Can I assert the transceiver tx_pma_elecidle signal indefinitely on Intel® Arria® 10 devices?

Description

No, you should not assert the transceiver tx_pma_elecidle signal indefinitely on Intel® Arria® 10 devices.

Resolution

The transceiver tx_pma_elecidle signal is similar to an analog reset signal. Asserting analog reset signals indefinitely can degrade transceiver performance. You can read about this degradation in the “Unused/Idle Clock Line Requirements” chapter of the Intel® Arria® 10 Transceiver PHY User Guide.
