The oscillation frequency range of the VCO is set by an external bias resistor (RBIAS). 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. functional block diagram Phase Frequency Detector 4 5 9 6 FIN −A FIN −B PFD INHIBIT PFD OUT Voltage- Controlled Oscillator 12 13 10 3 VCO IN BIAS VCO INHIBIT VCO OUT 2 TEST AVAILABLE OPTIONS PACKAGE TA SMALL OUTLINE (PW) −20 °C to 75°C TLC2933IPW† † The PW package is available taped and reeled.
