We are getting CRC errors with JESD204C IP

We are using JESD204C IP with E-Tile transceiver to interface Stratix 10 TX Signal Integrity Development Kit with TI ADC12DJ5200RF EVM for interoperability test report for Intel. We are observing CRC...

Hie,

My apologies but currently, there is no automation framework available for PMA tuning for Stratix 10 E-tile transceivers. This is because PMA tuning has a number of dependencies such as temperature, data type (different data types, idle character with stressed pattern produces creates different level of ISI), crosstalk between channels, noise coupling through PDN, reset and data release sequence.

Hence, thats why Stratix 10 offer Receiver adaptation but still recommend certain level of manual PMA tuning to determine the most optimum equalization value for both Tx and RX side. Typically, if the channel only has ISI with minimal crosstalk and PDN noise coupling, receiver equalization tuning (automated through adaptation) should be able to determine the automated settings.

Hence, you will need to perform PMA tuning as recommended in our user guide.

We will take this feedback to consider how to create a more automated framework.

Regards,

Nathan
