Abstract :
A CDR for source-synchronous high-density link applications receives 25Gb/s at a BER of <10-12. The CDR is a first-order bang-bang topology employing a phase interpolator, linear half-rate phase detector, an analog filter followed by a limiter and a digital loop filter. The core CDR circuit occupies 0.09mm2 and consumes 98mW from a 1.1V supply
