9DBL0455 - 2 and 4-Output 3.3V PCIe Gen1-5 Clock Fanout Buffers
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

* 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 connecti
