MTV121
Super On-Screen-Display for LCD Monitor
GENERAL DESCRIPTION
MTV121 is designed for LCD monitor applications
to display the built-in characters or fonts onto an LCD
monitor screen. The display operation is by transfer-
ring data and control information from micro control-
ler to RAM through a serial data interface. It can
execute full screen display automatically and spe-
cific functions such as character background color,
bordering, shadowing, blinking, double height and
width, font by font color control, 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 and
shadowing on window.
MTV121 provide 256 standard and 16 multi-color
fonts for more efficacious applications. The full OSD
menu is formed of 15 rows x 30 columns which can
be positioned on anywhere of the monitor screen by
changing vertical delay or horizontal delay.
Moreover, MTV121 also provide 8 PWM DAC
channels with 8 bits resolution and a PWM clock out-
put for external digital to analog control.
