HIGH-SPEED DIFFERENTIAL LINE DRIVERS

The SN75LVDS32 and SN75LVDS9637 are differential line receivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5-V differential standard levels (such as EIA/TIA-422B) to reduce the power, increase the switching speeds, and allow operation with a 3.3-V supply rail. Any of the four differential receivers provides a valid logical output state with a 100 mV allow operation with a differential input voltage within the input common-mode voltage range. The input common-mode voltage range allows 1 V of ground potential difference between two LVDs nodes. The intended application of these devices and signaling technique is both point-to-point and multidrop (one driver and multiple receivers) data transmission over controlled impedance media of approximately 100 . 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 SN75LVDS32 and SN75LVDS9637 are characterized for operation from 0C to 70C. By Texas Instruments
