GENERAL DESCRIPTION
FEATURES
The ICS8343 is a low skew, 1-to-16 Fanout • 16 LVCMOS outputs
,&6
Buffer and a member of the HiPerClockS
• Output frequency up to 200MHz
HiPerClockS™ family of High Performance Clock Solutions
from ICS. The ICS8343 is at 3.3V, 2.5V and
• 250ps output skew
• 700ps part to part
mixed 3.3V input and 2.5V supply modes over
the commercial temperature range. Guaranteed output and
part-to-part skew characteristics make the ICS8343 ideal for
those clock distribution applications demanding well defined
performance and repeatability.
• CMOS compatible clock input at 5V, LVTTLand LVCMOS
compatible at 3.3V and 2.5V
• LVTTLoutput enable inputs
• Dual output enable inputs facilitates 1-to-16 or 1-to-8 input to
output modes
• 3.3V, 2.5V or mixed 3.3V, 2.5V from 0°C to 70°C ambient
operating temperature
• 32 lead low-profile QFP(LQFP), 7mm x 7mm x 1.4mm
package body, 0.8mm package lead pitch
