General Description
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.
