Patent ID: 7627029

Claim:
A receive circuit comprising: a data input terminal to receive a stream of input data; a first sampler having a first sampler data terminal coupled to the data input terminal, a first clock terminal, and a first data output terminal; a second sampler having a second sampler data terminal coupled to the data input terminal, a second clock terminal and a second data output terminal; a comparison circuit having a first comparison-circuit input node coupled to the first data output terminal, a second comparison-circuit input node coupled to the second data output terminal, and a comparison-circuit output node; and a multiplexer having a first multiplexer input terminal coupled to the first data output terminal, a second multiplexer input terminal connected to the second data output terminal, a select terminal, and a multiplexer output terminal; wherein the comparison circuit issues an error signal in response to mismatches between first and second sampled-data streams output respectively from the first and second data output terminals.
