ICS83947
LOW SKEW, 1-TO-9
LVCMOS FANOUT BUFFER
GENERAL DESCRIPTION
The ICS83947 is a low skew, 1-to-9 LVCMOS
Fanout Buffer and a member of the HiPerClockS
family of High Performance Clock Solutions from
ICS. The low impedance LVCMOS outputs are
designed to drive 50
series or parallel termi-
nated transmission lines. The effective fanout can be increased
from 9 to 18 by utilizing the ability of the outputs to drive two
series terminated lines.
Guaranteed output and part-to-part skew characteristics
make the ICS83947 ideal for high performance, single ended
applications that also require a limited output voltage.
