Abstract :
A clock-recovery circuit is reported that employs a phase-locked loop (PLL) at 56.88 Gbit/s, and is demonstrated by locking to a 28.44 GHz sinusoidal signal while two additional circuits with adapted on-chip passive components are locked to 29 and 39 Gbit/s pseudorandom bit sequences. To the knowledge of the authors, this is the first demonstration of an integrated PLL integrated circuit for clock recovery at a data rate well above 40 Gbit/s
