Q
Which is the maximum value of the external clock for the PWM on ADuc848?
A
You can safely run it at up to 12.58 MHz, which is the tested maximum speed of
the core logic.
It may well work at higher rates - but we have not tested this and so we cannot
guarantee it.
In the opinion of our microconverter applications engineers, it is quite likely
that it will work
at up to 20 MHz but any risk in doing so belongs to the user and not to Analog
Devices.
