GENERAL DESCRIPTION
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. s 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 +105°C) s Selectable frequency ranges 310330 MHz and 330-350 MHz Limiter with RSSI generation, operating at 10.7MHz Selectable reference fre
