The TLC2942 is a multichip module product that  
uses two TLC2932 chips. The TLC2932 chip is  
composed of a voltage-controlled oscillator and  
an edge-triggered phase frequency detector. The  
oscillation frequency range of each VCO is set by  
LOGIC GND2 19  
NC – No internal connection  
an external bias resistor (R  
) and each VCO output can be a ×1 or ×1/2 output frequency. Each high speed  
BIAS  
PFD with internal charge pump detects the phase difference between the reference frequency input and signal  
frequency input from the external counter. The VCO and the PFD have inhibit functions that can be used as a  
power-down mode. The high-speed and stable oscillation capability of the TLC2932 makes the TLC2942  
suitable for use in dual high-performance phase-locked loop (PLL) systems.
