CLOCK AND DATA RECOVERY WITH
INTEGRATED CLOCK MULTIPLIER UNIT
DESCRIPTION
FEATURES
SY87721L
s Recovers any data and clock from 28Mbps to
2.7Gbps
OC-1, OC-3, OC-12, OC-48, ATM
Gigabit Ethernet, Fast Ethernet
Fibre Channel, 2x Fibre Channel
P1394, Infiniband
SMPTE-259, SMPTE-292
Proprietary optical transport
s Integrated clock multiplier unit with low jitter
generation
s Complies with Bellcore, ITU/CCITT and ANSI
specifications
s Selectable mux for pass through; avoids jitter
accumulation when switching through backplanes
s Available in 64-Pin EPAD-TQFP package
The SY87721L is a complete Clock Recovery and Data
retiming integrated circuit for data rates from 28Mbps up to
2.7Gbps NRZ including SONET FEC data rates. Included
in the device, is a fully integrated Clock Multiplier Unit (CMU)
that is capable of generating frequencies that cover the
same data rate range as the CDR. The device is ideally
suited for SONET/SDH/ATM, Fibre Channel, and Gigabit
Ethernet applications, as well as other high-speed data
transmission applications.
Clock recovery and data retiming is performed by
synchronizing the on-chip VCO directly to the incoming data
stream. The VCO center frequency is controlled by the
reference clock frequency and the selected divide ratio.
On-chip clock generation is performed through the use of a
frequency multiplier PLL with a byte rate or code group rate
source as reference.
