General Description

The TLC2933 is designed for phase-locked-loop (PLL) systems and is posed of a voltage-controlled oscillator (VCO) and an edge-triggered-type phase frequency detector (PFD).

The oscillation frequency range of the VCO is set by an external bias resistor (RBIAS).

The high-speed PFD with internal charge pump detects the phase difference between the reference frequency input and signal frequency input from the external counter.
