description

The TLC2933A is designed for phase-locked loop (PLL) systems and is composed 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.

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. Both the VCO and the PFD have inhibit functions,

which can be used as power-down mode. Due to the TLC2933A high speed and stable oscillation capability,

the TLC2933A is suitable for use as a high-performance PLL.
