DATASHEET
LCD Video Processor with Built-In Decoder, MCU, OSD,
TCON and Analog RGB Input Support
TW8835
The TW8835 incorporates many of the features required to
create multipurpose in-car LCD display system in a single
package. It integrates a high quality 2D comb
NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs,
high quality scaler, versatile OSD and high performance MCU.
Its image video processing capability includes arbitrary
scaling, panoramic scaling, image mirroring, image
adjustment and enhancement, black and white stretch, etc. On
the input side, it supports a rich combination of CVBS, S-video,
component video, analog RGB as well as digital YCbCr/RGB
inputs. On the output side, it supports a variety of digital panel
types with its built-in timing controller. The integration of
additional touch screen controller, LED driver controller, PWM
and MCU makes this a versatile solution for many portable
applications.
Applications
• In-car display
• Portable DVD and DVR players
• Portable media players
Features
Analog Video Decoder
• NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination),
PAL (60), SECAM with automatic format detection
• Three 10-bit ADCs and analog clamping circuit.
• Fully programmable static gain or automatic gain control for
the Y or CVBS channel
• Programmable white peak control for the Y or CVBS channel
• Software selectable analog inputs allow composite, S-video,
analog YPbPr or RGB
• High quality adaptive 2D comb filter for both NTSC and PAL
inputs
• PAL delay line for color phase error correction
• Image enhancement with 2D dynamic peaking and CTI
• Digital subcarrier PLL for accurate color decoding
• Digital horizontal PLL and advanced synchronization
processing for VCR playback and weak signal performance
• Programmable hue, brightness, saturation, contrast,
sharpness
• High quality horizontal and vertical filtered down scaling
with arbitrary scale down ratio
