ABSTRACT:
A clock generator is provided for a transmitter in a transceiver adapted to communicate data over a serial data link. The transceiver includes a clock data recovery circuit recovers a receive clock signal and outputs a reference clock signal. The clock generator includes a local clock, a frequency difference detector, and a fractional-N frequency synthesizer. The local clock outputs a local clock signal. The frequency difference detector outputs a fractional frequency difference signal based on a frequency difference between the local clock signal and the reference clock signal. The fractional-N frequency synthesizer outputs a transmit clock signal having a same frequency as the recovered receive clock signal.
