BT457 Overview
Key Features
- This minimizes the use of costly ECL interfacing, because most of the high-speed (pixel clock) logic is contained on-chip
- The Bt457 is a single-channel version of the Bt458 and has a 256 x 8 color lookup table with a single 8-bit video D/A converter
- It includes a PLL output to enable subpixel synchronization of multiple Bt457s
