15-output DB1900Z Low-Power Derivative
9ZXL1550
DATASHEET
Description
The 9ZXL1550 is a DB1900Z derivative buffer utilizing
Low-Power HCSL (LP-HCSL) outputs to increase edge rates
on long traces, reduce board space, and reduce power
consumption more than 50% from the original 9ZX21501. It is
pin-compatible to the 9ZXL1530 and has the output
terminations integrated. 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: <75ps
• Input-to-output delay variation: <50ps
• Phase jitter: PCIe Gen3 < 1ps rms
• Phase jitter: QPI 9.6GB/s < 0.2ps rms
Block Diagram
Features/Benefits
• LP-HCSL outputs; up to 90% IO power reduction, better
signal integrity over long traces
• Direct connect to 85Ω transmission lines; eliminates 60
termination resistors, saves 103mm2 area
• Pin compatible to the 9ZXL1530; easy upgrade to reduced
board space
• 64-VFQFPN package; smallest 15 output Z-buffer
• 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
• 100MHz & 133.33MHz PLL mode; legacy QPI/UPI support
• 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
Output Features
• 15 - LP-HCSL Differential Output Pairs w/integrated
terminations (Zo = 85)

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.
