Description

The SN55LVTA4-SEP is a differential line driver that implements the electrical characteristics of low-voltage differential signaling (LVDS) with a 3.3V supply. This driver delivers a minimum differential output voltage magnitude of 247mV into a 100Ω load when enabled.

The intended application of this device and signaling technique is both point-to-point and multi-drop (one driver and multiple receivers) data transmission over controlled impedance media of approximately 100Ω. The transmission media can 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 SN55LVTA4-SEP is characterized for operation from –55°C to 125°C.
