PRELIMINARY

The ICS8343I-01 is a low skew, 1-to-16

LVCMOS/LVTTL Fanout Buffer and a member of

the HiPerClockS™ family of High Performance

Clock Solutions from ICS. The ICS8343I-01

single ended clock input accepts LVCMOS or

LVTTL input levels. The ICS8343I-01 operates 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 ICS8343I-01 ideal for

those clock distribution applications demanding well defined

performance and repeatability.

• 16 LVCMOS/LVTTL outputs

• 1 LVCMOS/LVTTL clock input

• CLK can accept the following input levels: LVCMOS, LVTTL

• Maximum output frequency: 200MHz

• Dual output enable inputs facilitates 1-to-16 or 1-to-8 input

to output modes

• All inputs are 5V tolerant

• Output skew: 250ps (typical)

• Part-to-part skew: 700ps (typical)

• Full 3.3V and 2.5V or mixed 3.3V core/2.5V operating supply

• -40°C to 85°C ambient operating temperature
