I need a part to complete a USB - DMX converter

[Floydey]

I am attempting to make the USB-DMX512 converter featured in the September 2006 issue of Elecktor but am having trouble sourcing the surface-mounting Murata 6MHx resonator, type CSTCR6M00G53-R0.

 

The only supplier I can find is Farnell, who sell it in batches of three but specify a minimum order value of £20.00.

 

Any help would be much appreciated.

Since CPC are part of the farnell group surely you could give them a call, afaik they have no minimum order !!

Do you have a link for the article on the internet at all? Or something similar?

 

I would not mind having a go at making one of those if I get a spare minute.

Sometimes it is necessary to buy some other bits too, to make up the value! -Solder, XLRs, .......

 

Actually this is prob the main reason I never make these "projects" - something is difficult to source!

The Farnell £20 minimum order value is for free delivery ... the item is not stocked by CPC.

Maplins has one 6Mhz crystal in thier book RN14Q

if that is any help.

Without seeing the schematic, the resonator is probably just a low cost crystal substitute, so you could probably use a 6MHz crystal, with the proviso that it may not be surface mounted, and thus will require a bot of drilling and patching to fit.

The part in question has a built in capacitance so you would need to replace it with a crystal and two capacitors which could start to take up a fair bit of space and be very fiddly depending on the layout of the PCB. To be honest I'd be tempted to bite the bullet and place a Farnell order, either make it up to £20 or pay for postage.

 

Sorry I'm not much help.

Hey

 

Yeah you would need 2 capacitors of the right values to go with a crystal.

BUT you should be able to find a 6MHz resonator somewhere else, I can't imagine that it has to be a Murata resonator to function.

 

RS (http://rswww.com) sell them - though they might have a minimum order too.

CPC have 6MHz resonators, just do a search on the CPC site

[Floydey]

Thanks for your comments. The project is based around a pcb that fits inside a 3-pin XLR so it has to be the specified surface mounting resonator.
