Product Information

Back to top
The Si52202-A01 2 output PCIe Gen1 Clock Generator provides industry-leading jitter performance, compliance with PCI Express (PCIe) Gen 1/2/3/4 requirements, outstanding frequency flexibility and configurable AC parameters for signal integrity optimization. The Si52202-A01 meets PCIe Gen1,2,3,4 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.
