6 O/P 1.5V PCIe Gen1-2-3 ZDB/FOB
w/Zo=100ohms
9DBU0641
DATASHEET
Description
The 9DBU0641 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. It has integrated output terminations
providing Zo=100for direct connection to 100
transmission lines. The device has 6 output enables for clock
management and 3 selectable SMBus addresses.
Recommended Application
1.5V PCIe Gen1-2-3 Zero Delay/Fanout Buffer (ZDB/FOB)
Output Features
6 – 1-167MHz Low-Power (LP) HCSL DIF pairs
w/Zo=100
Key Specifications
DIF cycle-to-cycle jitter <50ps
DIF output-to-output skew <60ps
DIF phase jitter is PCIe Gen1-2-3 compliant
DIF bypass mode additive phase jitter is <300fs rms for
PCIe Gen3
DIF bypass mode additive phase jitter <350fs rms for
12k-20MHz
Block Diagram
vOE(5:0)#

Features/Benefits
Direct connection to 100transmission lines; saves 24
resistors compared to standard HCSL outputs
46mW typical power consumption in PLL mode; eliminates
thermal concerns
Outputs can optionally be supplied from any voltage
between 1.05 and 1.5V; maximum power savings
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
slew rate for each output
differential output amplitude
Pin/SMBus selectable PLL bandwidth and PLL Bypass;
optimze 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 40-pin 5x5mm VFQFPN; minimal board
space

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9DBU0641. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.
