描述 Description

GENERAL DESCRIPTION
The UAA2080 is a high-performance low-power radio receiver circuit primarily intended for VHF, UHF and 900 MHz pager receivers for wide area digital paging systems, employing direct FM non-return-to-zero (NRZ)
frequency shift keying (FSK).FEATURES
? Wide frequency range: VHF, UHF and 900 MHz bands
? High sensitivity
? High dynamic range
? Electronically adjustable filters on chip
? Suitable for data rates up to 2400 bits/s
? Wide frequency offset and deviation range
? Fully POCSAG compatible FSK receiver
? Power on/off mode selectable by the chip enable input
? Low supply voltage; low power consumption
? High integration level
? Interfaces directly to the PCA5000A, PCF5001 and PCD5003 POCSAG decoders.APPLICATIONS
? Wide area paging
? On-site paging
? Telemetry
? RF security systems
? Low bit-rate wireless data links.
