9ZXL1950 Description
The 9ZXL1950 is a DB1900Z derivative buffer utilizing Low-Power HCSL (LP-HCSL) outputs to increase edge rates on long traces, reduce board space, and reduce power consumption more than 50% from the original 9ZX21901.It is pin-patible to the 9ZXL1930 and fully integrates the output terminations. It is suitable for PCI-Express Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift...
