TKD8001

The TKD8001 is the combination of clock synthesizer and display DAC. The device can be used with VGA, Super VGA, GUI, 8514/A, etc color graphic systems. The chip includes 8-bit display DACs, a 256*24 color look-up table, and two clock synthesizers. The display DACs can generate RS-343A compatible red, green, and blue signals into a doubly terminated 75 load without external buffering.

There are some features of TKD8001 as follows: (1)combines a triple display DAC, clock look-up table (256*24), and dual frequency synthesizer; (2)supports 4/8/15/16/24-bit per pixel modes; (3)supports gamma corrected or CLUT bypass versions  of the 15/16/24-bit per pixel modes; (4)anti-sparkle circuitry; (5)VGA, super VGA, VESA, and 8514/A compatible; (6)supports XGA, TARGA+, and HiCOLOR formats; (7)16 selectable video clock frequencies (VCLK) up to 80 MHz; (8)16 software selectable or eight hardware selectable memory clock frequencies (MCLK) up to 90 MHz; (9)standard MPU interface; (10)RS-343A and RS-170 compatible outputs; (11)power-on reset; (12)power-down mode for extended battery life; (13)0.8m low power CMOS technology; (14)52-pin, PLCC package; (15)complete Super VGA subsystem requires only 5 active components: graphics controller, BIOS, memory (2 each), and TKD8001.
