3.4. RZQ Pin Migration Guidelines
This table describes the design migration guidelines for the RZQ pin for banks 3[A, B, C, D].
|Pin||I/O Bank||Board Design Guidelines|
|RZQ pin||3A||The RZQ pin for the bank 3C at the HF35 package of the Intel® Stratix® 10 GX400 or SX400 device must always be connected to GND, and it in not migratable to the HF35 package of the Intel® Stratix® 10 GX650 or SX650 device or vice versa.
When using OCT for the banks 3A, 3B, and 3C, connect these pins to GND through either a 240-Ω or 100-Ω resistor, depending on the desired OCT impedance.
For more information about the OCT schemes, refer to the Intel® Stratix® 10 General Purpose I/O User Guide.
When you do not use these pins as dedicated input for the external precision resistor or as I/O pins, leave these pins unconnected as recommended in the Intel® Stratix® 10 Device Family Pin Connection Guidelines.
