Differential Serial Buffer IC

[Sparky5]

Hi All


I am currently looking for an IC that I can use to buffer a USB 2.0 signal. I am not looking to change the output voltage level or rearrange the data in any way. My goal is simply to reduce the jitter/error to an absolute minimum, differential in and differential out. I am looking for a serious about of buffering, something overkill that can run from 12 volts preferably.

If anyone knows of a commercially available IC that does exactly that, It would be very much appreciated.

Could someone please advise?

Thanks

May be help use a multiplexer/switch (always one output activated)
smthng like TS3USB221
Hope helps

Do you think this will keep data error stream errors to a minimum?

Hi;
This may only help to improve signal integraty, since it buffers signal again.
If you have trouble with the signal recovery at the receiver side -because of the path lenght, path capacitance etc.-, it might help.
Consider like a repeater.
Just an idea, not sure about it.

Yes I am going to add a differential repeater both at the input and output of this device. The buffer I was looking for would basically act as a PLL to make sure that a consistant stream of data was actually leaving the device. The overall goal is a clean data stream at the output.

I understand that the load will have some form of buffering inside already, my plan is to assume that it doesnt.
