MTV038N Datasheet – Display Controller for CRT/LCD Monitor
On-screen-display controller for CRT/LCD monitor
MTV038N overview
The MTV038N is an On-screen-display controller for CRT/LCD monitor made by Myson Century Inc, supplied in these packages: DIP, SOP 16 Pin Type. The absolute maximum ratings table on this page lists the 4 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the MTV038N pinout and maximum ratings, with the full datasheet PDF to preview below or download.
MTV038 is designed for CRT/LCD monitor applications to display built-in characters or fonts onto monitor screens. The display operation occurs by transferring data and control information from the micro-controller to RAM through a serial data interface. It can execute full-screen display automatically, as well as specific functions such as character background, bordering, shadowing, blinking, double height and width, font by font color control, character but- ton boxes, frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-screen erasing, fade-in/fade-out effect, windowing effect, shadowing on window and full-screen self- test pattern generator.
MTV038 provides 544 fonts including 512 standard fonts and 32 multi-color fonts and 2 font sizes, 12x16 or 12x18 for more efficacious applications. The full OSD menu is formed by 15 rows x 30 columns, which can be positioned anywhere on the monitor screen by changing vertical or horizontal delay.
The auto sizing video measurement module measure the timing relationship among HFLB, VFLB, and R, G, BIN with 12-bit resolution at the speed related to the OSD pixel clock. And the R, G, BIN input level can be programming by software. MCU can get the measurement data, active video, front Porth and back Porth, through I2C bus read/ write operation to keep the appropriate display size and center.

MTV038N pinout
| Name | Description |
|---|---|
| VSSA | Analog ground. This ground pin is used to internal analog circuitry. |
| VCO/XIN | 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. MTV038 can be driven by an external pixel clock source for all the logics inside. The f |
| RP/NC | Bias Resistor (bit LCD= 0). The bias resistor is used to regu- late the appropriate bias current for internal oscillator to reso- nate at specific dot frequency. No connection (bit LCD= 1). |
| VDDA | Analog power supply. Positive 5 V DC supply for internal analog circuitry. And a 0.1uF decoupling capacitor should be connected across to VDDA and VSSA. |
| HFLB | Horizontal input. This pin is used to input the horizontal syn- chronizing signal. It is a leading edge triggered and has an internal pull-up resistor. |
| SSB | 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. |
| SDA | Serial data input. The external data transfer through this pin to internal display registers and control registers. It has an inter- nal pull-up resistor. |
