TDA5200 Datasheet, PDF (7/43 Pages) Infineon Technologies AG – ASK Single Conversion Receiver

TDA 5200
Product Description
2.1 Overview
The IC is a very low power consumption single chip ASK Single Conversion
Receiver for the frequency bands 868-870 MHz and 433-435 MHz. The IC
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 gen-
erator, a data filter, a data comparator (slicer) and a peak detector. Additionally
there is a power down feature to save battery life.
