All manuals and user guides at all-guides.com On Screen Display Controller The IC802 on video board is designed for display the built-in characters or fonts onto monitor screen. The display operation is by transforming data and control information from micro controller to RAM through a serial data interface. Pin2 is used to control the internal oscillator frequency by DC voltage input from external low pass filter (R830, C817, R833) and filter (R832, C818) is used to regulate the appropriate bias current for internal oscillator the resonate at specific dot frequency.
