PI6CBE33085
Low-Power 8-Output ZDB / Fanout Clock Buffer for PCIe 6.0 and UPI
Description
Features
e DIODES PI6CBE33085 is a low-power PCIe® 1.0/2.0/3.0/ yꢀEight Differential Low-Power HCSL Outputs with On-Chip
4.0/5.0/6.0 clock buffer. It takes a reference input to fanout eight Termination
100MHz low-power differential HCSL outputs with on-chip yꢀDefault Z
= 85Ω
OUT
terminations for 85Ω output impedance. It supports both zero- yꢀSpread Spectrum Tolerant
delay and fanout buffer functions for various applications. An yꢀIndividual Output Enable
individual OE pin for each output provides easier power man- yꢀSelectable PLL Bandwidths
agement.
yꢀHardware/SMBus Control of ZDB and Fanout Buffer Modes
It uses Diodes proprietary PLL design to achieve very-low jitter yꢀ1 to 400MHz Fanout Buffer Operation
that meets PCIe 1.0/2.0/3.0/4.0/5.0/6.0 requirements. Other than yꢀ100MHz and 133.33MHz ZDB Mode
PCIe 100MHz support, this device also supports 133.33MHz via yꢀDifferential Output-to-output Skew <50ps
a pin.
