Description
Reference B Input. This internally biased input is typically ac-coupled and,
when configured as such, can accept any differential signal with a single-ended
swing of up to 3.3 V. If dc-coupled, input can be LVPECL, CMOS, or LVDS.
Complementary Reference B Input. Complementary signal to the input provided
on Pin 47. The user can configure this pin as a separate single-ended input.
No Connection. This pin should be left floating.
Interrupt Request Line.
Configurable I/O Pins. These pins are configured under program control.
The exposed pad must be connected to ground (VSS).
