ICS8302I-01
LOW SKEW, 1-TO-2 LVCMOS / LVTTL
FANOUT BUFFER W/ COMPLEMENTARY OUTPUT
GENERAL DESCRIPTION
The ICS8302I-01 is a low skew, 1-to-2
LVCMOS/LVTTL Fanout Buffer w/Complemen-
tary Output and a member of the
HiPerClockS™ family of High Performance
Clock Solutions from ICS. The ICS8302I-01
has a single ended clock input. The single ended clock
input accepts LVCMOS or LVTTL input levels. The
ICS8302I-01 is characterized at full 3.3V for input VDD,
and mixed 3.3V and 2.5V for output operating supply
modes (VDDO). Guaranteed output and part-to-part skew
characteristics make the ICS8302I-01 ideal for clock
distribution applications demanding well defined
performance and repeatability.
FEATURES
• Complementary LVCMOS / LVTTL output
• LVCMOS / LVTTL clock input accepts LVCMOS
or LVTTL input levels
• Maximum output frequency: 250MHz
• Output skew: 165ps (maximum)
• Part-to-part skew: 800ps (maximum)
• Small 8 lead SOIC package saves board space
• Full 3.3V or 3.3V core/2.5V output supply modes
• -40°C to 85°C ambient operating temperature
• Available in both standard and lead-free compliant
packages
