madmartigan 0 Posted October 9, 2011 Share Posted October 9, 2011 Hi all, I would like to install the crystal that came with my EM430F6137RF900 development kit. I check the hardware reference design for this board and it says to install the crystal near this giant solder blob on the board. The labeling Q2/Q3 isn't entirely helpful either, because there doesn't appear to be a convenient pair of holes to solder the crystal into, and the crystal DOES have 2 wires sticking out. I found some youtube videos of installing a crystal on a board (not the EM430F6137RF900), and the crystal was just soldered onto the board right on the solder blob. This is quite confusing for me, although the packaging looks entirely conductive. I am not an analog guy, and I don't know crap about board design, or how crystals work. Does anyone have an idea how the crystal should get soldered to this board? FYI board design can be found in SLAU278F p. 117. Much thanks! Quote Link to post Share on other sites
gordon 229 Posted October 9, 2011 Share Posted October 9, 2011 The BOM says it's supposed to be an SMD crystal, so chances are it is one. Sadly, I can't find anything on the recommended one (ASX-531), but I suppose it's similar to the Micro Crystal one the LaunchPad comes with. If you can lay it flat on a flat surface, it is one . Fig. B-54 in [tipdf]SLAU278[/tipdf] also suggests this to me. Look for "solder launchpad crystal" on YouTube, there are some, they'll show you the business. Quote Link to post Share on other sites
PentiumPC 119 Posted October 9, 2011 Share Posted October 9, 2011 I believe it is a SMD Crystal, does this make sense to you? Quote Link to post Share on other sites
gordon 229 Posted October 9, 2011 Share Posted October 9, 2011 Oh, it's not even Q1 which I was looking at :mrgreen: (To OP: details don't hurt... I take that back. The detail was in the post title :oops: ) Yeah, Q3 is more or less the same as the LP one, so the numerous YouTube videos will help. Quote Link to post Share on other sites
