  • Abstract
    A 3times oversampling CDR and 1:16 DEMUX occupies 0.8 times 1.8mm2 in a 90nm CMOS process. The chip operates at 40 to 44Gb/s and dissipates 0.91W. Input data is sampled using a 24-phase distributed VCO and a digital CDR recovers 16 bits and a 2.5GHz clock from 48 demultiplexed samples spanning 16UI. Conformance to the ITU G.8251 jitter tolerance mask (BER <10-12 with a 231 - 1 PRBS source) is demonstrated.
