STV9936P/S General Description General DescriptionThe 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.
