描述 Description

The IDT6P61043 is a 4-output very low power buffer for

100MHz PCIe Gen1, Gen2 and Gen3 applications with

integrated output terminations providing Zo=100?. The

device has 4 output enables for clock management, and 3

selectable SMBus addresses.

Features/Benefits

? Integrated terminations provide 100? differential Zo;

reduced component count and board space

? 1.8V operation; minimal power consumption

? 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

? Programmable Slew rate for each output; allows tuning

for various line lengths

? Programmable output amplitude; allows tuning for

various application environments

? Pin/software selectable PLL bandwidth and PLL Bypass;

minimize phase jitter for each application

? Outputs blocked until PLL is locked; clean system

start-up

? Software selectable 50MHz or 125MHz PLL operation;

useful for Ethernet applications

? Configuration can be accomplished with strapping pins;

SMBus interface not required for device control

? 3.3V tolerant SMBus interface works with legacy

controllers

? Space saving 32-pin 5x5mm MLF; minimal board space

? Selectable SMBus addresses; multiple devices can

easily share an SMBus segment
