843256BGILF General Description

The 843256I 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 843256I make it an ideal clock for these demanding applications.

Key Features

Eight 3.3V LVPECL output pairs
Output frequency range: 62.5MHz to 625MHz
RMS phase jitter at 156.25MHz using a 25MHz crystal: 0.85ps (typical) @ 2.5V
