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 receive frequencies between 902 and 928 MHz that is pin
compatible to the ASK Receiver TDA5202. The IC offers a high level of integra-
tion 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. Addi-
tionally there is a power down feature to save battery life.
