Now that my TIC is working with Bert's board, I'm considering taking the next
step of designing a GPSDO from scratch. There are several projects I'd like to
do with a dsPIC33, so that was a natural choice. But I now understand that it
has an audio DAC and is not recommended for process

Could someone explain to me how such an audio DAC differs from a non
-audio DAC and why it's not suitable for this application?=A0 Is this just
a disclaimer from microchip to avoid liability or is there

I think these kinds of DACs are meant to be clocked out at some fixed
sample rate, like 44.1KHz and your software has to stuff a FIFO so
there is some milliseconds of delay in the queue. Before you use
these write some pseudo-code and see if you can make it work.
One idea is to never write to

Hi
There are several reasons why they don’t recommend the typical MCU DAC for
control applications:
1) They are noisy at low frequency (1/f noise corner
