Only when the Multisync devider steps are 0,1 (7.5, 7.6 etc) there is no jitter. But when I enter 7.59 the jitter is back.<br />Does anyone recognise this behavior and maybe has a tip?<br /><br />Rob<br />PA0RWEAnonymoushttps://www.blogger.com/profile/03601197873054868453noreply@blogger.comtag:blogger.com,1999:blog-8044784353067686026.post-3164012357061992452014-10-09T10:32:50.144+01:002014-10-09T10:32:50.144+01:00I have one of these boards as well now.

One thing I figured out from the datasheet and tested last night, is that you can produce I/Q outputs directly provided you stick with integer dividers. The big question is of course phase/jitter noise but it sounds clean at 144Mhz in another receiver.<br /><br />Andrew VK3JBLvk3jblhttps://www.blogger.com/profile/00034905042545839675noreply@blogger.comtag:blogger.com,1999:blog-8044784353067686026.post-58938706464331977232014-10-06T02:05:01.583+01:002014-10-06T02:05:01.583+01:00I have one of Jason's Si5351 breakout boards. ...I have one of Jason's Si5351 breakout boards.
