5-output 1.8V HCSL Fanout Buffer
9DBV0531
DATASHEET
Description
The 9DBV0531 is a member of IDT's Full-Featured PCIe
family. The device has 5 output enables for clock
management, and 3 selectable SMBus addresses.
Recommended Application
PCIe Gen1-3 clock distribution in Storage, Networking,
Computing, Consumer
Output Features
5 - 1-200MHz Low-Power (LP) HCSL DIF pairs
Easy AC-coupling to other logic families, see IDT
application note AN-891
Key Specifications
Additive cycle-to-cycle jitter <5ps
Output-to-output skew < 50ps
Additive phase jitter is <100fs rms for PCIe Gen3
Additive phase jitter <300fs rms (12kHz-20MHz @125MHz)
Features/Benefits
LP-HCSL outputs; save 10 resistors and 17mm2 compared
to standard HCSL
50mW typical power consumption; eliminates thermal
concerns
OE# pin for each output; support DIF power management
HCSL differential input; can be driven by common clock
sources
Spread Spectrum tolerant; allows reduction of EMI
SMBus-selectable features allow optimization to customer
requirements
Slew rate for each output; allows tuning for various line
lengths
Differential output amplitude; allows tuning for various
application environments
1MHz to 200MHz operating frequency
3.3V tolerant SMBus interface works with legacy controllers
Selectable SMBus addresses; multiple devices can easily
share an SMBus segment
Device contains default configuration; SMBus interface not
required for device operation
Space saving 32-pin 5x5mm VFQFPN; minimal board
space
