2 / 19 page MYSON TECHNOLOGY MTV048 (Rev 0.9) Rev 0.9 - 2 - 2001/03/15 1.0 PIN CONNECTION 2.0 PIN DESCRIPTIONS Name I/O Pin NO. Descriptions VSS - 1 Analog ground. This ground pin is used for internal analog circuitry. VCO / XIN I/O 2 Voltage control oscillator (bit LCD = 0). This pin is used to control the internal oscillator frequency by DC voltage input from external low pass filter. Pixel clock input (bit LCD = 1). This is a clock input pin. MTV048 can be driven by an external pixel clock source for all the logic inside. The frequency of XIN must be the integral time of pin HFLB. RP / NC I/O 3 Bias Resistor (bit LCD = 0). The bias resistor is used to regulate the appropriate bias current for internal oscillator to resonate at specific dot frequency. No connection (bit LCD = 1). VDDA - 4 Analog power supply. Positive 5V / 3.3V DC supply for internal analog circuitry. And a 0.1uF decoupling capacitor should be connected across to VDDA and VSSA. HFLB I 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. SSB I 6 Serial interface enable. It is used to enable the serial data and is also used to select the operation of I 2C or SPI bus. If this pin is left floating, I 2C bus would be enabled. Otherwise the SPI bus is enabled. SDA I 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. SCK I 8 Serial clock input. The clock-input pin is used to synchronize the data transfer. It has an internal pull-up resistor. VDD - 9 Digital power supply. Positive 5V / 3.3V DC supply for internal digital circuitry and a 0.1uF decoupling capacitor should be connected across to VDD and VSS. VFLB I 10 Vertical input. This pin is used to input the vertical synchronizing signal. It is leading triggered and has an internal pull-up resistor. VSSA VCO/XIN VDDA HFLB SSB SDA SCK RP/NC VDD VSS ROUT GOUT FBKG V33CAP BOUT VFLB 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 |
