Hi all
i'm working on "Transceiver Signal Integrity Development Kit" with strativ V GX. i'v already worked with 10Gbase-R Transceiver phy with no problem, and i tested my design with an Ethernet analyzer Device. but i need to use Native Phy in PMA Direct mode, to use the line data for mapping in another protocol. in first step i tried to loop the rx data to tx data, to test the design with Ethernet analyzer, but it doesn't work, when tx data rate is 10Gbit/s, the rx data rate is approx. 8Gbit/s. indeed, rx data rate is always less than tx data rate. something is wrong, but i can't understand what is. i'v studied all altera documents about Transceivers and i'v reviewed the altera online training in this field. has anybody no idea about that. i can present more details about my design in case of need. even attach the project here. thanks a lot
