Abstract :
This paper presents a quad-channel serial-link transceiver which provides 12.5 Gb/s full duplex raw data rate for a single 10 Gb XAUI interface. A mixed-mode LMS adaptive equalizer is adopted, which achieves 3 dB SNR improvement over pre-emphasis techniques. A delay-immune CDR circuit recovers the receive clock with 64 ps-pp jitter. The IC consumes 718 mW at 3.125 Gb/s/ch with full duplex data rate.
