LMH0387 Equalizer sleep mode

Other Parts Discussed in Thread: LMH0387

If I force the equalizer into sleep mode by setting the control bits to "10", does that bypass the equalizer and I can still see toggling outputs (un-equalized input)?

Or, does that shut down the outputs as well?

Assuming that I have the driver turned on.

    If you force the LMH0387 equalizer to sleep by writing 10'b to bits 4:3 of register 0x00 as you describe, this disables the equalizer outputs as well, so there will be no output from the equalizer.

    The LMH0387 does not provide a mechanism to display the unequalized signal from the LMH0387 equalizer; the equalizer is either turned on and equalizing, or turned off and there is no output.
