The IC 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 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. | Summary of Features: Low supply current (Is = 5.7 mA typ. in FSK mode, Is = 5 mA typ. in ASK mode); Supply voltage range 5V 10%; Power down mode with very low supply current (50nA typ.); FSK and ASK demodulation capability; Fully integrated VCO and PLL Synthesiser; ASK sensitivity better than -110 dBm over specified temperature range (- 40 to +105C); Selectable frequency ranges 310- 330 MHz and 330-350 MHz; Limiter with RSSI generation, operating at 10.7MHz; Selectable reference frequency; 2nd order low pass data filter with external capacitors; Data slicer with self-adjusting threshold; FSK sensitivity better than -102 dBm over specified temperature range (- 40 to +105C) | Target Applications: Keyless Entry Systems; Remote Control Systems; Alarm Systems; Low Bitrate Communication Systems
