AD9648 Rbias

Hello,

 

We are looking at using the  AD9648, and we can't find a description of the Rbias pin.  However, the eval board user's guide states:

 

 

RBIAS

RBIAS has a default setting of 10 kΩ (R206) to ground and is used to set the ADC core bias current. Note that using a resistor value other than a 10 kΩ, 1% resistor for RBIAS may degrade the performance of the device.

 

 

Is that true?

 

Thank you
