TDA5201

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.
