ref. clock) makes contact with AMC front panel.Grzegorz KasprowiczGrzegorz Kasprowiczhttps://ohwr.org/project/fmc-adc-130m-16b-4cha/issues/6Front panel cuts for MMCX connectors are too small2019-02-12T10:43:02ZDaniel TavaresFront panel cuts for MMCX connectors are too smallNeed larger cutout to allow easier insertion of MMCX cables.
Instead of a circular hole concentric with each MMCX connector, a
contiguous cut for all 3 MMCX could solve this issue.Grzegorz KasprowiczGrzegorz Kasprowiczhttps://ohwr.org/project/fmc-adc-130m-16b-4cha/issues/4OFA (overflow) and CLKOUTA pins are inverted at IC15 (buffer)2019-02-12T10:43:01ZDaniel TavaresOFA (overflow) and CLKOUTA pins are inverted at IC15 (buffer)Grzegorz KasprowiczGrzegorz Kasprowiczhttps://ohwr.org/project/fmc-adc-130m-16b-4cha/issues/3Open Hardware License notice2019-02-12T10:43:01ZDaniel TavaresOpen Hardware License noticeAdd explicit Open Hardware License notice to PCB silkscreen.Grzegorz KasprowiczGrzegorz Kasprowiczhttps://ohwr.org/project/fmc-adc-130m-16b-4cha/issues/2Deterioration of ENIG finishing2019-02-12T10:43:01ZDaniel TavaresDeterioration of ENIG finishing![](/uploads/22ec0bdd8afa5168555766909b425116/enig_deterioration1.jpg)
