5 O/P 1.5V PCIe Gen1-2-3 Fan-out Buffer
9DBU0531
DATASHEET
Description
The 9DBU0531 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. The device has 5 output enables for clock
management, and 3 selectable SMBus addresses.
Recommended Application
1.5V PCIe Gen1-2-3 Fan-out Buffer (FOB)
Output Features
⢠5 - 1-167MHz Low-Power (LP) HCSL DIF pairs
Key Specifications
⢠DIF additive cycle-to-cycle jitter <5ps
⢠DIF output-to-output skew <60ps
⢠DIF additive phase jitter is <300fs rms for PCIe Gen3
⢠DIF additive phase jitter <350s rms for SGMII
Features/Benefits
⢠LP-HCSL outputs; save 10 resistors compared to standard
HCSL outputs
⢠35mW typical power consumption; eliminates thermal
concerns
⢠Spread Spectrum (SS) compatible; allows SS for EMI
reduction
⢠OE# pins for each output; support DIF power management
⢠HCSL-compatible differential input; can be driven by
common clock sources
⢠Spread Spectrum tolerant; allows reduction of EMI
⢠SMBus-selectable features; optimize signal integrity to
application
⢠slew rate for each output
⢠differential output amplitude
⢠Device contains default configuration; SMBus interface not
required for device operation
⢠3.3V tolerant SMBus interface works with legacy controllers
⢠3 selectable SMBus addresses; multiple devices can easily
share an SMBus segment
⢠Space saving 32-pin 5x5mm VFQFPN; minimal board
space
