Part Number: DS90UB953-Q1

Dear Sir,

In order to compensate the long cable loss, is it possible to  set more bigger EQ and Diff Voltage Swing for DS90UB953?

Best regards.

    Hello Tiger,

    This is not possible on the SER.

    However, on the DES you have the Adaptive EQ, which compensate automatecally for any loss on the transmission channel. 

    Please keep in mind, that you can't have more loss on the transmission channel than specified in our documentations. for example:

    at 1MHz -- max 1.4dB
    at 50MHz -- max 3.5dB
    at 500MHz -- max 9.5dB
    at 1GHz -- max 14dB
    at 2GHz -- max 21.6dB
