PCIe® Clock Buffers and Generators

Renesas offers PCIe Gen1-4 clock generation for riser cards, storage, networking, JBOD, communications, and access points with its 9DBL0x and 9FGL0x devices

Image of Renesas’ PCIe® Clock Generators and BuffersRenesas’ 9DBL0x PCIe clock buffer devices are 3.3 V members of Renesas’ full-featured PCIe family. The 9DBL0x support PCIe Gen1-4 common clocked (CC) and PCIe separate reference independent spread (SRIS) systems. They offer a choice of integrated output terminations providing direct connection to 85 Ω or 100 Ω transmission lines.

Renesas’ 9FGL0x PCIe clock generator devices are also, 3.3 V members of Renesas’ 3.3 V full-featured PCIe family. The devices have 2-, 4-, 6-, and 8-output enables for clock management and support two different spread spectrum levels in addition to spread off. The 9FGL0x supports PCIe Gen1-4 common clocked architectures (CC) and PCIe separate reference no-spread (SRnS) and separate reference independent spread (SRIS) clocking architectures.

The 9DBL0xP1 and 9FGL0xP1 devices can be factory programmed with a user-defined power up default SMBus configuration.

PCIe Clock Buffer's Features
