DESCRIPTIONS
The PLL103-04 is a 1-to-4 Clock Distribution Buffer,
reproducing the reference input frequency (FIN) at 4
different outputs. It is designed to minimize skew
between outputs and provides TTL and CMOS
compatible output levels. An output enable selector is
available to tri-state all outputs.
