TDA5201屬于RF/IF射頻/中頻RFID的射頻接收器。由英飛凌科技股份公司制造生產(chǎn)的TDA5201射頻接收器RF 接收器用于接收已調(diào)制的射頻信號(hào)并對其進(jìn)行解調(diào)，然后將數(shù)據(jù)傳送到系統(tǒng)中進(jìn)行處理。頻率范圍是 AM、FM、WB、0 Hz 至 64 GHz，數(shù)據(jù)速率為 250 bps 至 16 Gbps，數(shù)據(jù)接口包括連接器、I2C、I2S、引腳焊盤、并行、PCB、串行、焊盤、SPI、UART 和 USB。

General Description

The IC is a very low power consumption single chip ASK Single Conversion Receiver for receive frequencies between 310 MHz and 350 MHz. The Receiver 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 synthesizer, 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.
