Diodes Incorporated PI6CB18200 Low-Power 2-Output PCIe Clock Buffers

Diodes Incorporated PI6CB18200 Low-Power 2-output Clock Buffer achieves very low jitter and meets PCIe Gen1 / Gen2 / Gen3 requirements. This device offers a reference input to fan out two 100MHz low-power differential HCSL outputs. Designed with an individual OE pin for each output, the PI6CB18200 offers flexible power management options to optimize the performance of an individual board. These options include programmable slew rate and output amplitude for each output. Diodes Incorporated PI6CB18200 supports PCIe 100MHz and 50MHz or 125MHz Ethernet applications through an SMBus. Applications include blade servers, base stations, PCs, security, routers, and switches.
