2.1
The IC is a very low power consumption single chip ASK Superheterodyne Receiver (SHR) for the frequency
bands 315 MHz and 345 MHz. The SHR 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.
