Hello guys. I am trying to develop a project that I made two years ago by soldering Tensy 4.1 and transfer it to Altium. I have added two images (111.png and fdfdfd.png) for you to understand the concept and usage of the first project. I am adding the schematic for the special Teensy board. This is my first post, so there may be some missing parts. I used SGTL5000 for the circuit and plenty of 4051 ICs for the controls. If there are any parts that can be added or errors you noticed, I would like your help.
Our new project will be like the last image. Finally, I will add a radar. I want it to be a programming card and device in every sense.
Do we have any predictions about whether this distance between Sgtl5000 and NXP will be a problem?
Schematic:
Are the 5 cyan colored traces MCLK, LRCLK, SCLK/BCLK, DOUT and DIN? Where are the traces for SDA and SCL?
I am not an PCB expert but I had a board where the layout of the traces led to noise from MCLK to the SDA line which caused some trouble. As far as I understand tracing high frequency signals (MCLK at 11MHz) in parallel closely together can be problematic. Ground plane can also play a role.
May I ask: Do you had any guidance how to lay out such a complex board? Did you do that all by yourself?
I am planning to start a board where I also would like to combine analog and digital parts (Teensy, SGTL5000, class D amp, LEDs, battery charger...) and I am bit worried to put all that together.
As you can see in the schematic, I basically used the schematic that Paul shared on the site and built the system around it and using the MIMXRT1060 EVAL BOARD as a reference. As an electronics engineer, I wanted to push my own limits. There will be costs and certain difficulties in the prototyping and debugging process.
When I used the Teensy 4.1 by soldering it to the board as in the first two images, many ICs were tested. I brought the modules to this point based on the reference schematics.
Since I used 4-layer and single-layer smd components, routing is difficult. I used GND via a lot to prevent noise. At this point in the design, the distance between SGTL and MIMXRT1062 scared me. Should I change the design, or wouldn't it be a big problem? I wanted to get your opinions.The I2C lines are going from the bottom.
