CC2538: CC2538 + CC2592 2-layers Layout Review

Part Number: CC2538
Other Parts Discussed in Thread: CC2592

Hi all,

I have designed CC2538 + CC2592 module. The schematic is below:

I need everyone help to review the 2-layers layout.

This layout is designed on FR-4 PCB, 0.8mm board thickness, 53um copper thickness. I use the Saturn PCB tool to calculate the impedance of antenna trace below:

And these are the TOP, BOTTOM and 3D layer. Can everyone take the time help to review. Thank all so much.

    Hi,

    It looks Good except the following minor issues.

    C18 & C19 must be 1uF.

    C8 must be placed near Pin-43 ( you may move the crystal a little far to make the room for C8).

    Pins 13, 14 & 15 on CC2592 can be shorted together (Please see Ref design - SWRC286 ) and use One single trace to feed them

    Thanks,

    PM

    Hi TI supporter,

    I have fixed these issues which is recommended by you.

    The Gerber has already sent to FAB. I will report the performance to you later.

    Thank you so much.

    Hi  

    I am also working on CC2538+CC2592   2 layer board but by board thickness is  1.6 mm FR4,  I was  going through your blog and  is curious to  know the performance of your board . What  is the maximum  range you are getting  with the board..  In my case if it keep the board about  0.5 mtr away from the sniffer i get a  RSSI reading of -25 dBm and if I place it next to the sniffer i get a reading of -8 dBm. 

    If I keep the TI reference board next to the Sniffer I get a RSSI reading of -1 dBm, so I guess some issues with my board ..   

    Look forward for your  reply 

    Regards
