standard differential input levels. The single ended clock in-
put accepts LVCMOS or LVTTL input levels.The low imped-
ance LVCMOS/LVTTL outputs are designed to drive 50Ω
series or parallel terminated transmission lines. The effective
fanout can be increased from 18 to 36 by utilizing the ability
of the outputs to drive two series terminated lines.
The ICS83940-02 is characterized at full 3.3V, full 2.5V and
mixed 3.3V input and 2.5V output operating supply modes.
Guaranteed output and part-to-part skew characteristics
make the ICS83940 ideal for those clock distribution applica-
tions demanding well defined performance and repeatability.
