TW8824
LCD Video Processor with Built-in Decoder, TTL Inputs, BT.656 Output and LVDS
Panel Interface
The TW8824 is a highly integrated LCD video processor that
incorporates many of the key features required to create a
multipurpose LCD display system into a single package. This
includes a high quality 2D comb NTSC/PAL/SECAM video
decoder, which supports both single-ended and differential
CVBS signals, a digital RGB input interface, high quality scaler
and deinterlacer, a Font OSD engine and LVDS, TTL or TCON
output panel interfaces. The TW8824 can support input
resolutions up to 1080p and can drive LCD panels at
resolutions up to 1366x768. The TW8824’s video processing
capability includes arbitrary H/V scaling, panoramic scaling,
image mirroring, image adjustment and enhancement, black
and white stretch, etc. This device can support fast boot
system requirements and provides stability and reliability to
the system due to the fact that it is a hardwired solution that
can sync to the video source and display an image on the LCD
in less than 0.5 seconds from start-up. The feature set and
versatility of this device makes it an ideal solution for in-car
LCD display applications.
