Patents pending Description The Si53108 is a low-power, 8-output, differential clock buffer that meets all of the performance requirements of the Intel DB800ZL specification. The device is optimized for distributing reference clocks for Intel® QuickPath Interconnect (Intel QPI), PCIe Gen 1/Gen 2/Gen 3/Gen 4, SAS, SATA, and Intel Scalable Memory Interconnect (Intel SMI) applications. The VCO of the device is optimized to support 100 MHz and 133 MHz operation. Each differential output has a dedicated hardware output enable pin for maximum flexibility and power savings. Measuring PCIe clock jitter is quick and easy with the Silicon Labs PCIe Clock Jitter Tool. Download it for free at www.silabs.com/pcie-learningcenter.
