This signaling technique lowers the output voltage levels of 5-V differential VCC 1 1A 2 2A 3 GND 4 8 1Y 7 1Z 6 2Y 5 2Z 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 magnitude of 247 m V into a 100-Ω load when enabled. The intended application of these devices and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100 Ω. 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 SN75LVDS31 and SN75LVDS9638 are characterized for operation from 0°C to 70°C.
