ApplicationThe devices are generally used as building blocks for high-speed point-to-point data transmission where ground differences are less than 1 V. Devices can interoperate with RS-422, PECL, and IEEE-P1596. Drivers/receivers approach ECL speeds without the power and dual supply requirements.

This signaling technique lowers the output voltage levels of 5 V differential standard levels (such as TIA/EIA-422B) to reduce the power, increase the switching speeds, and allow operation with a 3.3-V supply rail. Any of the four current-mode drivers will deliver a minimum differential output voltage of SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 magnitude of 247 mV into a 100-W load when enabled.
The intended application of SN55LVDS31, SN65LVDS31,SN65LVDS3487, and SN65LVDS9638 and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100 W. The transmission media may be printed-circuit board traces,backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.
The SN65LVDS31, SN65LVDS3487, and SN65LVDS9638 are characterized for operation from 40°C to 85°C. The SN55LVDS31 is characterized for operation from 55°C to 125°C.
