Bob, No parts list except this one which you can use to get started : http://n4iqt.com/BillRiley/DMTDMixerModulePartsList.xls Spreadsheet file
or down load the free PCB express software and generate a parts list with them and files here : http://n4iqt.com/BillRiley/MixerModule_7.sch http://n4iqt.com/BillRiley/DDSModule.sch DDS board has the option for 4 distribution amps only 2 are used normally. PICTIC II board is used without the op amps and 7.5 volt regulator notes: http://n4iqt.com/BillRiley/No-interpolator.txt page 3 of this file has full parts list http://n4iqt.com/picticii/circuit-pcb.pdf If you install the interpolator it can be turned off with a software command. R25 a 10 K resistor only used with the TTL computer interface option, not used with the RS232 chip, is listed twice as 1% or 5% either will work but you don't need both.

Cool. Is there a parts list? I definitely want to build one. Looks like a really interesting project and a great opportunity for me to learn. I've been meaning to tinker with those AD DDS chips for a while. I have a dev kit for one of the models around here somewhere that I picked up for an ultrasound focusing project (sound radiation pressure was used to push blood cells to the center of a capillary tube) but all I really did was layout. No software for me on that one. -Bob On Tue, Sep 7, 2010 at 11:40 AM, Stanley Reynolds < [email protected]> wrote: > Yes this file: > > http://www.n4iqt.com/BillRiley/A-Small-DMTD-System.pdf > > Stanley > > > > ----- Original Message ---- > From: Robert Darlington <[email protected]> > To: Discussion of precise time and frequency measurement < > [email protected]> > Sent: Tue, September 7, 2010 11:54:56 AM > Subject: Re: [time-nuts] Small DMTD project PCBs Group Buy Update, boards > are > here ! > > Hi Stanley, > > I'm very interested in building this project.
