31142 Description

The UTC TA31142 is a low power IF receiver IC and is suitable for use as the second IF downconverter in double-conversion paging systems. It is well-suited for POCSAG paging applications and incorporates a 2-level FSK demodulator consisting of a quadrature FM demodulator, on-chip bit-rate filter, and 1-bit parator. An on-chip 1V regulator is provided for convenient biasing of off-chip circuitry.
