Description

The 9ZXL1950D is a second-generation, enhanced-performance DB1900Z-derivative differential buffer. The part is a pin-compatible upgrade to the 9ZXL1950B while offering a much-improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
