Micrel, Inc. 3.3V ECL/PECL 2:8 DIFFERENTIAL FANOUT BUFFER SY100E310L SY100E310L s Guaranteed AC performance over temperature and voltage • > 800MHz fMAX typical • < 50ps within-device skew s Low voltage operation • LVPECL +3.3V ±10% • LVECL ±10% s Internal pull-down resistors s Guaranteed over industrial temperature range: to +85°C s Pin-for-pin, plug-in replacement for MC100LVE310 s Available in 28-pin PLCC package The SY100E310L is a 3.3V, precision 2:8 ECL/PECL fanout buffer optimized for precision low-skew clock distribution. The SY100E310L features fully differential clock paths to minimize both device and system skew resulting in skew performance of < 50ps. In addition, the device includes a 2:1 multiplexer input for redundant switchover applications. The SY100E310L is optimized for low voltage +3.3V LVPECL or LVECL applications.
