A 10Gb/s CMOS CDR and DEMUX IC with a Quarter-Rate Linear Phase Detector

A 10Gb/s CDR and DEMUX IC in a 0.13μm CMOS consumes 100mA from a 1.2V core supply and 205mA from a 2.5V I/O supply including 18 LVDS drivers. The CDR system uses a quarter-rate linear phase detector and a 4-phase 2.5GHz LC-QVCO to achieve a BER of <10
^-15
and a jitter tolerance of 0.5UI
_pp
exceeding the OC-192 standard
