ICS83940-02
LOW SKEW, 1-TO-18
DIFFERENTIAL-TO-LVCMOS/LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83940-02 is a low skew, 1-to-18 Fanout
Buffer and a member of the HiPerClockS
family of High Performance Clock Solutions from
ICS. The 83940-02 has two selectable clock in-
puts. The CLK0, nCLK0 pair can accept most
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 50
Ω
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.
