TUSB522P: TUSB522PIRGER Schematic Review

Hi,

Here is the schematic review: TUSB522p_Schematic_Review_Faurecia_NA_NA (10_6_2026).pdf

Hi,

Pins 8,9: OK

Pin 11,12: OK

Pins 22,23: ESD diodes implemented. Please ensure that the clamping voltage of the ESD diodes does not exceed the abs. max voltage rating of the pins of TUSB522p. Recommended implementation is to have a 0201 0-ohm series resistor between the TUSB522p and ESD diode for ESD tuning. 

Pins 19,29: ESD diodes implemented. Please ensure that the clamping voltage of the ESD diodes does not exceed the abs. max voltage rating of the pins of TUSB522p. Recommended implementation is to have a 0201 0-ohm series resistor between the TUSB522p and ESD diode for ESD tuning. AC coupling these pins is optional. I recommend these optional capacitors as it may improve interoperability. The AC coupling on these pins should be 330nF. 

Hi,

Could you please clarify the statement, "The AC coupling on these pins should be 330 nF"? Does this requirement apply only to Pins 19 and 20, or should the AC coupling capacitors on all differential pins (8, 9, 11, 12, 19, 20, 22, and 23) be changed to 330 nF?

This comment only applies to pins 19, 20.
