UTCTA31142 LINEAR INTEGRATED CIRCUIT
LOW POWER IF RECEIVER IC
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 comparator. An on-chip 1V regulator is
provided for convenient biasing of off-chip circuitry.
FEATURES
*Extremely low power operation with power-down
feature
*Built-in crystal oscillator for mixer local oscillator
*Mixer input frequency: 10-50 MHz
*Quadrature detector
*On-chip bit-rate filter
*Audio output
*1-bit comparator with open collector output
*1V regulator
*1.1V low battery alarm
