General Description
The ICS5342 GENDAC is a combination of dual programma-
ble clock generators, a 256 x 18-bit RAM, and a triple 8-bit
video DAC. The GENDAC supports 8-bit pseudo color appli-
cations, 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 program-
mable frequencies for use in the graphics subsystem. The vid-
eo clock contains 8 frequencies, all of which are
programmable by the user. The memory clock has two pro-
grammable frequency locations.
The three 8-bit DACs on the ICS5342 are capable of driving
singly or doubly-terminated 75
loads to nominal 0 - 0.7
volts at pixel rates up to 135 MHz. Differential and integral
linearity errors are less than 1 LSB over full temperature and
VDD ranges. Monotonicity is guaranteed by design. On-chip
pixel mask register allows displayed colors to be changed in
a single write cycle rather than by modifying the color palette.
ICS is the world leader in all aspects of frequency (clock) gen-
eration for graphics, using patented techniques to produce
low jitter video timing.
