This single serial data stream simplifies the transmission of PCB traces and cables over the 24-bit bus by eliminating the problem of bias between parallel data and clock paths. It saves system costs and narrows the data path, which reduces the size and pins of PCB layers, cable widths, and connectors. DS90C241/DS90C124 uses LVDS high-speed I/O signals LVDS provides a low-power and low-noise environment for reliable data transmission over serial transmission paths. By optimizing the serializer output edge rate, the operating frequency range EMI is further reduced.   In addition, the device has a pre-emphasis on signals that increase the distance to where the lossy cable is no longer in use. Internal DC balanced encoding/decoding is used to support AC-coupled interconnects.
