DIGITAL CLOCK PLACEMENT ENGINE APPARATUS AND METHOD WITH DUTY CYCLE CORRECTION AND QUADRATURE PLACEMENT
摘要:
A digital clock placement engine has circuitry that adjusts a duty cycle of a clock signal and adjusts the locations of the rising/falling edges of the clock signal for purposes of data sampling or other operations. In a forwarded-clock interface implementation, a clock signal is received along with a data signal, and the received clock signal may be distorted to due various factors. To enable the received data signal to be sampled correctly, the clock placement engine generates a recovered clock signal having rising and falling edges that are placed/timed between the rising and falling edges of the received clock signal.
