CD4046B

The CD4046B CMOS microprocessor phase-locked loop(PLL) consists of a low power, linear voltage-controlled oscillator(VCO) and two different phase comparators having a common signal-input amplifier and a common comparator input.

Features of the CD4046B are:(1)very low power consumption; (2)operating frequency range up to 1.4 MHz typ; (3)low frequency drift; (4)VCO inhibit control for ON-OFF keying and ultra-low standby power consumption; (5)source-follower output of VCO control input(demod,output); (6)zener diode to assit supply regulation; (7)100% tested for quiescent current at 20 V.

The absolute maximum ratings of the CD4046B can be summarized as:(1): DC supply-voltage range(VDD) is -0.5 V to +20 V(voltages referenced to Vss terminal); (2): input voltage range, all inputs is -0.5 V to VDD+0.5 V; (3): DC input current, any one input is ±10 mA; (4): operating temperature range(Ta) is -55 to +125; (5): storage temperature range(Tstg) is -65 to +150.
