How do I configure a unused arria 10 xcvr into a low power state?

I have multiple transceiver interfaces each however I will only need to use one at a time depending on the situation. To reduce power I would like to place the unused interfaces into a low-power state. How do I do this?

I am using an arria 10 and serial lite 3.

thanks

Hi Ben, As I understand it, you are inquiring how to reduce the power consumption for some of the XCVR channels which are temporarily not used in user mode. These channels are instantiated in the design and will be turned ON when it is needed without re-programming the device. If my understanding is correct, for your information, you may hold these XCVR channels in reset mode to reduce the power consumption. For Native PHY design, you would just need to assert the reset to the reset controller which will then put the PMA and PCS blocks of XCVR in reset mode. When you need these channels, just release the reset. Please let me know if there is any concern. Thank you. Best regards, Chee Pin
