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 Resistor 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 TLC2933A 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 powerdown 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 FINA and FINB as shown in Figure 2. Normally the
reference is supplied to FINA and the frequency from the external counter output is fed to FINB. For clock
recovery PLL system, other types of phase detectors should be used.
