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.
