• Superheterodyne architecture with high integration level
• Few external low cost components and crystal required
• Wide supply voltage range
• Low power consumption
• Wide frequency range, 250 to 920 MHz
• High sensitivity
• IF bandwidth determined by application
• High selectivity
• Automotive temperature range
• SSOP24 package.
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.
Applications
• Keyless entry systems
• Car alarm systems
• Remote control systems
• Security systems
• Telemetry systems
• Wireless data transmission
• Domestic appliance.
