AFE8000EVM: Decision making for implementing JESD204C or JESD204B

Part Number: AFE8000EVM
Other Parts Discussed in Thread: AFE8000

Hello, I am new to JESD204C.

(For references, I have experiences with JESD204B subclass 1/0 using Xilinx IP core)

I want to confirm my knowledge on JESD204C is correct.

Subclass 1 of JESD204B requires the sync signal with separate pins.

However, subclass of JESD204C doesn't require it. In the AFE8000EVM,

no pin of FMC connector is connected to the GPIO_C5, C6, V5, V6, E5, D5, T5, U5

(With my knowledge, these pins are used for sync pin according to your datasheet).

With this in mind, first I concluded that this EVM can use only JESD204c subclass 1.

But, later then, I noticed that GPIO pins in AFE8000 can be configured for sync in/out.

To implement JESD204B subclass 1 in the AFE8000EVM, which pins can be used for sync signal for interfacing ZCU102 board?

  • Hi James,

    As you mentioned the AFE8000 GPIO pins are reconfigurable, so any available GPIO pins can be configured as the SYNC pins. For choosing which pins to use you scan choose any GPIO pins that are connected on the AFE8000EVM and also available on the ZCU102. 

    Regards,
