hi, 

 

there are some news said these days 

" 

Arria II GX FPGAs achive PCI-SIG compliance for PCIe 2.0 

... 

" 

 

To my understanding, the highest data rate of integrated  

transceiver of Arria II is 3.75 Gbps which is lower than 5.0 Gbps 

of the PCIe 2.0. 

 

What is the news meaning? Do i miss something? 

 

Thanks,

PCIe 2.0 is 5.0 Giga-transfers per second because there is a lane going each way between two devices. Thus, a clock speed of 2.5GHz is required to achieve this transfer rate, which is mighty fast but it falls within the range of the A2GX transceivers.
