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.
