Frequency Shift Keying (FSK) receiver

Preliminary specification

UAA3202M

FEATURES

• Low cost single-chip FSK receiver

• Superheterodyne architecture with high integration level

• Few external low cost components

• Wide supply voltage range

• Low power consumption

• Wide frequency range, 150 to 450 MHz

• High sensitivity

• IF band determined by application

• High selectivity

• Very low spurious radiation, −60 dBm

(meets FTZ 17TR2100)

• Automotive temperature range

• Power-down mode

• SSOP20 package.

GENERAL DESCRIPTION

The UAA3202M is a fully integrated single-chip receiver,

primarily intended for use in VHF and UHF systems

employing direct Frequency Shift Keying (FSK)

modulation. The UAA3202M incorporates a SAW

stabilized local oscillator, balanced mixer, IF amplifier,

limiter, Received Signal Strength Indicator (RSSI), RSSI

comparator, FSK demodulator, data filter and data slicer.

The device features a power-down mode in order to

minimize the average receiver supply current.

Applications

• Keyless entry systems

• Car alarm systems

• Remote control systems

• Security systems

• Telemetry systems

• Wireless data transmission

• Domestic appliances.
