Patent ID: 7313202

Claim:
A serial data receiver comprising: a differential receiver configured to receive first and second signals of opposite phases to provide a differential signal of the first and second signals as received serial data; a clock generator configured to generate a clock signal; a tracking circuit configured to receive the received serial data and the clock signal to generate a synchronous clock signal based on the clock signal by tracking the received serial data, the tracking circuit configured to generate a synchronous serial data synchronized with the synchronous clock signal; an idle detector configured to receive the first signal and the second signal, the idle detector configured to detect an idle period of the first and second signals to provide an idle signal; a memory configured to store the serial data in response to transitions in the synchronous clock signal, the memory configured to provide the stored data in response to transitions in the clock signal, the memory configured to stop storing based on a hold signal; and a data protector configured to receive the idle signal to generate the hold signal, the data protector configured to provide the hold signal for the memory.
