DATASHEET
General Description
Features/Benefits
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-compatible 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 for demanding QPI/UPI applications.
• LP-HCSL outputs; up to 90% IO power reduction, better
