The Renesas Electronics PCIE ZDB/FO-BUFFER GEN1-2-3 is an 8-output very low power buffer for 100MHz PCIe Gen1–5 applications. It can also be used for 50M or 125M Ethernet applications via software frequency selection. The device has 8 output enables for clock management, and 3 selectable SMBus addresses.

1.8V operation minimal power consumption
Outputs can optionally be supplied from any voltage between 1.05V and 1.8V
OE pins support DIF power management
HCSL compatible differential input can be driven by common clock sources
LP-HCSL differential clock outputs reduced power and board space
