... 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 ...
