GENERAL DESCRIPTION
The UAA3220TS is a fully integrated single-chip receiver,
primarily intended for use in VHF and UHF systems.
It supports both Amplitude Shift Keying (ASK) and
Frequency Shift Keying (FSK) demodulation.
By connecting DEMO1 (pin 10) to ground during
realisation of the receiver module the UAA3220TS works
as an ASK receiver (see Fig.10). By connecting pin 10 as
shown in Fig.9 the UAA3220TS works as an FSK receiver.
The UAA3220TS incorporates a crystal stabilized local
oscillator, frequency multiplier, balanced mixer, post mixer
amplifier, limiter, Received Signal Strength Indicator
(RSSI), FSK demodulator, data filter, data slicer and
power down circuit.
