Product Introduction
The 9ZXL1951DNHGI clock buffer is a second-generation, performance-enhanced DB1900ZL derivative specification buffer. This clock buffer is compatible with the 9ZXL1951A pin and features superior phase jitter performance. The 9ZXL1951DNHGI buffer is equipped with 8 OE# pins that can be configured via SMBus, capable of controlling up to 16 of the 19 output channels of the device. The 9ZXL1951DNHGI buffer adopts a 6mm x 6mm QFN package, which can save space to the greatest extent. The 9ZXL1951DNHGI buffer includes fixed external feedback, thereby maintaining low drift for critical QPI/UPI applications. The 9ZXL1951DNHGI buffer is suitable for servers, storage, networks and SSDS.
