Low-Power 4-Output ZDB / Fanout Clock Buffer for PCIe 6.0 and UPI
Description
Features
yꢀFour Differential Low-Power HCSL Outputs with On-Chip
e DIODES PI6CBE33045 is a low-power PCIe® 1.0/2.0/3.0/
4.0/5.0/6.0 clock buffer. It takes a reference input to fanout four

minations for 85Ω output impedance. It supports both zero-delay
and fanout buffer functions for various applications. An individ-
ual OE pin for each output provides easier power management.
It uses Diodes proprietary PLL design to achieve very-low jitter
that meets PCIe 1.0/2.0/3.0/4.0/5.0/6.0 requirements.
