TUSB1002A: May you pls help check TUSB1002A circuit?

Hi,

SSTX AC coupling value should be 220 nF and SSRX AC coupling must be 330 nF. Please make sure that there is not additional AC coupling on page 29. 

Dear David

I use the TUSB1002 as USB3.1 re-driver.

Below diagram, host and device is right direction?

1. EN can be left unconnected or tied to a 100nF capacitor to GND.

2. Leave MODE pin unconnected for USB operation.

3. For DCBOOST, add a pull-up resistor of 400 kΩ to add +1 dB of DC gain, as specified in Table 3 of datasheet. Sampled after rising edge of EN (See Figure 2 in datasheet). Leave pin unconnected for no additional DC boost needed.

4, C1234 and C1233 change to 0.22uF

5. C1235 and C1236 change to 0.22uF

6. C1238 and C1239 change to 0.33uF.

Thanks

David

Dear David

Follow your suggestion, I modify circuit.

Please, help me review the attachement circuit, thanks.

Please change C498 and C499 to 0.22uF, otherwise the schematic looks good.

Thanks
