Part Number: TUSB212EVM Tool/software: I used the HS detection circuit on transistor Q1 .
When the VREG signal 1.8V appears, the LED does not light up. The LED itself receives a voltage of 1.4V. At the same time, the LED should have a voltage of at…
Hi Nadeem,
Are these two hubs the only two you have tested with? Have you tested any other hubs and have been unable to duplicate this effect?
On my side, I have tested this with one of our hubs being powered externally with a power source and connected…
Hi Jaden,
Ultimately, the distance that the TUSB212 supports will depend on the pre- and post-channel loss- of the system in decibels at 240Mhz.
The length measurements mentioned in the datasheet were near-end eye diagram measurements and were tested using…
Hi,
Since USB Hub is so close to the connector you may not need redriver to drive 1m cable. Have you done eye diagram test to confirm (measure after 1m cable)? If you care using TUSB212EVM you can place right after B with a short cable.
