description
The TLC2932A 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 TLC2932A high speed and stable oscillation capability,
the TLC2932A is suitable for use as a high-performance PLL.

detailed description
VCO oscillation frequency
The VCO oscillation frequency is determined by an external register (RBIAS) connected between the VCO VDD
and the BIAS terminals. The oscillation frequency and range depends on this resister value. For the lock
frequency range refer to the recommended operating conditions. Figure 1 shows the typical frequency variation
and VCO control voltage.

VCO output frequency 1/2 divider
The TLC2932A SELECT terminal sets the fOSC VCO output frequency as shown in Table 1. The 1/2 fOSC output
should be used for minimum VCO output jitter.

VCO inhibit function
The VCO has an externally controlled inhibit function which inhibit the VCO output. A high level on the VCO
INHIBIT terminal stops the VCO oscillation and powers down the VCO. The output maintains a low level during
the power−down mode as shown in Table 2.

PFD operation
The PFD is a high-speed, edge-triggered detector with an internal charge pump. The PFD detects the phase
difference between two frequency inputs supplied to FIN−A and FIN−B as shown in Figure 2. Normally the
reference is supplied to FIN−A and the frequency from the external counter output is fed to FIN−B. For clock
recovery PLL system, other types of phase detectors should be used.

A high level on the PFD INHIBIT terminal places PFD OUT in the high-impedance state and the PFD stops
phase detection as shown in Table 3. A high level on the PFD INHIBIT terminal can also be used as the
power-down mode for the PFD.
