Other Parts Discussed in Thread: TS3A227E,
I have 3 questions;
1. Specification
In description of table 2 OMTP, is pin configration wrong?
I think sleeve pin is ground.
2. headphone information for noise
Do you have information that some headphone has noise(floor noise)?
(Is there any information that causes noise for wrong detection regardless of whether or not the insertion is slow?)
3. How to calculate resistor for noise reduction
According to specifiaction, delay time can adjust to change resistor at DET_TRIGER line.
Please inform how to calculate resistor.
specification only said please adjust it from real data. please inform formula.
Our customer said that some headphone has noise(it has like floor noise).
I investigate root cause, then I confirmed wrong detestion by slow plug-in by our DUT.
I'd like to know do you have similar issue( regardless of whether or not the insertion is slow) and countermeasure.
