P Digital power supply.
DD
G Digital Ground
I 10-Bit Progressive scan/ HDTV input port for CrCb color data in 4:2:2 input mode.
When this input pin is brought low, the ADV7300 interfaces over the SPI port and uses this
I input as part of the 4 wire SPI interface. When this input pin is tied high [VDD_IO], the ADV7300
interfaces over the I2C port.
I/O Multifunctional pin.
I/O Multifunctional pin.
I Multifunctional input.
Video Horizontal Sync Control Signal for HD sync in simultaneous SD/HD mode
I
and HD only mode.
Video Vertical Sync Control Signal for HD sync in simultaneous SD/HD mode
I
and HD only mode.
I Video Blanking Control Signal for HD sync in simultaneous SD/HD mode and HD only mode.
I Multifunctional input.
I Pixel Clock Input for HD only or SD only modes.
This input resets the on-chip timing generator and sets the ADV7300 into Default Register
I
setting. Reset is an active low signal.
I External Loop filter for the internal PLL.
A1520 Ohms resistor must be connected from this pin to AGND and is used to control the
I
amplitudes of the DAC outputs.
O Compensation Pin for DACs.
In SD only mode: Chroma/RED/V analog output.
