Features

Applications

Description

The Si53115 is a 15-output, low-power HCSL differential clock buffer that

meets all of the performance requirements of the Intel DB1200ZL

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 can be enabled through I2C

for maximum flexibility and power savings. Measuring PCIe clock jitter is

quick and easy with the Silicon Labs PCIe Clock Jitter Tool. Download it
