FEATURES
4 outputs identical to FIN.
Low skew (< 250 ps between outputs).
Input / Output frequency range 0 160 MHz
25mA drive capability at TTL levels.
70mA drive capability at CMOS levels.
Output enable mode available to tri-state all
outputs.

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.
PIN CONFIGURATION
Note: ^: Internal pull-up (30k
