Description

The 9ZXL1231E is a second-generation, enhanced-performance DB1200ZL differential buffer. The part is a pin-compatible upgrade to the 9ZXL1231A while offering much-improved phase jitter performance and increased system security features. A fixed external feedback maintains low drift for critical QPI/UPI applications.
