Phase-locked Loop High-performance Silicon-gate Cmos Korea Corp.

The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The KK74HC4046A phase-locked loop contains three phase Comparators a voltage-controlled Oscillator (VCO) and unity gain op- amp DEMOUT. The Comparators have two common signal inputs, COMPIN, and SIGIN. Input SIGIN and COMPIN CAN be used directly coupled to large voltage signals, or indirectly coupled (with a series capacitor to small voltage signals). The self-bias circuit adjusts small voltage signals in the linear region of the Amplifier Phase Comparator 1 (an exclusive OR gate) provides a digital error signal PC1OUT and maintains 90 degrees phase shift at the center frequency between SIGIN and COMPIN signals (both at 50% duty cycle). Phase Comparator 2 (with leading-edge sensing logic) provides digital error signals PC2OUT and PCPOUT and maintains a 0 degree phase shift between SIGIN and COMPIN signals (duty cycle is immaterial). The linear VCO produces an output signal VCOOUT whose frequency is determined by the voltage of input VCO signal and the capacitor and resistors connected to pins C1A, By Kodenshi Korea Corp.
