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 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. 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 SELECT AVAILABLE OPTIONS PACKAGE TA SMALL OUTLINE (PW) –20 °C to 75°C TLC2932IPWLE Copyright © 1997, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
