Si5321
SONET/SDH PRECISION CLOCK MULTIPLIER IC
Features
Applications
Description
The Si5321 is a precision clock multiplier that exceeds the requirements of high-speed
communication systems, including OC-192/OC-48 and 10 Gigabit Ethernet. This device
phase locks to an input clock in the 19, 39, 78, 155, 311 or 622 MHz frequency range
and generates a frequency-multiplied clock output that can be configured for operation
in the 19, 39, 78, 155, 622, 1244, or 2488 MHz frequency range. Silicon Laboratories
DSPLL technology provides PLL functionality with unparalleled performance. It
eliminates external loop filter components, provides programmable loop parameters,
and simplifies design. FEC rates are supported by selectable forward and reverse 255/
238 (15/14), 255/237 (85/79), and 66/64 (33/32) conversion factors. The ITU-T G.709
255/237 rate and the IEEE 802.3ae 66/64 rate are supported when using a 155 MHz or
higher rate input clock. The performance and integration of Silicon Laboratories’ Si5321
clock IC provides high-level support of the latest specifications and systems. It operates
from a single 3.3 V supply.
