Description
The 9ZX21901D is a second-generation DB1900Z differential buffer for Intel Purley and newer platforms. The part is backward compatible with the 9ZX21901C while offering much-improved phase jitter performance. Fixed external feedback maintains low drift for critical QPI/UPI applications. In bypass mode, the 9ZX21901D can provide outputs up to 400MHz.
