4 O/P 1.5V PCIe Gen1-2-3 ZDB/FOB
9DBU0431
DATASHEET
Description
The 9DBU0431 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. The device has 4 output enables for clock
management, and 3 selectable SMBus addresses.
Recommended Application
1.5V PCIe Gen1-2-3 Zero-Delay/Fan-out Buffer (ZDB/FOB)
Output Features
• 4 – 1-167MHz Low-Power (LP) HCSL DIF pairs
Key Specifications
• DIF cycle-to-cycle jitter <50ps
• DIF output-to-output skew <50ps
• 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
Features/Benefits
• LP-HCSL outputs; save 8 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
• slew rate for each output
• differential output amplitude
• 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

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9DBU0431. 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.
