Overview

Description

The 9ZXL0831E is a second-generation enhanced performance DB800ZL differential buffer. The part is a pin-compatible upgrade to the 9ZXL0831A, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.
