LC82103 Datasheet, PDF (5/5 Pages) Sanyo Semicon Device – Image-Processing LSI for Facsimile, Copier, and OCR Applications

Application Example
LC82103
1. C1 is a 0.01 µF laminated ceramic capacitor
2. The video signal from the image sensor must be set up with a polarity that has white data being the highest potential
and black data being the lowest. If the peak level of the video signal from the image sensor does not reach a
maximum value of 4.2 V, a level conversion circuit should be inserted to allow the full dynamic range of the A/D
converter to be taken advantage of.
3. Although AGND and DGND are fully isolated within the LSI, AV_DD and DV_DD are connected through the LSI
substrate. Accordingly, AV_DD and DV_DD must be set up so that there is no potential difference between them. Also,
the time lag between these signals must be under 3 ms when power is first applied or when power is turned off.
