General Description

The TLC2932 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 VCO has a 1/2 frequency divider at the output stage.
