19-Output DB1900Z for PCIe Gen1-4 and  
QPI/UPI  
9ZX21901D  
DATASHEET  
Description  
Features  
The 9ZX21901D is a second generation DB1900Z differential  
buffer for Intel Purley and newer platforms. The part is  
backwards compatible to the 9ZX21901C while offering much  
improved phase jitter performance. A fixed external feedback  
maintains low drift for critical QPI/UPI applications. In bypass  
mode, the 9ZX21901D can provide outputs up to 400MHz.  
Fixed feedback path; 0ps input-to-output delay  
9 Selectable SMBus addresses; multiple devices can share  
same SMBus segment  
8 dedicated OE# pins; hardware control of outputs  
PLL or bypass mode; PLL can dejitter incoming clock  
Selectable PLL BW; minimizes jitter peaking in downstream  
PLL's  
PCIe Clocking Architectures Supported  
Common Clocked (CC)  
Separate Reference No Spread (SRNS)  
Separate Reference Independent Spread (SRIS)  
Hardware or software control of PLL operating mode;  
change mode with software mode does not need power  
cycle  
Spread spectrum compatible; tracks spreading input clock  
for EMI reduction  
Typical Applications  
Servers, Storage, Networking  
SMBus Interface; unused outputs can be disabled  
100MHz and 133.33MHz PLL mode; legacy QPI support  
72-QFN 10 x 10 mm package; small board footprint  
Output Features  
19 HCSL output pairs  
Key Specifications  
Cycle-to-cycle jitter: < 50ps  
Output-to-output skew: < 50ps  
Input-to-output delay: Fixed at 0 ps  
Input-to-output delay variation: < 50ps  
Phase jitter: PCIe Gen4 < 0.5ps rms  
Phase jitter: UPI 9.6GB/s < 0.1ps rms
