UAA3220TS
Information as of 2000-08-19
UAA3220TS; Frequency Shift Keying (FSK)/Amplitude Shift Keying (ASK) receiver
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 . By connecting pin 10 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.
