Product Summary
The TDA5211 is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency band 310 to 350 MHz that is pin compatible with the ASK Receiver TDA5201. The TDA5211 offers a high level of integration and needs only a few external components. The TDA5211 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. The applications of the TDA5211 include Keyless Entry Systems, Remote Control Systems, Alarm Systems, Low Bitrate Communication Systems.
