The DS90C241 and DS90C124 chipset translates a 24-bit parallel bus into a fully transparent data and control LVDS serial stream with embedded clock information. This single serial stream simplifies transferring a 24-bit bus over PCB traces or over cable by eliminating the skew problems between parallel data and clock paths. It saves system cost by narrowing data paths, which in turn reduces PCB layers, cable width, and connector size and pins.

The DS90C241 and DS90C124 incorporate LVDS signaling on the high-speed I/O. LVDS provides a low-power and low-noise environment for reliably transferring data over a serial transmission path. By optimizing the serializer output edge rate for the operating frequency range, EMI is further reduced.

In addition, the device features pre-emphasis to boost signals over longer distances using lossy cables. Internal DC balanced encoding and decoding supports AC-coupled interconnects.Read more
