描述

The 9ZXL1930 is a low-power version of the 9ZX21901 19-output DB1900Z-compliant buffer. It has 19 low-power HCSL-compatible outputs and meets all the performance requirements of the Intel DB1900Z specification while reducing power consumption by more than 50% from the original 9ZX21901. It is suitable for PCI Express Gen 1/2/3 or QPI/UPI applications and uses fixed external feedback to maintain low drift for demanding QPI/UPI applications.
