Generate shifted PWM

Question asked by marco73it on May 29, 2017

I need to generate two PWM signals (frequency 6.78MHz, duty cycle 50%) that must be shifted by an amount programmable on-line by the user (the chip will be interfaced with a microcontroller and must be programmed on-line).

The PWM shift resolution (minimum shift between the two signals) must be at least 18-20 steps between 0° (signals in phase) and 180° (signals in opposite phase).


On the web I found the IC ADP1046A. However I am not sure if this component meets my requirements (maximum frequency, maximum PWM shift resolution) or if other ICs exist that are more suitable for the task.


Thanks for your support.

Best regards.
