Overview
4 to 12-Output Buffers for PCIe Gen1–5 and UPI 9ZXL04x1E/9ZXL06x1E/ 9ZXL08x1E/9ZXL12x1E Datasheet Description The 9ZXL04x1E/9ZXL06x1E/9ZXL08x1E/9ZXL12x1E family of Zero-Delay/Fanout Buffers (ZDB, FOB) are 2nd-generation enhanced performance buffers for PCIe and CPU applications.
The family meets all published QPI/UPI, DB2000Q and PCIe Gen1–5 jitter specifications.
Devices range from 4 to 12 outputs, with each output having an OE# pin to support the PCIe CLKREQ# function for low power states.
All devices meet DB2000Q, DB1200ZL and DB800ZL jitter and skew requirements.
PCIe Clocking Architectures ▪ Common Clocked (CC) ▪ Independent Reference (IR) with and without spread spectrum (SRIS, SRNS) Key Specifications ▪ Fanout Buffer Mode additive phase jitter: • PCIe Gen5 CC < 24fs RMS • DB2000Q additive jitter < 40fs RMS • QPI/UPI 11.
4GB/s < 40fs RMS • IF-UPI additive jitter < 70fs RMS ▪ ZDB Mode phase jitter: • PCIe Gen5 CC < 22fs RMS • QPI/UPI 11.
4GB/s < 120fs RMS • IF-UPI additive jitter < 130fs RMS ▪ Cycle-to-cycle jitter < 50ps ▪ Output-to-output skew < 50 ps Block Diagram VDDR VDDA Features ▪ 4–12 Low-power HCSL (LP-HCSL) outputs ▪ Integrated terminations eliminate up to 4 resistors per output pair ▪ Dedicated OE# pins support PCIe CLKREQ# function ▪ Up to 9 selectable SMBus addresses (9ZXL12) ▪ Selectable PLL bandwidths minimizes jitter peaking in cascaded PLL topologies ▪ Hardware/SMBus control of ZDB and FOB modes ▪ Spread-spectrum compatible ▪ 1–400MHz FOB operation (all devices) ▪ 100MHz and 133.
33MHz ZDB mode (9ZXL12, 9ZXL08) ▪ 100MHz ZDB mode (9ZXL06, 9ZXL04) ▪ -40°C to +85°C operating temperature range (all devices) ▪ -40°C to +105°C operating temperature range (9ZXL08) ▪ Package information: see Ordering Information for details Applications ▪ Servers/High-performance Computing ▪ nVME Storage ▪ Networking ▪ Accelerators ▪ Industrial Control VDD VDDIO (9ZXL12x1 only) 9ZXL12x1 9ZXL08x1 only 9ZXL12x1 only 9ZXL12x1 9ZXL0451 only DIF_IN# DIF_IN ^100M_13...
