Can the on-chip PLL be used to synthesize an external clock?
I'm trying to solve the following problem:
- Generate a 6MHz signal from a signal in the 60kHz range, +- 0.5%
- The reason for the 60kHz is that I want to use a uC timer to drive
the PLL. Running at 72MHz a 1000-count gives me about 0.1% of
So I need about a 64x or 128x PLL.
Probably more hassle than getting an off-the-shelf PLL.
