9ZXL1930D - 19-Output DB1900ZL PCIe Zero-Delay/Fanout Clock Buffer
Pin-to-pin with improved performance
Pin-to-pin with improved performance
The 9ZXL1930 is a low-power version of the 9ZX21901. It has 19 low-power HCSL-compatible outputs and meets all the performance requirements of the Intel DB1900Z specification, while reducing power consumption more than 50% from the original IDT9ZX21901. It is suitable for PCI-Express Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift for demanding QPI/UPI applications.
