well as specific 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 spac-ing, horizontal display resolution, full-screen erasing, fade-in.fade-out effect,
windowing effect and shad-owing on window.
• MTV021 provides 256 standard and 16 multi-color characters and graphic fonts for more efficacious
applications. The full OSD menu is formed by 15 rows x30 columns, which can be positioned any-
where on the monitor screen by changing vertical or horizontal delay
• Moreover, MTV021 also provides 8 PWM DAC channels with 8-bit resolution and a PWM clock out
put for external digital-to-analog control.
