UTC TA31142
LOW POWER IF RECEIVER IC
DESCRIPTION
and
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
*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

... UTC TA31142 LINEAR INTEGRATED CIRCUIT FUNCTIONAL DESCRIPTION The UTC TA31142 IF receiver IC incorporates a mixer, crystal-based local oscillator, IF amplifier, quadrature FM demodulator, bit-rate filter, and 1–bit comparator and is capable of demodulating 2-level FSK input signals. In addition, 1.0V regulator and 1.1V low battery alarm functions are provided. POWER-DOWN FUNCTION The entire receiver IC may be powered up and down through the control of the BS input (pin13). During power down operation, the quiescent current consumption of the IC drops to approximately 0µ ...
