Patent ID: 8718088

Claim:
A signal conversion method, comprising: receiving, in parallel, a first plurality of digital signals at a first clock rate and a second plurality of digital signals at a second clock rate which is slower than the first clock rate; forming one or more forward data packets in a predefined format based at least in part on the first plurality and the second plurality of digital signals; and transmitting, in series, the one or more forward data packets at a third clock rate which is faster than the first clock rate, wherein forming one or more forward data packets in a predefined format based at least in part on the first plurality and the second plurality of digital signals comprises: deserializing the first plurality of digital signals; generating digital codes according to a frequency ratio of the first clock rate and the third clock rate; oversampling the second plurality of digital signals; packing the deserialized first plurality of digital signals, digital codes of the first clock rate, and the oversampled second plurality of digital signals into the one or more forward data packets in the predefined format; and serializing the one or more forward data packets.
