Resources for 843256
Description
The 843256 is a Crystal-to-3.3V LVPECL clock synthesizer/fanout buffer designed for Fibre Channel and Gigabit Ethernet applications. The output frequency can be set using the frequency select pins and a 25MHz crystal for Ethernet frequencies, or a 19.44MHz crystal for SONET. The low phase noise characteristics of the 843256 make it an ideal clock for these demanding applications.
