6P41302NDGI8集成电路（IC）的应用特定时钟/定时规格书PDF中文资料

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
