9ZXL0831E

8-Output DB800ZL for PCIe Gen1–4 and QPI/UPI 9ZXL0831E / 9ZXL0851E Datasheet Description The 9ZXL0831E / 9ZXL0851E are second-generation enhanced performance DB800ZL differential buffers. The parts are pin-compatible upgrades to the 9ZXL0831A and 9ZXL0851A, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications. PCIe Clocking Architectures Supported ▪ Common Clocked (CC) ▪ Independent Reference (IR) with and without spread spectrum Typical Application ▪ Servers ▪ Storage ▪ Networking ▪ SSDs Output Features ▪ 8 Low-Power (LP) HCSL output pairs (0831E) ▪ 8 Low-Power (LP) HCSL output pairs with 85Ω Zout (0851E) Features ▪ LP-HCSL outputs; eliminate 16 resistors, save 27mm2 of area (0831E) ▪ LP-HCSL outputs with 85Ω Zout; eliminate 32 resistors, save 64mm2 of area (0851E) ▪ 8 OE# pins; hardware control of each output ▪ Selectable PLL BW; minimizes jitter peaking in cascaded PL...
