9ZXL0451E, 4-Output DB800ZL Derivative

4-Output DB800ZL Derivative for PCIe Gen1 *5, UPI and DB2000Q 9ZXL0451E Datasheet .
The 9ZXL0451E is a second generation enhanced performance DB800ZL derivative for PCIe Gen4 and 5 applications.

Features

* ▪ 4 Low-power HCSL (LP-HCSL) output pairs with 85Ω Zout Features ▪ LP-HCSL outputs eliminate 16 resistors; save 32mm2 of area ▪ 4 OE# pins; SMBus control also available ▪ 3 selectable SMBus addresses ▪ 2 selectable ZDB bandwidths; minimizes jitter peaking in cascaded PLL topologies ▪ Hardware/SMBus

Applications

* In fanout (bypass) mode, it is DB2000Q compatible. A fixed external feedback in ZDB mode maintains low drift for critical QPI/UPI applications. PCIe Clocking Architectures Supported ▪ Common Clocked (CC) ▪ Independent Reference (IR) with and without spread spectrum Typical Applications ▪ Servers ▪
