9ZX21901D Datasheet (IDT) - 19-Output DB1900Z

9ZX21901D, 19-Output DB1900Z

The 9ZX21901D is a second generation DB1900Z differential buffer for Intel Purley and newer platforms.

The part is backwards compatible to the 9ZX21901C while offering much improved phase jitter performance.

A fixed external feedback maintains low drift for critical QPI/UPI applications.
