ICS8302I-01 Integrated Circuit Systems, Inc. LOW SKEW, 1-TO-2 LVCMOS / LVTTL FANOUT BUFFER W/ COMPLEMENTARY OUTPUT GENERAL DESCRIPTION FEATURES T h e I C S 8 3 0 2I-01 i s a l ow s kew, 1 - t o - 2 LVCMOS/LVTTL Fanout Buffer w/ComplemenHiPerClockS™ tary Output a n d a m e m b e r o f t h e HiPerClock S ™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. T h e 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. • Complementary LVCMOS / LVTTL output ICS • 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 BLOCK DIAGRAM PIN ASSIGNMENT VDDO VDD CLK GND Q CLK 1 2 3 4 8 7 6 5 Q GND VDDO nQ ICS8302I-01 nQ 8-Lead SOIC 3.8mm x 4.8mm, x 1.47mm package body M Package Top View 8302AMI-01 www.icst.com/products/hiperclocks.html 1 REV.
