APPLICATION INFORMATION

The SN55LVDS31 is generally used as a building block for high-speed point-to-point data transmission where

ground differences are less than 1 V. The SN55LVDS31 can interoperate with RS-422, PECL, and IEEE-P1596.

Drivers/receivers approach ECL speeds without the power and dual supply requirements.

A.

This parameter is the percentage of distortion of the unit interval (UI) with a pseudorandom data pattern.
