Patent ID: 6928573

Claim:
Apparatus for converting serial data clocked in response to a first clock signal having cycles occurring at a first rate to serial data clocked in response to a second clock signal having cycles occurring at a second rate, the second rate being equal to or greater than the first rate, the apparatus comprising: first flip-flops arranged to store the data clocked in response to the first clock signal; a first signal generator responsive to the first clock signal arranged to generate a first enable signal after a predetermined number of cycles of the first clock signal dependant on the number of first flip-flops; second flip-flops responsive to the first enable signal and the first clock signal arranged to store the data; a second signal generator arranged to generate a second enable signal in response to the second clock signal and the first enable signal; third flip-flops arranged to store the data in response to the second enable signal and the second clock signal; and a multiplexer arranged to transmit the data in serial form from the third flip-flops at the second rate.
