ICS8343I-01
LOW SKEW, 1-TO-16
LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
ICS
The ICS8343I-01 is a low skew, 1-to-16
LVCMOS/LVTTL Fanout Buffer and a member of
HiPerClockS™ 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-
www.DataSheetto4-Up.acormt skew characteristics make the ICS8343I-01 ideal for
those clock distribution applications demanding well defined
performance and repeatability.
FEATURES
• 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
