GENERAL DESCRIPTION

The ICS8343 is a low skew, 1-to-16 Fanout

,&6

HiPerClockS™

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.

Buffer and a member of the 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

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

ABSOLUTE MAXIMUM RATINGS

Supply Voltage 7V
Inputs -0.5V to VDD+0.5 V
Outputs -0.5V to VDD+0.5V
Ambient Operating Temperature 0°C to 70°C
Storage Temperature -65°C to 150°C

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These ratings are stress specifi­cations only and functional operation of the device at these or any conditions beyond those listed in the DC Electrical Characteristics or AC Electrical
Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.
