2 O/P 1.5V PCIe Gen1-2-3 Clock Generator

9FGU0231

Description

The 9FGU0231 is a member of IDT's 1.5V Ultra-Low-Power

PCIe clock family. The device has 2output enables for clock

management, 2 different spread spectrum levels in addition to

spread off and 2 selectable SMBus addresses.

Recommended Application

1.5V PCIe Gen1-2-3 clock generator

Output Features

• 2 - 100MHz Low-Power (LP) HCSL DIF pairs

• 1 - 1.5V LVCMOS REF output w/Wake-On-LAN (WOL)

support

Key Specifications

• DIF cycle-to-cycle jitter <50ps

• DIF output-to-output skew <50ps

• DIF phase jitter is PCIe Gen1-2-3 compliant

• REF phase jitter is < 3.0ps RMS

Features/Benefits

• LP-HCSL outputs; save 4 resistors compared to standard

PCIe devices

• 23mW typical power consumption; reduced thermal

concerns

• 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

• Selectable SMBus addresses; multiple devices can easily

share an SMBus segment

• 3.3V tolerant SMBus interface works with legacy controllers

• Space saving 24-pin 4x4 mm VFQFPN; minimal board

space
