6-output 3.3V PCIe Zero-Delay  
Buffer  
9DBL0641 / 9DBL0651  
DATASHEET  
Description  
Features/Benefits  
The 9DBL0641 / 9DBL0651 devices are 3.3V members of  
IDT's Full-Featured PCIe family. The 9DBL06 supports PCIe  
Gen1-4 Common Clocked (CC) and PCIe Separate  
Reference Independent Spread (SRIS) systems. It offers a  
choice of integrated output terminations providing direct  
connection to 85or 100transmission lines. The  
9DBL06P1 can be factory programmed with a user-defined  
power up default SMBus configuration.  
Direct connection to 100(xx41) or 85(xx51)  
transmission lines; saves 24 resistors compared to  
standard PCIe devices  
149mW typical power consumption (PLL mode@3.3V);  
eliminates thermal concerns  
VDDIO allows 30% power savings at optional 1.05V;  
maximum power savings  
SMBus-selectable features allows optimization to customer  
requirements:  
Recommended Application  
PCIe Gen1-4 clock distribution for Riser Cards, Storage,  
Networking, JBOD, Communications, Access Points  
control input polarity  
control input pull up/downs  
– slew rate for each output  
Output Features  
6 – 1-200 MHz Low-Power (LP) HCSL DIF pairs  
9DBL0641 default ZOUT = 100  
– differential output amplitude  
– output impedance for each output  
– 50, 100, 125MHz operating frequency  
9DBL0651 default ZOUT = 85  
9DBL06P1 factory programmable defaults  
Customer defined SMBus power up default can be  
programmed into P1 device; allows exact optimization to  
customer requirements  
Key Specifications  
OE# pins; support DIF power management  
PCIe Gen1-2-3-4 CC compliant in ZDB mode  
PCIe Gen2 SRIS compliant in ZDB mode  
Supports PCIe Gen2-3 SRIS in fan-out mode  
DIF cycle-to-cycle jitter <50ps  
DIF output-to-output skew < 50ps  
Bypass mode additive phase jitter is 0 ps typical rms for  
PCIe  
HCSL-compatible differential input; can be driven by  
common clock sources  
Spread Spectrum tolerant; allows reduction of EMI  
Pin/SMBus selectable PLL bandwidth and PLL Bypass;  
minimize phase jitter for each application  
Outputs blocked until PLL is locked; clean system start-up  
Device contains default configuration; SMBus interface not  
required for device operation  
Bypass mode additive phase jitter 160fs rms typ. @  
156.25M (1.5M to 10M)  
Three selectable SMBus addresses; multiple devices can  
easily share an SMBus segment  
Space saving 40-pin 5x5mm VFQFPN; minimal board  
space  
Block Diagram  
Note: Default resistors are internal on xx41/xx51 devices. P1 devices have programmable default impedances on an output-by-output basis.
