9ZXL1951D

19-Output DB1900ZL Derivative for PCIe Gen1–4 and QPI/UPI 9ZXL1951D Datasheet Description The 9ZXL1951D is a second-generation, enhanced performance DB1900ZL derivative buffer. The part is a pin-compatible upgrade to the 9ZXL1951A, offering a much improved phase jitter performance. It has 8 OE# pins that can be configured via SMBus to control up to 16 of the device's 19 outputs, and is packaged in a 6 x 6 mm QFN package for maximum space savings. 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 Recommended Applications ▪ Servers, Storage, Networking, SSDs Features ▪ LP-HCSL outputs with 85Ω Zout; eliminates 76 termination resistors, saves 130mm2 area ▪ 8 OE# pins configurable to control up to 16 outputs; easy power management ▪ 9 selectable SMBus addresses; multiple devices can share same SMBus segment ▪ Selectabl...
