Skyworks Solutions Inc. Si522xx PCIe Clock Generators

Skyworks Si522xx PCIe Clock Generators Gen 1/2/3/4 designed for highest performance and lowest power PCI-Express clock generators for 1.5V to 1.8V power supply. These clock generators feature individual hardware control pins for enabling and disabling each output and spread spectrum for EMI reduction. The clock generators offer 133MHz or 200MHz differential output frequencies which can also be controlled via I2C.

The Skyworks Si52212, Si52208, Si52204 can source twelve, eight, and four 100MHz PCIe differential clock outputs with plus one 25MHz LVCMOS reference clock output. The Si52202 can source two 100MHZ PCIe clock outputs only. These clock generators are ideal for industrial and consumer applications for small footprints and low power consumption. Other applications include servers, storage, data centers, dock stations, digital video cameras, and multi-function printers.
