ISOUSB111: Redriver for USB Full-Speed

Part Number: ISOUSB111
Other Parts Discussed in Thread: ISOUSB211

Tool/software:

Hi team,

My customer is looking for USB redriver for driving long cable connection up to 10m.

They need "Full" speed redriver, but it seems that there is no redriver device(TUSB2xxx) for full speed(only high speed is compensated).

While, ISOUSB111 has repeater function for full speed in addition to isolation.

Is ISOUSB111 effective as redriver for "full" speed signal?

Or is there any other recommended device?

Best regards,

Shota Mago

    Hi Mago-San,

    Thanks for reaching out.

    Yes, the ISOUSB111 is effective as a USB re-driver at low speed and full speed signal.

    The ISOUSB211 is the device which supports High Speed USB Signal.

    Now coming to the Cable Length: The ISOUSB devices are compliant till 5metres of cable length as dictated in the USB Standards

    So if you want to use use the ISOUSB111 for 10metres(and if this length in non negotiable), you can use 2 ISOUSBs at 5 meters distance from each other.
