Overview
... Features 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 32 MHz) to the frame buffer, while maintaining the 165 MHz video data rates required for sophisticated color graphics.
The Bt457 is a single-channel version of the Bt458 and has a 256 x 8 col...
