controller before. They are already for many years a Color DAC
I think that this G335 is something similar to what Music
Semiconductor provides = a color DAC + frequency synthesizer (PLL)
for generating the pixel clock (to the shift register) and
probably the memory clock.
Cirrus (and Sierra) decided to skip this type of product and go straight
to a fully integrated solution, that also includes the SVGA
controller and the accelerator.
It would be nice to have a look at the SGS data sheet. Rogier if you can
get me a copy, it would be greatly appriciated
