描述 Description

The 6P41302 is an 8-output very low power clock generator

for PCIe Gen1-2-3 applications with integrated output

terminations providing Zo = 100?. The device has 8 output

enables for clock management and supports 2 different

spread spectrum levels in addition to spread off.

特性 Features

? Integrated terminations provide 100? differential Zo;

reduced component count and board space

? 1.8V operation; reduced power consumption

? Outputs can optionally be supplied from any voltage

between 1.05V and 1.8V; maximum power savings

? OE# pins; support DIF power management

? 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

? DIF outputs blocked until PLL is locked; clean system

start-up

? Selectable 0, -0.25 or -0.5 spread on DIF outputs;

reduces EMI

? External 25MHz crystal; supports tight ppm with 0 ppm

synthesis error

? 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 6 x 6 mm 48-VFQFPN; minimal board

space

? Selectable SMBus addresses; multiple devices can

easily share an SMBus segment
