No.11060EAT05
Description
BU1523KV is an image quality adjustment IC for in-vehicle displays. It can control brightness, contrast, hue, intensity,
sharpness, etc. It is equipped with both RGB and YCbCr as input/output interfaces. It also incorporates LVDS output
capability with an embedded LVDS transmitter.
Features
1) RGB input data format
Width of data bus 24bit
Vertical/horizontal synchronizing and data enable signal
2) RGB output data format
It is the same as the entry format
3) YCbCr input data format
ITU-R BT.656-4 or synchronization signal YCbCr
Width of data bus 8bit
Vertical/horizontal synchronizing and data field signal
Date range conform ITU-R BT.601 or full range
4) YCbCr output data format
The same as the entry format
Capable of processing BT.656 input to generate and output
synchronization signal from SAV/EAV
5) RGB IF Image quality adjustment
Contrast, Brightness, Hue, Chroma and Sharpness
Independent RGB gamma correction
6) YCbCr Image quality adjustment
Contrast, Brightness, Hue, Chroma and Sharpness
7) LVDS Transmitter
Built-in LVDS transmitter
Converts RGB24 bit, vertical/horizontal synchronization signal
and data enable inputs into 4ch LVDS data streams
8) 2-line serial interface slave function
The register in BU1523KV can be set
9) Package
VQFP100
Applications
In-vehicle display etc.
