Descripción
INTRODUCTION The SAA4849 (FLASH version) is very cost effective CMOS deflection controller with integrated 80c51 CPU and extra port functionality like DDC, timers, ADC, PWM. The deflection controller and microcontroller are combined into one SDIP56 package. Performance improvements: • DAC instead of PWM to reduce noise Cost effective implementation: • I2C register readout in period versus frequency is cheaper because divider function of CPU can be used to generate frequency. • Horizontal focus is not implemented because most CRT monitor manufacturers use horizontal focus transformer instead of dynamic focus amplifier. • In case of combined deflection/EHT the HV adjustment can be done via I2C register h20. • Three ADC inputs that are multiplexed to only one ADC. • LED driver output saving 1 external transistor.
