You could also use a bandpass filter and let the harmonic frequencies get trough. The output of the Si5351a is a square-wave, so lots of odd harmonics available.<br />MilanAnonymoushttps://www.blogger.com/profile/06285222970418041156noreply@blogger.comtag:blogger.com,1999:blog-8490301272458780061.post-65842426322169544452015-09-22T17:16:34.208-07:002015-09-22T17:16:34.208-07:00In your work with the Si53531a were you able to ge...In your work with the Si53531a were you able to get it to go to 200Mhz. I see a lot of work with it but always seem to be limited to 160Mhz. I don't know if it's just the fact they haven't figured out the register values to do it or what.MikeinGVhttps://www.blogger.com/profile/12982884087814446589noreply@blogger.comtag:blogger.com,1999:blog-8490301272458780061.post-83282535515675021862015-04-27T23:34:57.358-07:002015-04-27T23:34:57.358-07:00Thank you Kevin,
