MAX9360/MAX9361
19-2327; Rev 2; 12/08 EVAALVUAAILTAIOBNLEKIT
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 applications. For interfacing to LVTTL/TTL/CMOS input signals, these devices operate over a 3.0V to 5.5V supply range, allowing high-performance clock or data distribution. 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.
