Phase-frequency detector with charge pump
Phase-frequency detector (PFD) forms control signal for VCO tuning. PFD compares phases of divided VCO signal and divided reference oscillator signal and detects phase difference. Charge pump generates pulses for loop filter.
Reference frequency 0.1..25 MHz. Output current is 44...647 uA.
Reference frequency 0.1..25 MHz. Output current is 44...647 uA.
