10. TOH2600DGI4KRA(26MHz)
This system uses the 26MHz TCXO, TOH2600DGI4KRA, SEM. AFC control signal from OM6359 controls frequency
from 26MHz x-tal. The clock output frequency of UAA3536 is 13MHz. This clock is connected to OM6359, YMU762C.
11. Camera DSP(MV317S)
Tiger is an Integrated circuit for mobile phone camera. This structure will allow effectiveness for large
data management and significantly reduces main processor will get burden.
In hence, Tiger will allow the user to be able to display to LCD direct without burdening the main
processor. It also allows to have various kinds of display size on the LCD and snapshot for Jpeg. Digital
effect will also be executed on real time base resulting Tiger as being a video co-processor in the
mobile platform. Also,an i80 type processor' s 16bit parallel interface of Tiger makes it available for the CPU to
interchange the data with Tiger. As the additional 8Mbit is usable except 2Mbit buffer embedded in Tiger, the diverse UI
data processing which is not a burden to the CPU is available. JPEG encoder and decoder are baseline
ISO/IEC 10918-1 JPEG compliance (DCT-based). JPEG decoder supports YUV444, YUV422, YUV420 and
YUV411 format standard JPEG image.
