收发器接收pin作为收发器的参考钟

HI,

Thanks for sharing customer design and I understand the issue better now.

By right fPLL should be able to accept refclk pin from another Rx pin but customer design will failed fitter compilation unless dedicated refclk pin is used as fPLL refclk pin.

Let me build simple example design to verify fPLL refclk connection then I will get back to you.

Another feedback to your customer is your customer tend to use "generate" function to duplicate transceiver channel count instead of setting the right transceiver channel count in NativePHY IP

• Pls advise your customer not to do it as it's very dangerous.
• It's easily prone to user design connection error and may also mess up NativePHY internal connection generation.

Thanks.

Regards,
