19-OUTPUT DB1900Z LOW-POWER DERIVATIVE
DATASHEET
9ZXL1930
Description
The 9ZXL1930 is a low power version of the Intel DB1900Z
Differential Buffer utilizing Low-Power HCSL (LP-HCSL)
outputs to reduce power consumption more than 50% from
the original IDT9ZX21901. It is suitable for PCI-Express
Gen1/2/3 or QPI/UPI applications, and uses a fixed external
feedback to maintain low drift for demanding QPI/UPI
applications.
Recommended Application
Buffer for Romley, Grantley and Purley Servers
Key Specifications
Cycle-to-cycle jitter: < 50ps
Output-to-output skew: <85ps
Input-to-output delay: Fixed at 0 ps
Input-to-output delay variation: <50ps
Phase jitter: PCIe Gen3 < 1ps rms
Phase jitter: QPI/UPI 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
Separate VDDIO for outputs; allows maximum power
savings
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/UPI
support
Differential outputs are Low/Low in power down;
Maximum power savings
Output Features
19 - LP-HCSL Differential Output Pairs

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9ZXL1930. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over
the recommended operating temperature range.
