Product Details
This highly flexible architecture is capable of synthesizing a wide range of both integer and non-integer related frequencies up to 1 GHz on 12 differential clock outputs while delivering sub-100 fs rms phase jitter performance optimized for 100G/200G/400G applications. Each of the clock outputs can be assigned its own format and output voltage enabling the Si5391 to replace multiple clock ICs and oscillators with a single device, making it a true "clock tree on a chip." The Si5391 can be quickly and easily configured using ClockBuilderPro software. Custom part numbers are automatically assigned using ClockBuilder™ Pro so as to realize fast, free, and easy factory pre-programming or the Si5391 can be programmed via I2C and SPI serial interfaces.
Applications:
100/200/400G switches
56G/112G PAM4 SerDes reference clocks
Clock tree generation replacing XOs, buffers, signal format translators
Clocking for FPGAs, processors and memory
Ethernet switches/routers
OTN framers/mappers/processors
