描述 Description

The 6P41282 is a member of Renesas’ SOC-Friendly 1.8V

very low-power PCIe clock family. The device has integrated

100? output terminations providing direction connection to

100? transmission lines. The device also has 6 output

enables for clock management and supports 2 different

spread spectrum levels in addition to spread off.

特性 Features

? LP-HCSL outputs with integrated terminations; save 24

resistors compared to standard PCIe devices

? 54mW typical power consumption; reduced thermal

concerns

? Outputs can optionally be supplied from any voltage

between 1.05V and 1.8V; maximum power savings

? OE# pins; support DIF power management

? 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

? Selectable SMBus addresses; multiple devices can easily

share an SMBus segment

? Space saving 5 x 5 mm 40-VFQFPN; minimal board space
