Si5321 Datasheet (Silicon Laboratories) - SONET/SDH PRECISION CLOCK MULTIPLIER IC

Si5321, SONET/SDH PRECISION CLOCK MULTIPLIER IC

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 o

Si5321 Features

* Ultra-low jitter clock output with jitter

* Digital hold for loss-of-input clock generation as low as 0.3 psRMS

* Support for 255/238 (15/14),

* No external components (other than a 255/237 (85/79), and 66/64 FEC scaling resistor and bypassing) (ITU-T G.709 and IEEE 802.3ae)
