Low Voltage Differential Signalingeesn offset of 1.25V. Integrated circuits based onVDS technology distribute signals with low-jitter, while creating little noise.peak-oltage level is reduced as well. The lower voltage level reduces the poweronsumption and the generated noise from data transmission. Another benefit of theThe method used to transfer the video information from the Main circuit board to thLCD drive circuit is called Low Voltage Differential Signaling (LVDS). LVDS devicestypically consume less power than other signaling systems such as TTL. LVDS devicuse a constant current driver. Therefore, power consumption is independent offrequency. The LVDS interface voltage is much less than TTL, approximately 2V. Thevoltage swing is typically 350mV with aLIn this application, three 8-bit streams of data are converted from parallel to serial andinterleaved. The interleave process makes the data less susceptible to noise. Theto-peak vcLVDS standard is minimal concern for cable length. The data rates for LVDS are 110Mbps for a 1-meter distance, dropping to 90 Mbps over a 10-meter distance.Figure 2730
