The TC5081BP is phase comparator for PLL frequency synthesizer type, and consists of a digital phase comparator and an amplifier for active low pass filter.
The phase comparator detects two input pulse phase differences and outputs proportionate positive or negative pulses to PDout. When the input pulse phases are the same, PDout has high impedance.
Because the IC is CMOS, the input impedance of the filter for the amp is extremely high and has excellent characteristics.
