Features
The TW8813 incorporates many of the features required to
create multi-purpose in-car LCD display system in a single
package. It integrates a high quality 3D comb
NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs,
dual scalers for PIP and dual-PIP support, LVDS, bit-mapped
OSD, TCON, triple DACs and images enhancement functions
which include Black and White Stretch, favorite color
enhancement and edge enhancement. To further facilitate the
move to wide screen displays, it also supports panoramic
scaling. On the input side, it supports a rich combination of
CVBS, S-video, YPbPr, analog RGB as well as digital
YCbCr/RGB inputs. On the output side, it supports both digital
and analog panel type with its LVDS and analog RGB output.
TW8813 also has a PIP (Picture in Picture) function that can
display two sources display simultaneously on single display
window. It also has built-in bit-mapped OSD with acceleration
as well as 16-bit external OSD support.
Analog RGB Inputs
• Triple high speed 10-bit ADCs with clamping and
programmable gain amplifier.
• Up to three independent RGB / YPbPr channels with
corresponding SOG
• Built-in line locked PLL with sync separator
• Allows high resolution components inputs like DTV 480p,
720p, 1080i
• 24bit Digital RGB and 8/16/24-bit YCbCr Inputs
• Allows connection with alternative Video and PC Graphics
inputs.
• Support both 656 and 601 video formats
• Allows connection to external HDMI receiver
• Support additional digital 18-bit input when main digital
input is 18-bit mode
