Oscillator reference circuit for C6A816x?

Hello,

I need to get better ppm than crystal can provide and I would like to use oscillator instead.

Please, where I could find oscillator reference circuit  to replace the 27MHz crystal connected between DEV_MXI/DEV_CLKIN (A19) and DEV_MXO (C19).

Thank you very much,

- Robert

    Hi Robert,

    Unfortunately, we are using crystals for the 27MHz on our board.

    I found some of these 27MHz oscillator from Element 14 web site, here's the link,

    http://sg.element14.com/jsp/search/browse.jsp?N=204350+110143195&No=0&getResults=true&appliedparametrics=true&locale=en_SG&divisionLocale=en_SG&catalogId=&skipManufacturer=false&skipParametricAttributeId=&prevNValues=204350&mm=1002300||,&filtersHidden=false&appliedHidden=false&autoApply=false&originalQueryURL=%2Fjsp%2Fsearch%2Fbrowse.jsp%3FN%3D204350%26No%3D0%26getResults%3Dtrue%26appliedparametrics%3Dtrue%26locale%3Den_SG%26divisionLocale%3Den_SG%26catalogId%3D%26skipManufacturer%3Dfalse%26skipParametricAttributeId%3D%26prevNValues%3D204350

    See whether any of it fits your requriement.

    Thank you very much Poh.

    Actually, to find an oscillator is not a problem - I found eg http://search.digikey.com/us/en/products/ASEMB-27.000MHZ-XY-T/535-11127-1-ND/2624353

    I just want to be sure the circuit is correct as it is essential part of schematic. If it doesn't work correctly - board will not work.
