3.0 FUNCTIONAL DESCRIPTIONS
3.1 SERIAL DATA INTERFACE
The serial data interface receives data transmitted from an external controller. And there are 2 types of bus
can be accessed through the serial data interface, one is SPI bus and other is I
3.1.1 SPI bus
While SSB pin is pulled to "high" or "low" level, the SPI bus operation is selected. And a valid transmission
should be starting from pulling SSB to "low" level, enabling MTV038 to receiving mode, and retain "low" level
until the last cycle for a complete data packet transfer. The protocol is shown in Figure 1.

Serial clock input. The clock-input pin is used to synchronize
the data transfer. It has an internal pull-up resistor.
Red video input. It is used for auto sizing measurement and
this signal is came from video pre-amp red output.
Green video input. It is used for auto sizing measurement and
this signal is came from video pre-amp green output.
Blue video input. It is used for auto sizing measurement and
this signal is came from video pre-amp blue output.
No connection.
Digital power supply. Positive 5 V DC supply for internal digi-
tal circuitry and a 0.1uF decoupling capacitor should be con-
nected across to VDD and VSS.
Vertical input. This pin is used to input the vertical synchroniz-
ing signal. It is leading triggered and has an internal pull-up
resistor.
Intensity color output. 16-color selection is achievable by
combining this intensity pin with R/G/B output pins.
Fast Blanking output. It is used to cut off external R, G, B sig-
nals of VGA while this chip is displaying characters or win-
dows.
Blue color output. It is a blue color video signal output.
Green color output. It is a green color video signal output.
Red color output. It is a red color video signal output.
Digital ground. This ground pin is used to internal digital cir-
cuitry.
