PCI Express Clock Fanout Buffer Si53102-A2

The Si53102-A2 is a PCI Express Gen 1/2/3/4/5 1 : 2 fanout buffer that meets all of the performance requirements of the Intel DB1900Z specification. The device is optimized for distributing 1 reference clock for Intel® UltraPath and QuickPath Interconnect (Intel UPI/QPI), PCIe Gen 1/2/3/4/5 , SAS, SATA and Intel Scalable Memory Interconnect (Intel SMI) applications. Each differential output can be enabled through individual hardware pins for maximum flexibility and power savings.

ClockBuilder Pro Field Programmer

When used with ClockBuilder Pro software, the ClockBuilder Pro Field Programmer makes it simple for systems designers to develop, program, and debug any Si5332/8, Si5350/1/6/7, Si534x/6x/8x/9x, Si540x, and Si55xx part families clock device “in-system,” or in one of the convenient QFN sockets. The field programmer supports I2C or SPI interfaces to the host system, and SPI to the field programmer's QFN socket boards.
