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
of the VCO is set by an external bias resistor (R_BIAS). 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 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.
