Receiver rate converter phase calculation apparatus and method

摘要

A communication system includes a timing circuit which generates phase conversion information from a transmitter to transfer data from a first clock domain to a second clock domain, and a receive phase calculation circuit which utilizes the phase information from the transmitter to transfer data from the second clock domain to the first clock domain. The timing circuit includes a transmit (TX) numerical controlled oscillator (NCO) and a modulo indicator, and the receive phase calculation circuit calculates a receive phase based on a modulo signal.
