Low Skew, 1-to-2 LVCMOS / LVTTL

Fanout Buffer W/ Complementary Output 8302I-01

Datasheet

DESCRIPTION

The 8302I-01 is a low skew, 1-to-2 LVCMOS/LVTTL Fanout Buffer

w/Complementary Output. The 8302I-01 has a single ended clock

input. The single ended clock input accepts LVCMOS or LVTTL input

levels. The 8302I-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

8302I-01 ideal for clock distribution applications demanding well deﬁ

ned 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 lead-free compliant package
