A 10Gb/s NRZ receiver with feedforward equalizer and glitch-free phase-frequency detector
2009
A 10Gb/s NRZ receiver with feedforward equalizer and CDR is described. The CDR incorporates an LC oscillator with a range of 8.3 to 11.1 GHz and a new glitch-free binary PFD. The glitch-free architecture minimizes the jitter generation of the CDR and increases jitter tolerance. The CDR loop employs a V/I converter with two independent charge-pumps for FD and PD signals to achieve fast acquisition and low jitter generation simultaneously.
