为 250 bps 至 16 Gbps，数据接口包括连接器、I2C、I2S、引脚焊盘、并行、PCB、串行、焊盘、SPI、UART 和 USB。

The IC is a very low power consumption single chip ASK Superheterodyne Receiver (SHR) for the frequency band 390MHz. The SHR offers a high level of integration and needs only a few external components. The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesiser, a crystal oscillator, a limiter with RSSI generator, a data filter, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.
