Abstract

An 8.5-11.5Gbps SONET transceiver with a referenceless CDR employing an algorithmic frequency acquisition scheme (without using any training sequence) is designed in a 65nm digital CMOS process. A modified digital quadricorrelator frequency detector (M-DQFD) is incorporated into an LC-based VCO coarse tuning adjustment. The transceiver complies with stringent SONET OC-192 jitter requirements. Within a 400μs acquisition time, the RX achieves a high-frequency jitter tolerance of 0.58UIpp at 10mVpp-diff input sensitivity. The TX serial output exhibits a random jitter (RJ) of 205fs (rms). The transceiver occupies 0.97mm2 and consumes 141mA at 1.0V.
