TDA7210
The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency bands 810 to 870 MHz and 400 to 440 MHz that is pin compatible with the Receiver TDA5210. The IC 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 PLL FSK demodulator, a data filter, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.
