Target Specification, October 2001
2.1
Overview
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.
The IC offers a high level of integration and needs only a few external compo-
nents. 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.
