DATASHEET
Description
The 9ZX21501 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 9ZX21501 can provide outputs up to 400MHz.
Key Specifications
Cycle-to-cycle jitter: < 50ps
Output-to-output skew: <65ps
Input-to-output delay: 0 ps fixed
Input-to-output delay variation: <50ps
Phase jitter: PCIe Gen3 < 1ps rms
Phase jitter: QPI 9.6GB/s < 0.2ps rms
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
