Re: SI5351 drive level

 

No shorts in the turns. I also re soldered the connections.

When I scope the transformer, I get 250mv p-p. Looks like one of the transistors is gone. I had it working for quite for weeks.

Checked my DDS setting drive source to 8ma,?crystal load to 8pf. Stuck a 50 ohm load on the o/p and I get 1.8v p-p.
