Other Parts Discussed in Thread: TMS320VC5509A
I am looking for TMS320VC5509A DSK BOM (Bill Of Materials) to find the 3.5 mm jacks' part numbers and their footprints.
In my designs, I always use 5-pin 3. mm jacks like the images below:
In addition, related to the file, I have attached to this, we can see that there are many types of sound jacks with different schematics and different pin assignments. I want to know that what is the main rule that tells us which pins of one Jack could be used instead of another Jack's pins. For example, the pin number 1 in jack J1 is equivalent to pin number 5 of jack J2.
What is the rule?
