DATASHEET
FIFTEEN OUTPUT DIFFERENTIAL ZBUFFER FOR PCIE GEN2/3 AND QPI
9ZX21501C
Description
The 9ZX21501C is a 15-output version of the Intel
DB1900Z Differential Buffer suitable for PCI-Express Gen3
or QPI applications. The part is backwards compatible to
PCIe Gen1 and Gen2. A fixed external feedback maintains
low drift for critical QPI applications. In bypass mode, the
9ZX21501C can provide outputs up to 400MHz.
Recommended Application
15-output PCIe Gen3/QPI buffer with fixed feedback for
Romley platforms
Output Features
15 - 0.7V current mode differential HCSL output pairs
Features/Benefits
Fixed feedback path; 0ps input-to-output delay
9 Selectable SMBus addresses; multiple devices can
share same SMBus segment
7 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
Spread spectrum compatible; tracks spreading input
clock for EMI reduction
SMBus Interface; unused outputs can be disabled
100MHz & 133.33MHz PLL mode; legacy QPI support
Undriven differential outputs in Power Down mode for
maximum power savings
