Product Information

Back to top
The Si522xx is the industry's highest performance and lowest power PCI Express clock generator family for 1.5–1.8 V PCIe Gen1/2/3/4 and SRIS applications.

The Si52204 can source four 100 MHz PCIe differential clock outputs, plus one 25 MHz LVCMOS reference clock output. All differential clock outputs are compliant to PCIe Gen1/2/3/4 common clock and separate reference clock architectures specifications.

The Si522xx features individual hardware control pins for enabling and disabling each output, spread spectrum enable/disable for EMI reduction, and frequency select to select 133 MHz or 200 MHz differential output frequencies. These features can also be controlled via I²C.

The small footprint and low power consumption make this family of PCIe clock generators ideal for industrial and consumer applications.

Applications:
• Servers
• Storage
• Data Centers
• PCIe Add-on Cards
• Network Interface Cards (NIC)
• Graphics Adapter Cards
• Multi-function Printers
• Digital Single-Lens Reflex (DSLR) Cameras
• Digital Still Cameras
• Digital Video Cameras
• Docking Stations
