5-Output 1.5V PCIe Gen1-2-3 Fanout Buffer
with Zo=100ohms
9DBU0541
DATASHEET
Description
The 9DBU0541 is a member of IDT's 1.5V Ultra-Low-Power
(ULP) PCIe family. It has integrated terminations for direct
connection to 100ï transmission lines. The device has 5
output enables for clock management, and 3 selectable
SMBus addresses.
Recommended Application
1.5V PCIe Gen1-2-3 Fanout Buffer (FOB)
Output Features
⢠5 1â167MHz Low-Power (LP) HCSL DIF pairs with
ZO=100ï
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 < 350fs rms for SGMII
Features/Benefits
⢠Integrated terminations; save 20 resistors compared to
standard HCSL outputs
⢠35mW typical power consumption; 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
⢠Device contains default configuration; SMBus interface not
required for device control
⢠3.3V tolerant SMBus interface works with legacy controllers
⢠Selectable SMBus addresses; multiple devices can easily
share an SMBus segment
⢠5 à 5 mm 32-VFQFPN; minimal board space
