Abstract
A clock/data recovery circuit includes an edge detector circuit operable to receive a serial data burst and to generate a reset signal in response to a first edge of the serial data burst. The clock/data recovery circuit may also include an oscillator coupled to the edge detector circuit. The oscillator locks onto a target data rate prior to receipt of the serial data burst and locks onto a phase of the serial data burst in response to the reset signal. The clock/data recovery circuit may also include a phase detector circuit that receives the serial data burst. The phase detector circuit is coupled to the oscillator. The phase detector circuit adjusts the oscillator to maintain the lock onto the phase of the serial data burst during the serial data burst.
