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.
s Features

Up to four planes, which are individually composed of back drop plane (plane on which external images are inputted)
+ region, are available.
q OSD image format:
8bit/dot palette mode, and 16 bit RGB or YCbCr format can be selected.

· 18bitYCbCr444 + 2 bit AT
· 16bitYCbCr422 + 2 bit AT
· 8bitITU656 + 2 bit AT + 6 bit α blending coefficient
q Max. OSD resolution: 960 dots × 1080 lines
(However, max. resolution of overlaid external image is 1920 ×1080 lines)
q Applicable digital TV image format:
· 525i
· 525p
· 1125i
q Video capture function:
· Draws external image input on the frame memory in real time.

l RAS (O)
Outputs row address strobe signal for SDRAM.
When two 16 bit SDRAMs are used, connect this pin to both SDRAMs.
l CAS (O)
Outputs column address strobe signal for SDRAM.
When two 16 bit SDRAMs are used, connect this pin to both SDRAMs.
l WE (O)
Outputs write strobe signal for SDRAM.
When two SDRAMs are used, connect this pin to both SDRAMs.
l DQM3-0 (O)
Outputs data mask signal for SDRAM. DQM3, DQM2, DQM1 and DQM0 are mask control signals for SDQ31-24,
SDQ23-16, SDQ15-8 and SDQ7-0 respectively. When masking the data, corresponding DQM pin outputs high level
signal.
When one 16 bit SDRAM is used, DQM3-2 pins are not used, thus they are to be kept open.
l SDCLK (I/O)
Outputs CLK for SDRAM. SDCLK inputs the clock once outputted from this pin to use it as fetch clock to obtain
setup time at SDQ input.
< Display monitor interface >
l R, G, B (O: analog output)
Outputs linear RGB signal. Termination resistor of 37.5is connected to this pin to make the resolution of output
voltage amplitude 8 bits. Monitor with impedance of 75can be driven directly through this interface as shown below.
R(G,B)
RL=75
RL=75
l REXT (I: analog input)
A resistor is connected between this pin and GND(AVSS4) for adjusting the amplitude of signal outputted from DAC
for RGB. The standard amplitude of signal outputted from DAC is 0.7 V (rREXT=470 ). The amplitude of the output
can be adjusted finely within around ±100by using the following formula.
Vp_p = 470 × 0.7 / rREXT
l CSYNC (O)
Outputs composite sync signal for external monitor. In interlaced scanning mode, equalizing pulses are added to this
signal. This pin can output VSYNC by using internal register setting.
l HSYNC (O)
Outputs horizontal sync signal for external monitor.
l BLANK (O)
Outputs a signal that indicates effective display period when LCD panel is connected to the device.
l AT1-0 (O)
AT1-0 bits of display data are outputted from these pins.
l FSC (O)
Outputs subcarrier clock for video encoder. The subcarrier clock is created by dividing the clock inputted to DCKIN
pin by 1, 2, 4, or 8, which is determined by register setting. For example, inputting 14.318 MHz to DCKIN pin and
dividing it by “4” give subcarrier clock of 3.58 MHz.
