19-OUTPUT DB1900Z LOW-POWER DERIVATIVE  
9ZXL1930  
Description  
Features/Benefits  
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.  
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  
Recommended Application  
Buffer for Romley, Grantley and Purley Servers  
Spread spectrum compatible; tracks spreading input  
clock for EMI reduction  
SMBus Interface; unused outputs can be disabled  
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  
100MHz & 133.33MHz PLL mode; Legacy QPI/UPI  
support  
Differential outputs are Low/Low in power down;  
Maximum power savings

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.

trace impedance).  
2 Measured from differential waveform  
3 Slew rate is measured through the Vswing voltage range centered around differential 0V. This results in a +/-150mV window around  
differential 0V.  
4 Matching applies to rising edge rate for Clock and falling edge rate for Clock#. It is measured using a +/-75mV window centered on  
the average cross point where Clock rising meets Clock# falling. The median cross point is used to calculate the voltage thresholds the  
oscilloscope is to use for the edge rate calculations.  
5 Vcross is defined as voltage where Clock = Clock# measured on a component test board and only applies to the differential rising  
edge (i.e. Clock rising and Clock# falling).  
6 The total variation of all Vcross measurements in any particular system. Note that this is a subset of Vcross_min/max (Vcross  
absolute) allowed. The intent is to limit Vcross induced modulation by setting -Vcross to be smaller than Vcross absolute.

Notes for preceding table:  
1
Measured into fixed 2 pF load cap. Input to output skew is measured at the first output edge following the corresponding input.  
Measured from differential cross-point to differential cross-point. This parameter can be tuned with external feedback path, if present.  
All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it.  
2
3
4 This parameter is deterministic for a given device  
5
Measured with scope averaging on to find mean value.  
6. t is the period of the input clock  
7 Measured as maximum pass band gain. At frequencies within the loop BW, highest point of magnification is called PLL jitter peaking.  
8.  
Guaranteed by design and characterization, not 100% tested in production.  
9
Measured at 3 db down or half power point.  
10 Duty cycle distortion is the difference in duty cycle between the output and the input clock when the device is operated in bypass mode.  
11 Measured from differential waveform
