Description
The 9ZXL1530D is a second-generation enhanced-performance DB1900ZL-derivative differential buffer. The part is a pin-compatible upgrade to the 9ZXL1530B while offering a much-improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
