TDA 5204 E1
preliminary
Product Description
2.1 Overview
The IC is a very low power consumption single chip ASK Superheterodyne
Receiver (SHR) for the frequency band 390MHz. 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 synthesiser, 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.
