LVTTL/TTL/CMOS-to-Differential LVECL/
ECL Translators
General Description
The MAX9360/MAX9361 are low-skew, single LVTTL/
TTL/CMOS-to-differential LVECL/ECL translators
designed for high-speed signal and clock driver appli-
cations. For interfacing to LVTTL/TTL/CMOS input sig-
nals, these devices operate over a 3.0V to 5.5V supply
range, allowing high-performance clock or data distrib-
ution. For interfacing to differential LVECL/ECL output
signals, these devices operate from a -2.375V to -5.5V
supply.
The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL
translator that operates at a typical speed of 3GHz. The
MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator
that operates at a typical speed of 1.3GHz. Both
devices can be used to drive either LVECL devices or
standard ECL devices with a negative supply range of
-2.375V to -5.5V.
The devices default to high if the input is disconnected,
and feature ultra-low propagation delay: 440ps for the
MAX9360, 810ps for the MAX9361.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
