description

The TLC2933 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

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 that can be used as a power-down mode. With the

high-speed and stable VCO characteristics, the TLC2933 is well suited for use in high-performance PLL

systems.
