WebMar 10, 2024 · However, LVDS provides additional desirable features for high-speed transmission. First, the voltage compliance is doubled, because the signal is no longer limited to the single-ended output: for instance, if the maximum amplitude of each line is 1.65 V, then the differential amplitude is 3.3V (1.65V – (-1.65V)). WebThe amplitude and frequency are adjusted via the signal generator. Figure 2. AD8138 drives CAN transceiver. Operating from a single 5-V supply, the circuit is configured as a unity-gain single-ended-to-differential amplifier with common mode set at midsupply. R1, R2, and R3 form the dc biasing circuit that scales the output signals to CAN levels.
