ICS5342 GENDAC
16-Bit Integrated Clock-LUT-DAC
General Description
The ICS5342 GENDAC is a combination of dual programmable clock generators, a 256 x 18-bit RAM, and a triple 8-bit video DAC. The GENDAC supports 8-bit pseudo color applications, as well as 15-bit, 16-bit, and 24-bit True Color bypass for high speed, direct access to the DACs. The RAM makes it possible to display 256 colors selected from a possible 262,144 colors. The dual clock generators use Phase Locked Loop (PLL) technology to provide programmable frequencies for use in the graphics subsystem. The video clock contains 8 frequencies, all of which are programmable by the user. The memory clock has two programmable frequency locations.
