Mixed Signal Systems
Analog LCD I/F Chipset
A/D converters and PLLs are provided for LCD monitors and projectors according to the resolution.
In XGA resolution, the A/D converters CXA3246Q (QFP) and CXA3256R (LQFP), and the PLL CXA3106Q are available.
The use of Sony's A/D converters and PLLs enables simple designing of XGA and SXGA with the same concept and gives
excellent picture quality. Moreover, the D/A converter CXA3197R, which is capable of TLL interface, is provided for
LCD projectors.
