709 OTN custom FEC  Carrier Ethernet, multi-service  10/40/100G switches and routers  OC-48/192, STM-16/64  MSPP, ROADM, P-OTS, muxponders Description The Si5376 is a highly-integrated, 4-PLL, jitter-attenuating precision clock multiplier for applications requiring sub-1 ps jitter performance.
Each of the DSPLL® clock multiplier engines accepts two input clocks ranging from 2 kHz to 710 MHz and generates two independent synchronous output clocks ranging from 2 kHz to 808 MHz.
The device provides virtually any frequency translation combination across this operating range.
For asynchronous, free-running clock generation applications, the Si5376’s reference oscillator can be used as a clock ...
