Hello. What should be done with the REFB+/- and ZD_IN+/- inputs if they are unused? How about unused OUT+/- pins? Thanks.
"Unused input pins" I assume you must be using single-ended CMOS mode. In this case the unused input can be left open since t he circuits will be powered down by SPI register settings.
Output pins can be left open and powered down by SPI register settings.
The unused pins I'm asking about are REFB+, REFB-, ZD_IN+, and ZD_IN-. I'm using REFA+ and REFA- as the reference input so REFB+ and REFB- are unused. Also, I am not using the zero-delay inputs ZD_IN+ and ZD_IN-.
The unused input pairs can be left open and there is a register bit to power down the entire receiver or channel in the case of an output.
