Other Parts Discussed in Thread: TUSB2551, TUSB2551A, TUSB2036

Will the transceiver cleanup this eye diagram to allow meeting USB compliance?

    Jeff,

    The TUSB2551 may be able to help, but only if you are currently using an external transceiver already?  A transceiver is not specifically intended as a means to clean-up signal intgrety issues - it is the PHYsical layer of the complete USB device.

    Can you please describe the system implementationyou are currently testing?  If your system consists of a fully integrated single chip solution, then the TUSB2551A will not help.

    The image is difficult o amke out - what USB speed are you running at?

    Dan,

    From what you are describing, sounds like 2551 is not a solution for my application.

    Application is Stellaris LM3S9B96 C5 version embedded USB peripheral running at full speed.

    Thanks

    Jeff,

    Correct on TUSB2551A

    The TUSB2036 hub could be a potential option depending on your power arrnagement.
