    Hi Yohan, Have you seen the antenna selection guide? www.ti.com/lit/swra161 As you can see on page 28, the inverted F-antenna (DN007) is preferred over the meandred inverted F-antenna. /Fredrik

    Hi Per, It's a single audio (mono). Typically one slave, but sometimes two may happen. Considering raw PCM16 so far because of quality. Sounds like the dipole antenna is a very bad idea. But what about that minimum track length from balun till antenna without the SMA connector that I've...

    Gilson Fonseca
    Hi, I'm designing a wireless audio link with CC85XX devices. Due to limited range requirement, same room maximum 10m distance, I was wondering if a solution without the CC2590 could be enough. However, it may be a crowded place with 8 or 10 persons in the middle. Would that work fine? Also...

    Hi, I know MAX1811 is only a liion charger,so I use a dc stabilized power supply instead of battery.But I still can only program the device unless the voltage is behind 3.0v. I have checked my pcb many times ,but I can't find any problem.Now I can program the device behind the voltage of 3V,and...

    Thanks for your reply, In fact ,I have only one cc debugger.So it is hard for me to use the ppw commander to test the TX.I think a cc85xxdk-headset will help me a lot,but I am just a student.Ican't afford such kit even another cc debugger.Now what I can do is only check the sch and pcb again and...

    Thanks , This is my gerber files. (Please visit the site to view this file) I also take a picture for you. (Please visit the site to view this file) You mean there is a shortcut between the ground pad of cc8520 and the vias in the pcb?

    Thanks for your reply, The suggestion that you gave me is really hepful. But our lab don't have a spectrum analyzer and other rf measuring instruments.So I am not able to finish testing something that you suggest me to do.I only test the frequency of the crystal (48.002MHZ,47.9947MHZ),dcoupl voltage...

    Thanks, After few hours of work,I am sure all the VDD pins get the right voltage.And then I found the problem changed.That's my log file. (Please visit the site to view this file) But I still can finish the download behind 2.7v.I am wondering maybe there is some problem in my sch. (Please visit...

    Torje Nikolai Thorsen
    Hi, We are using the CC85XX-CC2590EM reference design, and trying to copy it as precisely as possible. However, we need to change the SMA antenna connector to a smaller IPEX antenna connector. Are there any known problems related to this kind of modification of the reference design? Best regards, Torje...
