MTV021
Enhanced Super On-Screen Display
GENERAL DESCRIPTION
MTV021 is designed for 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 color, bor-
dering, 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 x 30 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.
