ICS8343
LOW SKEW 1-TO-16
FANOUT BUFFER
GENERAL DESCRIPTION
The ICS8343 is a low skew, 1-to-16 Fanout
,&6 Buffer and a member of the HiPerClockS
HiPerClockS™ family of High Performance Clock Solutions
from ICS. The ICS8343 is at 3.3V, 2.5V and
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
www.DataSheept4eUrf.ocormance and repeatability.
FE ATURES
• 16 LVCMOS outputs
• Output frequency up to 200MHz
• 250ps output skew
• 700ps part to part
• CMOS compatible clock input at 5V, LVTTL and LVCMOS
compatible at 3.3V and 2.5V
• LVTTL output 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
