Si5320
SONET/SDH PRECISION CLOCK MULTIPLIER IC
Features
Applications
Description
The Si5320 is a precision clock multiplier designed to exceed the requirements of
high-speed communication systems, including OC-192/OC-48 and 10 GbE. 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, 155, or 622 MHz range. Silicon Laboratories’
DSPLL technology delivers all PLL functionality with unparalleled performance
while eliminating external loop filter components, providing programmable loop
parameters, and simplifying design. FEC rates are supported with selectable 255/
238 or 238/255 scaling of the clock multiplication ratios. The Si5320 establishes a
new standard in performance and integration for ultra-low-jitter clock generation. It
operates from a single 3.3 V supply.
