8.1.1 Typical Application

The SN55LVTA4-SEP is generally used as a building block for high-speed point-to-point data transmission where ground differences are less than 1V. The SN55LVTA4-SEP can inter-operate with RS-422, PECL, and IEEE-P1596. Drivers/receivers approach ECL speeds without the power and dual supply requirements.

SN55LVTA4-SEP Typical Transmission Distance Versus Signaling Rate
A. This parameter is the percentage of distortion of the unit interval (UI) with a pseudo-random data pattern.
Figure 8-1 Typical Transmission Distance Versus Signaling Rate
SN55LVTA4-SEP Operation With 5V Supply
A. Place a 0.1μF Z5U ceramic, mica, or polystyrene dielectric, 0805 size, chip capacitor between VCC and the ground plane. The capacitor shall be located as close as possible to the device terminals.
B. Unused enable inputs shall be tied to VCC or GND, as appropriate.
