description

The ‘LVDS388 and ‘LVDT388 (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.
