PCI Express 4-Output Clock Generator Si52204-A02

The Si52204-A02 4-output PCIe Gen1 Clock Generator provides industry-leading jitter performance, compliance with PCI Express (PCIe) Gen 1/2/3/4/5/6 requirements, outstanding frequency flexibility and configurable AC parameters for signal integrity optimization. The Si52204-A01 meets PCIe Gen1,2,3,4,5,6 phase jitter requirements with margin, and is available in industrial temperature range. The use of push-pull HCSL outputs ensures the lowest power consumption, while saving board space and external termination resistors for added BOM consolidation.

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.
