description

The TLC34058 color-palette integrated circuit is specifically developed for high-resolution color graphics in such

applications as CAE/CAD/CAM, image processing, and video reconstruction.

The architecture provides for the display of 1280

× 1024 bit-mapped color graphics (up to 8 bits per pixel

resolution) with 2 bits of overlay information. The TLC34058 has a 256-word

× 24-bit RAM used as a lookup

table with three 8-bit video D/A converters.

On-chip features such as high-speed pixel clock logic minimize costly ECL interface. Multiple pixel ports and

internal multiplexing provide TTL-compatible interface (up to 32 MHz) to the frame buffer while maintaining

sophisticated color graphic data rates (up to 135 MHz). Programmable blink rates, bit plane masking and

blinking, color overlay capability, and a dual-port palette RAM are other key features. The TLC34058 generates

red, green, and blue signals compatible with EIA RS-343-A and can drive, without external buffering, 75-

Ω

coaxial cables terminated at each end.
