description
The TLC2934, a mixed signal IC designed for phase-locked-loop (PLL) systems, is composed of a
voltage-controlled oscillator (VCO) and an edge-triggered-type phase frequency detector (PFD).
The internal VCO is based on the TLC2932 and TLC2933s ring oscillator. It oscillates in wider frequency with
lower supply voltage, and it has stable oscillating performance. The oscillation function, provided by only one
external resistor connection, supplies bias to the VCI internal circuit. Oscillator range is covered from 10 MHz
to 130 MHz with a 3.3-V supply voltage. The VCO has an inhibit function to stop oscillation and for the
power-down mode.
The internal PFD, a high-speed rising edge triggered type, has an internal charge pump with a high-impedance
output buffer. The PFD detects phase difference between the reference frequency input and the signal
frequency input from the VCO output through an external counter device. This functions the same as TLC2932
and TLC2933. The PFD also has the inhibit function for stop phase comparison and for power-down mode.
