w w w The Bt457 and Bt458 are pin- and software-compatible RAMDACs designed specifically for high-performance, high-resolution color graphics. The architecture enables a display of 1280 x 1024 bit-mapped color graphics (up to 8 bits per pixel plus up to 2 bits of overlay information). This minimizes the use of costly ECL interfacing, because most of the high-speed (pixel clock) logic is contained on-chip. The multiple pixel ports and internal multiplexing enable TTL-compatible interface (up to 3.
