Descriptions
- 1 1 1 Ground. This ground pin is used to internal circuitry.
I 2 2 2 Pixel clock input. This is a clock input pin. MTV121 is driven by an exter-
nal pixel clock source for all the logics inside. The frequency of XIN must
be the integral time of pin HFLB.
I 3 3 3 No connection.
- 4 4 4 Power supply. Positive 5 V DC supply for internal circuitry. And a 0.1uF
decoupling capacitor should be connected across to VDD and VSS.
I 5 5 5 Horizontal input. This pin is used to input the horizontal synchronizing
signal. It is a leading edge triggered and has an internal pull-up resistor.
I 6 6 6 Serial interface enable. It is used to enable the serial data and is also
used to select the operation of I2C or SPI bus. If this pin is left floating, I2C
bus is enabled, otherwise the SPI bus is enabled.
I 7 7 7 Serial data input. The external data transfer through this pin to internal
display registers and control registers. It has an internal pull-up resistor.
I 8 8 8 Serial clock input. The clock-input pin is used to synchronize the data
transfer. It has an internal pull-up resistor.
O - 9 9 Open-Drain PWM D/A converter 0. The output pulse width is program-
mable by the register of Row 15, Column 23.
O - 10 10 Open-Drain PWM D/A converter 1. The output pulse width is program-
mable by the register of Row 15, Column 24.

- 12 Open-Drain PWM D/A converter 3. The output pulse width is program-
mable by the register of Row 15, Column 26.
