Si52111-B4

PCI Express 1-Output Clock Generator Si52111-B4

Please note: Si52111-B4 is being discontinued and is not recommended for new designs.

The Si52111-B4 1-output PCIe Gen1 Clock Generator provides industry-leading jitter performance, compliance with PCI Express (PCIe) Gen 1/2/3 requirements, outstanding frequency flexibility and configurable AC parameters for signal integrity optimization. The Si52111-B4 meets PCIe Gen1,2,3 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.
