TUSB1310A USB3 Tx Rj

Other Parts Discussed in Thread: TUSB1310A

Hello,

Could TI please provide the USB3 PHY Layer Compliance Test Report for TUSB1310A ? We are testing TUSB1310A and need to compare results to the expected. We are observing high Tx Rj jitter component. We are using 40MHz xtal with SSC enabled, so the errata regarding Rj should not apply.

Hello,

Actually we do not have these teste report, sorry for that.

Please let me know if there is something else we can help with.

Hello Gerardo,

Could you please provide the TUSB1310A characterization data for USB3 Tx Rj (transmitter random jitter)? Ideally this would also include any mode dependencies such as TX_MARGIN[2:0] and TX_SWING in case we can optimize the Tx Rj by adjusting TUSB1310A settings.

KT

Hello Gerardo,

Do you have a loaner TUSB1310A evaluation board or internal validation board you can send us for short term use for USB3 Tx compliance testing? We need to have a baseline set of jitter measurements of the TUSB1310A to compare against our implementation in order to validate that we have not degraded the TUSB1310A jitter performance.

KT

Hello KT,
Unfortunately we currently no have a evaluation board. Please let me know the Xtal frequency you are using.
