Description

WT6802 is designed to interface with a MCU to do the OSD (On Screen Display) function in CRT Monitor, besides the fancy auto-calibration function is also included.


The on-chip PLL generates a wide-ranged system clock up to 60MHz to meet the resolution requirements(OSD resolution is programmable) of different display modes. The full OSD screen size is 30 columns x 15 rows, and the OSD position can be freely programmed by setting the interal registers. Special functions include color font, character bordering, shadowing, blinking,double height, double width, all blanking effect, row to row spacing control, 4 windows with shadowing, and programmable fin in/fan out effect.


WT6802 has 8 channels of PWM DAC, each PWM DAC can be respectively controlled by an 8-bit register which contains a 5-bit PWM and 3-bit BRM, and the PWM clock is also programmable.The horizonal back/front porch and vertical black/front porch data can be read by MCU through the I2C bus in order to do the horizontal size/center and vertical size/center auto-calibration.
