General Description
The IC is a very low power consump- ^Package
tion single chip FSK/ASK Superhet-
erodyne 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 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 lim-
iter with RSSI generator, a PLL FSK
demodulator, a data filter, a data com-
parator (slicer) and a peak detector.
Additionally there is a power down fea-
ture to save battery life.
