TUSB214-Q1: Eye Diagram TEST, EQ, DC Boost Seting

Hi,

Can you please share your schematic and layout?

Please see this app note, https://www.ti.com/lit/an/slla593/slla593.pdf, did you have the test fixture connected to TUSB214-Q1 before enable the source to send the test packet?

Thanks

David

I sent you an email last week.

Thanks

Pin No 4 (SCL/CD) Pin is not high.
High doesn't come out, what could be the reason?

Pin Status

BD69 : 3.3V check

Pin11 : Vreg  -> 1.8V out check

Pin5 : RSTN --> forced short and open(Reset)

==> Ping4(SCL/CD) Pin is not high.

Hello~

There is no update in the place you told me.

Please answer the above question.
How much longer do I have to wait?

1. Using the TUSB216 Test Board, the change in eye pattern operation was confirmed. --> OK

   -->  ECU to TUSB216 Test board : USB Eye-Pattern test

 
2. TUSB214 failed to check operation. --> I want a quick answer

  -->  ECU to TUSB214 : USB Eye-Pattern test  ==> Signal No Change..

Removed Tusb216 from Tusb216 board and used TUSB214 (use TUSB214 VCC: 3.3V)

I hope this gets resolved quickly
