TPS51206: Only VTTREF case

Genius 17145 points
Part Number: TPS51206
Other Parts Discussed in Thread: TPS51200

Hello,

I have 2 questions for TPS51206.

1.

My customer usually uses TPS51206 for DDR circuit.
But their new project requires only VTTREF and doesn't need VTT.
In that case, do we have any other better device than TPS51206?

2.
I have checked the below post for VTT unused case of TPS51206.

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/945053/tps51206-vtt-unused-case

Then I have an additional question.
Can the capacitor on VTT be removed in this case?

Regards,
Oba
