DP83TC811S-Q1: AVB protocol and INT function detection

Amelie Zheng

Part Number: DP83TC811S-Q1
Other Parts Discussed in Thread: DP83TC811

Hi Team,

May I ask two questions of 811?

Does the current DP83TC811 100M PHY support AVB protocol, or some protocols, such as IEEE802.AS (gPTP) protocol?
Is there any way to check whether the INT pin function is normal during production?
For example, after the SELF TEST function is turned on, INT generates an interrupt signal, allowing the master to detect this signal and determine that the INT pin function is OK.

Hi Amelie,

The DP83TC811 is capable of supporting AVB per our low jitter and latency by design.

Checking INT function can be doable as a test you would just need to make sure the register is configured properly based on your needs.

Thanks,

Cecilia

Hi Cecilia,

Thanks for your reply.

As for checking whether the INT pin function is ok or not during production, may I ask which Register should customer use?

Hi Amelie,

You can try using INT_TEST register.

Thanks,
