FAQ

What is the function of the VBB pin?

The VBB pin provides an internally-generated voltage supply used as a switching reference for single-ended inputs or to rebias AC-coupled inputs.

How does the reset pin operate?

The reset pin is asynchronous and is asserted on the rising edge, allowing for the synchronous use of multiple dividers in a system.
