Oki Electric Develops Image LSIs for In-vehicle Applications
[Main Features & Specifications]
ML86V7668 (Video decoder)
A digital video decoder compatible with SECAM signal in addition to NTSC and PAL signals, with features including "adaptive two-dimension Y/C separation(*1)". It can be used for in-vehicle applications.
- Video input signal:
- NTSC/ PAL/ SECAM
- Video input port:
- S-Video x3/Composite x4
- Operating frequency:
- 27MHz/24.545454MHz
- Data output:
- Y/CbCr 16bit,Y/CbCr 8bit/RGB 18bit
- Operating temperature range:
- -40°C to 85°C
- Power voltage:
- I/O 3.3V, Core 2.5V
- Package:
- 100pinTQFP
ML86V7655 (Video encoder)
This digital video encoder can simultaneously output three signals: the standard composite video signal(*2), S-Video signal(*3), and component signal(*4). It also includes functions such as I/P converter(*5) and P/I converter(*6) that can be used in-vehicle applications. With this function, when NTSC (525i) image data is inputted, interlace D1(525i)(*7) and progressive D2 (525p) signals are outputted from the analog component.
- Video output signal:
- NTSC/PAL
- Data input:
- Y/CbCr10bit/20bit//30bit, RGB30bit
- Input method:
- Handles both interlace and progressive
- Format converter:
- Converts to I/P and P/I
- Output format:
- Simultaneously outputs component (D1/D2) or RGB, Composite, and S-Video
- Copy card output functions:
- ML86V7656 capable. (Pin-compatible with ML86V7655)
- Operating temperature:
- -40°C to 85°C
- Power voltage:
- I/O 3.3V, Core 2.5V
- Packaging:
- 100pin TQFP
The below picture displays the component (D1/D2). While all lines are displayed with high image quality D2 signal (progressive), the general-use D1 signal (interlace) displays every other line.

Left : Interlace / Right : Progressive

[Glossary]
- *1 Adaptive two-dimension Y/C separation:
- This is a Y/C separation method using the vertical and horizontal pixel data in the screen for separation.
- *2 Composite Signal:
A video signal that overlays the brightness signal and color signal into a single signal.-
- *3 S-Video Signal:
- This is a video signal that separates the brightness signal and color signal. This enables higher quality than that of the composite signal because there is no need for Y/C separation.
- *4 Component Signal:
- A video signal that is divided into three signals including the brightness signal and two color signals. It has higher quality than that of the S-Video signal used in image equipment.
- *5 I/P Convert (Convert from Interlace to Progressive):
- This is a function to convert and interlace signal into a progressive signal. Interlace is an output format for TVs and videos that displays images by dividing them into even and odd lines and displays them alternatively, while the progressive format displays both the even and odd lines simultaneously. Under NTSC, interlace displays 60 fields of 252.5 lines of even and odd lines alternately per second. Progressive displays 60 fields of 525 lines per second.
- *6 P/I Converter (Converts from progressive to interlace):
- This is a function to convert a progressive signal into an interlace signal.
- *7 Interlace D1(525i) / Progressive D2 (525p):
- D1/D2 is the name for the component signal used for high-quality images at the D port in the case of NTSC. The standard range is from D1 to D4, where D1: 525i, D2: 525p, D3: 1080i, and D4: 720p (numbers are the number of lines)
Oki's ML86V7655 and 7656 comply with D1 and D2. 525i is the NTSC interlace signal, and 525p is the NTSC progressive signal. The PAL signal (Interlace) is 625i.
