STV9937
General Description

General Description
The STV9937 is an Advanced On Screen Display generator for CRT monitors. It includes a specific
architecture allowing multiple menu displays, a built in 512 character ROM and the Picture
BooST
TM
system.
The patented Picture BooST
TM
feature allows images to be boosted either within a window, a
screen area or even over the entire screen.
Using traditional architecture (OSD + Preamp STV9212) and without any additional devices on the
CRT board, Picture BooST
TM
boosts the brightness and sharpness of the video on CRT displays
giving a TV like effect.
The STV9937 can drive Picture BooST
TM
either through the VGA cable (using RGB or DDC),
through the USB channel via the MCU or through the OSD menu (the registers can be accessed by
the MCU via I2C).
The STV9937 embeds the RGB data decoder, the Picture BooST
TM
Control Registers and the
Picture BooST
TM
signal generator.
Along with the Picture BooST
TM
and traditional OSD features, the STV9937 allows a simultaneous
display of up to four menus anywhere on the screen. Each of the four independent windows, all
displaying characters, can be overlapped and display priorities are automatically controlled.
●
Window sizes and positions are independently programmable as well as scrolling menu effects.
●
Programming of the general OSD and of the 4 windows is controlled by an I2C bus in Read and
Write modes, to suit the various CRT displays.
●
Associated with an easily programmable character height, the internal PLL generates the
programmable pixel clock, without using a crystal oscillator, that defines the character width
making the device suitable for multi-sync applications.
●
A maximum of 640 characters, defined in the mask-programmable ROM, are distributed among
the 4 windows and displayed simultaneously.
