ADCMP572 VTT pin confusion

We've received 2 ADCMP572 eval boards, but unfortunately the documentation for the part and the eval board seems to be inconsistent.

As a result, I have a question:  should VTT (pin 8) be tied to GND or pulled high? 


Per the part datasheet (pg. 6) it should be tied to VCCO, but on the eval board it is jumpered to the ground plane (APLANE) via P3, and that is listed as being the correct jumper setting (pg. 9).

  Thanks.
