Description
The 9DML2855 is a 2-input, 8-output clock multiplexer supporting PCIe Gen1–5 and DB2000Q applications. The device supports complex clock architecture like CC, SRIS, and SRNS while providing very low additive jitter. Flexible Power Sequencing (FPS) ensures well-defined behavior under various power-up scenarios, while Power Down Tolerant (PDT) ESD protection on all input pins allows input pins to be driven before VDD is applied. The 9DML2855 also features an OE# pin for each output and supports PCIe CLKREQ# functionality.
