Silicon Labs Si53119-EK, Clock Buffer Evaluation Board for Si53119, Оценочная плата

Evaluation board for Si53119, 19 Output PCIe Clock Buffer, Silicon Laboratories

The Si53119-EK by Silicon Laboratories is a PCIe clock & development kit that offers a high performance level per watt for clocking applications necessary to meet PCI Express® Gen1/2/3 standards. These clock generators and buffers have two times lower power and are able to provide up to 50% margin to PCI-Express jitter specifications. Silicon Labs Si53119-EK PCIe Clock Generators and Buffers fully integrate termination resistors, reduce BOM cost, board space requirements and design complexity.

The Si53119 is a 19-output, low-power HCSL differential clock buffer that meets all of the performance requirements of the Intel DB1200ZL specification.
