Si53112

Si53112 PCIe Fanout/Zero-Delay Buffer

The Si53112 is a 1 : 12 PCIe Fanout/Zero-Delay Buffer that meets all of the performance requirements of the Intel DB1900Z specification. The device is optimized for distributing 12  reference clocks for Intel® QuickPath Interconnect (Intel QPI), PCIe Gen 1/Gen 2/ Gen 3, 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.

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.
