IDT, Integrated Device Technology Inc 9DBU0441AKILF

Description
The 9DBU0441 is a member of IDT's 1.5V Ultra-Low-Power (ULP) PCIe family. It features integrated output terminations providing Zo=100Ω for direct connection to 100Ω transmission lines. The device has 4 output enables for clock management and 3 selectable SMBus addresses.

Features
4-1-167MHz Low-Power (LP) HCSL DIF pairs w/ ZO=1000Ω
DIF cycle-to-cycle jitter <50ps
DIF output-to-output skew <75ps
DIF phase jitter is PCIe Gen 1-2-3 compliant
DIF bypass mode additive phase jitter is <300fs rms for PCIe Gen3
DIF bypass mode additive phase jitter <350fs rms for 12k-20MHz
Direct connection to 100Ω transmission lines; saves 16 resistors compared to standard HCSL outputs
45mW typical power consumption in PLL mode; eliminates thermal concerns
Spread Spectrum (SS) compatible; allows SS for EMI reduction
OE# pins; support DIF power management
HCSL-compatible differential input; can be driven by common clock sources
SMBus-selectable features; optimize signal integrity to application
Pin/software selectable PLL bandwidth and PLL Bypass; optimize PLL to application
Outputs blocked until PLL is locked; clean system start-up
Device contains default configuration; SMBus interface not required for device control
3.3V tolerant SMBus interface works with legacy controllers
Three selectable SMBus addresses; multiple devices can easily share an SMBus segment
Space saving 32-pin 5x5mm VFQFPN; minimal board space

Applications
1.5V PCIe Gen1-2-3 Zero-Delay/Fan-out Buffer (ZDB/FOB)
