AD9524 Unused Inputs and Outputs

Hello,

"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.

Regards,

Matt

Matt,

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-.

Hi Andy,

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.

Thanks,

Matt

Matt,

Thanks!

Andy
