TC5081BP
PHASE COMPARATOR
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.
FEATURES
0 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.
0 Because the IC is CMOS, the input impedance of the
filter for the amp is extremely high and has excellent
characteristics.
q TC5081BP comes in a SIP 9 PIN.
