The 9DBL0255/9DBL0455 are 2 and 4-output PCIe Clock fan-out buffers for PCIe Gen1–5 applications.

Both parts have an open drain Loss of Signal (LOS) output to indicate the absence or presence of an input clock.

The LOS circuit also implements Automatic Clock Parking (ACP) to cleanly park the outputs low/low when the input clock goes away.

to aid robust designs. Flexible Power Sequencing (FPS) ensures well-defined behavior under various power up scenarios, while Power Down Tolerant (PDT) ESD protection allows input pins to be driven before VDD is applied. The 9DBL0255/9DBL0455 are spread-spectrum compatible and provide direct connection to 85Ω transmission lines. They can also be used in 100Ω environments with simple external series resistors.
