TUSB211: TUSB211RWBR EQ adjustment qusetion

Part Number: TUSB211
Other Parts Discussed in Thread: TUSB216

Hi, Support Team

We have some question about TUSB211RWBR EQ adjustment, thanks in advance.

According from datasheet description, the EQ pull-down resistor needs to meet the following range.

If the resistor out of range, is it possible to cause damage?

Besides the pull-down resistor adjustment, are there any other pins that can be adjusted?

if any suggestion, Please advise me.

Thanks,

Best regards,

Lawrence

Instead TUSB211, I would recommend using TUSB216 which has more knobs to compensating signal quality than TUSB211.

Thanks

Having the resistor out of range would not damage the device, but you will not have the expected amount of equalization being applied to the USB high speed signal.

Thanks
