The x91LVDS388 and x91LVDT388 (T?designates integrated termination) are eight 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-V supply rail. Any of the eight differential receivers will provide a valid logical output state with a ±100-mV 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. Additionally, the high-speed switching of LVDS signals always require the use of a line impedance matching resistor at the receiving end of the cable or transmission media. The LVDT product eliminates this external resistor by integrating it with the receiver.
