Abstract:
A clock and data recovery circuit with jitter tolerance enhancement is provided. The CDR circuit includes: a bang-bang phase detector, a digital filter, a digitally controlled oscillator, and an adaptive loop gain control circuit. The CDR circuit detects a loop bandwidth variation and adjusts the loop bandwidth of CDR circuit by adjusting proportional path and integral path gain factors of the digital filter of the CDR circuit. The loop gain controller uses two methods to adjust the loop gain in CDR circuit: bang-bang adjusting method and linear adjusting method.

Claim (Index 14):
The CDR circuit according to  claim 1 , wherein the phase detector comprises:\n a half rate bang-bang phase detector, respectively sampling the input data signal by the sampling clock signal at rising edges and falling edges of the sampling clock signal to generate a plurality of first sampled data sampled at the rising edges and a plurality of second sampled data sampled at the falling edges; a de-multiplexer, coupled to the half rate bang-bang phase detector, converting the plurality of first sampled data and the plurality of second sampled data to a plurality of rising edge sampled data and a plurality of falling edge sampled data; and a decision and voting circuit, coupled to the de-multiplexer, generating final early or late information according to the plurality of rising edge sampled data and the plurality of falling edge sampled data, and generating the phase difference information signal according to the early or late information.
