description

The TLC34058-110M 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 eight bits per pixel resolution) with two bits of

overlay information. The TLC34058-110M 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 TLC34058-110M

generates red, green, and blue signals compatible with EIA RS-343-A and can drive 75-

Ω coaxial cables

terminated at each end without external buffering.
