SATA Layouts needed
I do agree that the stackup is the most important, since the dielectric thickness is directly related to the differential impedance of the pair!
Why the substrate is so critical? Aren't they all using FR4?
Hi there,
I need SATA PCB layouts in GERBER, PDF or any CAD software. I am intending to add SATA HDD support to my OMAP via USB 2.0 interface. I am planning to use JM20339, but the manufacturer lacks of the PCB guidelines.
I would be thankful if you send/point to me any source of...
I have the kit too. What are the specific questions about it?
If you mean to clone the JTAG part - it is an FPGA design and Spectrum Digital does not provide the sources to implement the FPGA.

Look in these papers:

dsp/bios bootloader
Hi,
Does anybody of you have a C6711 DSP/BIOS Bootloader project? I’ve try to make it hundred of times but without success. After reading the TI’s PDF I wrote the bootloader without DSP/BIOS and it is running ok. Unfortunately it is not the same with the BIOS version.
The...
Asking the people from TI is a waste of time….
The board design is not a problem. Anyway you have to place a JTAG header on your PCB. I can tell you what I did. Currently I have a DSP, a voltage regulator, JTAG header. I also left space (not soldered yet) for a RS232 interfacing. The DSP is...
tms320c2812 board
I'm also building a board with F28xx.
There are some posts in the forum about programming f28 via RS232, but I still cannot do this.
The problem with the JTAG is very serious because it is expensive and you cannot debug the DSP without it. It does not matter what is the...
creating your own motherboard
Easy …. not at all !!!
It is easy to solder a BGA in some quantities. There are many small companies (even in Bulgaria) who will solder them if you pay for it :))
The point is when you have one produced PCB prototype and only one DSP sample. Well... now I have...
how to make my own motherboard
well, I've built one. It is exactly 133 SDRAM :) as johncsl82 mentioned, but it is not x86 compatible. it is based on a DSP - C6711 and it works fine. It has AC97 audio too.

vs1103 mp3
As far as I see. All of the models ST01X and VSXXXX are decoders. Just few of them have some ADPCM coders. Only VS1103 have Ogg Vorbis coder! Can somebody point to a real MP3 coder please?
I need to record an audio signal 24x7 in a very good quality.
I have my own design with...
c35 sms controller
I'm using the new version of this one:
https://tscommunication.com/
Their new version has 4 user inputs and 4 or 6 user outputs. The both are controllable via SMS
spread spectrum
There is an additional goal too. At the same time there can be many transmitters sending their own information in the same bandwith. The spread spectrum technique (based on the spreading pseudo-random binary string) can recover them all.
how to implement spi in dsk6713
Hi, I've spend several months running RS232 on DSK6711 (my own daugghtercard) and it is definetly though work. The pdfs from TI are quite not enough.
I recommend you to read about RTDX and implement this as a windows software (you only have to include and link a...
I need the windows software in order to understand and test everything. If you are going to use fabricated Bluetooth modules it is completely different case. They come with implemented software. I also suppose the manifacturer will provide something like SDK with examples. But in this case you...
