STV9936P/S

General Description

The STV9936 is a new On-Screen Display (OSD) device with multiple menu displays for monitor

applications.

In addition to the standard features of an OSD, the special features of the STV9936 are listed below:

Simultaneous display of up to 4 menus anywhere on the screen. Each of the 4 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 704 characters, defined in the mask-programmable ROM, are distributed among

the 4 windows and displayed simultaneously.

The STV9936 introduces a new “Multi Windows”

concept allowing you to display and program up to

4 color-boxes independently, with overlapping and

priority management.
