Challenges in the Design of HighSpeed Clock and Data Recovery Circuits(2002)
by
Behzad Razavi, University of California, Los Angeles
ABSTRACT
This article describes the challenges in the
design of monolithic clock and data recovery circuits
used in high-speed transceivers. Following
an overview of general issues, the task of phase
detection for random data is addressed. Next,
Hogge, Alexander, and half-rate phase detectors
are introduced and their trade-offs outlined.
Finally, a number of clock and data recovery
architectures are presented. |
