DESCRIPTION
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 –3.3V LVECL applications.
