Re: Si570 Set Frequency

Hi Alfredo -

First off, let me admit to zero knowledge about the Si570.

I think it unlikely that the device could get anywhere near to 4850MHz
(=4.85 GHz). I suspect that is a typo.

I do note from https://ko7m.blogspot.com/2014/04/si570-programming.html
<https://ko7m.blogspot.com/2014/04/si570-programming.html>that the start up
frequency of the device is 56.320MHz, roughly a factor of ten off of this
number.

I suspect these numbers are critical but should really be 45500KHz to
56700KHz. Those would realistically reflect the frequency range of the
DCO.
