Hi Team,

Are the VDDO Output Supply terminals 11 and 15 tied together on the die or do they supply two separate outputs each?

Thank you

Hello Mark,

The VDDO pins 11 and 15 supply all the outputs.

Both pins require a external voltage, but you can tie the two pins together as shown below.

The VDDO pins require the following termination.

Please note that if the two pins are tied together, then only one filtering circuit is required.

Regards,

Hi Kia,

Is each VDDO pin connected to supply INTERNALLY separate output banks?
In other words, for example: could I supply 1.8V to Pin 11 so Q0, Q1 are 1.8V outputs and supply 3.3V to pin 15 so Q2, Q3 are 3.3V outputs?

Hello Mark,

You cannot provide different supply voltages to each pin. Both pins must be provided the same voltage.
