description
The TLC2932 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
). The VCO has a 1/2 frequency divider at the output stage.
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,
which can be used as a power-down mode. The TLC2932 is suitable for use as a high-performance PLL due
to the high speed and stable oscillation capability of the device.
