SI5320 SONET/SDH PRECISION CLOCK MULTIPLIER IC

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 .

Features

 Ultra-low-jitter clock output with jitter generation as low as 0.3 psRMS
 No external components (other than a resistor and standard bypassing)
 Input clock ranges at 19, 39, 78, 155, 311, and 622 MHz
 Output clock ranges at 19, 155, or 622 MHz
 Digital hold for loss of input clock
 Support for forward and reverse FEC clock scaling
 Selectable loop bandwidth
 Loss-of-signal alarm output
 Low power
 Small size (9x9 mm) Applications
 SONET/SDH line/port cards
 Optical modules
 Core switches
 Digital cross connects
 Terabit routers Description The Si5320 is a precision clock.
