Description

The IDT6P61033 is an 8-output very low power buffer for

100MHz PCIe Gen1, Gen2 and Gen3 applications with

integrated output terminations providing Zo=100. The

device has 8 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

• Outputs can optionally be supplied from any voltage

between 1.05 and 1.8V; maximum power savings

• 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 48-pin 6x6mm VFQFPN; minimal board

space

• Selectable SMBus addresses; multiple devices can

easily share an SMBus segment
