Si52112-B3 & Si52112-B4 PCIe Clock Generators

Skyworks Solutions Inc. Si52112-B3 and Si52112-B4 PCIe Clock Generators provide industry-leading jitter performance compliant with PCI Express (PCIe) Gen 1 and Gen 2 requirements. The Si52112-B3 and Si52112-B4 can source two PCIe clocks from a 25MHz crystal or clock input. These devices offer outstanding frequency flexibility and configurable AC parameters for signal integrity optimization. The use of push-pull HCSL outputs ensures low power consumption and no external termination resistors are required, saving board space.
