Wireless Components
2.1 Overview
2.2 Application
2.3 Features
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
that is pin compatible with the ASK Receiver TDA5200. The IC offers a high
level of integration and needs only a few external components. The device con-
tains 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.
