9ZXL06x2E/9ZXL08xx E/9ZXL12x2E 6 to 12-Output Buffers for PCIe Gen1- 5 and UPI with SMBus Write Protect The 9ZXL revision E family of Zero-Delay/Fanout Buffers (ZDB, FOB) with SMBus Write Protect are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The devices have hardware SMBUS write protection to prevent accidental writes. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1- 5 jitter specifications. Devices range from 6 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. Applications - Servers/High-performance puting - n VME Storage - Networking - Accelerators - Industrial Control Key Specifications - Fanout Buffer Mode additive phase jitter: - PCIe Gen5 CC, UPI > 20Gb/s < 24fs RMS - DB2000Q additive jitter < 39fs RMS - QPI/UPI 11.4GB/s < 40fs RMS - IF-UPI additive jitter < 70fs RMS - ZDB Mode phase jitter: - PCIe Gen5 CC, UPI > 20Gb/s < 22fs RMS - QPI/UPI 11.4GB/s < 120fs RMS - IF-UPI additive jitter < 130fs RMS - Cycle-to-cycle jitter < 50ps - Output-to-output skew < 50ps Features - SMBus Write Protect pin prevents SMBus against accidental writes - 6- 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 (9ZXL12xx, 9ZXL0853) - Selectable PLL bandwidths minimizes jitter peaking in cascaded PLL topologies - Hardware/SMBus control of ZDB and FOB modes allow change without power...
