Hi,
I am thinking of using the device to provide synchronization frequencies for different DCDC converters as well as a misc clock signal.
I would like to generate
1) Five phase locked and phase shifted clocks with 1.5 MHz
2) One phase locked and phase shifted clock with 750 kHz
3) One phase locked and phase shifted clock with 250 kHz
4) One simple 48 MHz clock signal, no phase relation required to the above
If I do the following:
- PWM3 : 250 kHz
- PWM4 : 1st 1.5 MHz Phase
and then use
- FPWM1/2 for two further 1.5 MHz phases
- FPWM3/4 for two further 1.5 MHz phases
- FPWM5: for 750 kHz clock (FPWM 6 is unused)
- FPWM7: to generate 48 MHz (which is too fast for PWM signals and require FPWM)
Would the phase relation between PWM 3/PWM4 and my FPWM(1..5) signals then be fixed, static and locked with every device restart ?
Reliable static phases on PWM3/4 would allow me to adjust my phase-shifts on my FPWM1..5 signals such way, that all their positive edges will never meet, and I run my converters as quiet as possible.
Thanks in advance and best regards.
