LMH1297: SDI_OUT+/- disable register

Hirokazu Takahashi
Expert 8420 points
Part Number: LMH1297

Hello Support team,

Could you please support below?
(1) I would like to know the register and setting values for disabling the output of the SDI_out +/- terminal.
(2) When SDI_OUT+/- is in disable, is it possible to make the SDI_OUT +/- terminal open?
(3) If SDI_OUT+/- can be disable with any register configuration, is the current consumption same value as IDDTRANS_EQ 205mA and IDDTRANS_CD 225mA in datasheet?

Best Regards,
Hirokazu Takahashi

    Hi Takahashi-San,

    1). Please refer to the LMH1297 programming guide section 3.15.3 for the recommended settings.

    2). Yes you can leave these pins as NC(No Connection) when SDI_OUT is disabled through pin or register.

    3). Yes your understanding is correct.
