Advanced Video Display Processor 6
s
Outline
YGV619 is a VDP (Video Display Processor) adopting OSD display control system which is best suited to the
data broadcasting. The digital image interface of this device for connection with MPEG decoder has been
improved. The use of this device allows screen composition that is suited to mobile information terminals, car
navigation system, etc. Scan timing conforming to the display standard of digital TVs can be made.
Two built-in PLL circuits allows to realize superimposition of external image signal on original image signal,
and to produce clock best suited to SDRAM that is adopted as external video memory.
