Automotive PCI Express (PCIe) Clock Generators

Our PCI Express Gen1/2/3/4/5 devices are the highest performance, lowest power clock generators on the market. All devices feature low-power push-pull output buffer technology, providing benefits of low-power consumption, reduced external terminating resistors and smaller packaging. To optimize performance, PCI Express Gen1/2/3/4/5 clock generators support programmable drive strength, rise/fall times and output impedance, as well as down spread spectrum clock generation. The devices support the standard PCIe HCSL signaling format and can be externally terminated to support LVPECL, LVDS or CML levels.
