Description
The 9ZXL1530 is a low-power version of the 9ZX21501 Intel™ DB1900Z-compatible differential buffer. It has 15 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 9ZX21501. 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.
