RAA278840

LCD Video Processor with Decoder, LVDS, TTL, MIPI, Improved Upscaling Engine,

and Video Integrity Diagnostic

The RAA278840 is a highly integrated LCD video

processor that incorporates many of the features

required to create a cost-effective multipurpose LCD

Features

Analog Video Decoder

system. The features include a high-quality 2D comb

NTSC/PAL/SECAM video decoder that supports

single-ended or differential composite video inputs,

two TTL digital input interfaces, two LVDS Open LDI

input interfaces, a MIPI-CSI2 input interface, and an

EEPROM/SPI interface. The outputs include a

dual-channel LVDS Open LDI panel interface and a

separate MIPI-CSI2. This device can support input

resolutions up to 1080p and can drive LCD panels up

to 1920x1080. The video processing capabilities

include arbitrary H/V scaling using a high-quality

scaler and de-interlacer engine, panoramic scaling,

image mirroring, image adjustment and enhancement

using 10-bit per color processing, black and white

stretch, a versatile OSD, and much more. Also, the

RAA278840 has a multi-feature image integrity

diagnostic capability to dynamically determine if the

input video is corrupted. The feature set and

• Supports NTSC (M, 4.43) and PAL (B, D, G, H, I, M,

N, N combination), PAL (60), SECAM with

automatic format detection

• High quality adaptive 2D comb filter for both NTSC

and PAL inputs

• 10-bit ADC and analog clamping circuit

• Fully programmable static gain or automatic gain

control for the CVBS channel

• Programmable white peak control for the CVBS

channel

• Four single-ended or two differential CVBS input

• PAL delay line for color phase error correction

• Image enhancement with 2D dynamic peaking/CTI

• Digital subcarrier PLL for accurate color decoding

• Programmable hue, brightness, saturation,

contrast, and sharpness

versatility of this device make it an ideal solution for

automotive LCD applications.

• Digital horizontal PLL and advanced

synchronization processing for superior VCR

playback and weak signal performance

Applications

• Automotive display

Digital Input Support

• Industrial/military displays

• Portable/consumer displays

• Supports two parallel digital input ports up to 32 bits

total, with many combinations such as 24 + 8, 16 +
