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. In bypass mode, the 9ZX21901D can provide outputs up to 400MHz.
