Philips Semiconductors
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.
