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.
