Abstract:
1. A method for combining serial data streams, the method comprising: in an interface having N input terminals and N/2 output terminals, receiving N serial data signals having a first data rate, wherein N is an even integer; recovering a first serial data signal received at a first of the N input terminals to generate a first clock signal operating at the first data rate in a first clock domain; dividing the first clock signal to generate a second clock signal operating at a second data rate in the first clock domain; applying a first set of recovered data signals at respective inputs of a first 2×1 multiplexer to generate a representation of the first serial data signal; recovering a second serial data signal received at a second of the N input terminals to generate a third clock signal operating at the first data rate in a second clock domain; dividing the third clock signal to generate a fourth clock signal operating at the second data rate in the second clock domain; applying a second set of recovered data signals at respective inputs of a 1×M demultiplexer operating in accordance with the fourth clock signal to generate a first representation of the second serial data signal, where M is an even integer; applying the first representation of the second serial data signal at an input of a 1×M multiplexer operating in accordance with the second clock signal to generate a second representation of the second serial data signal; and applying the representation of the first serial data signal and the second representation of the second serial data signal to the inputs of a second 2×1 multiplexer operating in accordance with the first clock signal to generate a combined serial data signal.
