Is there any PWM chip that can adjust the phase? [Copy link]

My requirement is to have two PWM pulses with the same period but different pulse widths. They have a front-to-back relationship when working, with A in front and B in the back, and the interval can be adjusted. The frequency can be adjusted from 120K to 10K. Currently, I use a single-chip microcomputer to use two timers to output PWM, and use one timer to control the interval, but the interval is 5 microseconds to 30 microseconds with an accuracy of 5 microseconds, which is very inconvenient (not very accurate). Does anyone have a better solution or any advanced timing chip available?

I remember TI's C2000 series has such a chip

Thank you, do all motor control products have this function?

Servo motor control solutions seem to have this

If it is done with CPLD or FPGA, it will be completely accurate if ns-level transmission delay can be tolerated.
