High Speed Monolithic Pulse Width Modulator
Solution for clock period is shifted
In the printer or copier system, there are some possibility that clock period is shifted because
beam detect signal generates at the beginning of each pass across the paper.
If clock period is shifted one time, PWMOUT will be invalid. It needs long time to recover valid
PWMOUT after previous clock period inputted.
To settle above problem, beam detect signal take in to LS (16 pin) of M66244FP.
For this, It can recover valid PWMOUT within 4usec after previous clock period inputted.
Example of operating timing using LS function
