Honored ContributorHow to output 10G clock
Hello,
i would like to transmit a 10G clock so as to use it as a trigger to another lab equipment through the fpga high speed transceivers. I tried sending "1010101010..." to a transmitters parallel port at 10000Mbps but the transmitted output is 5Gbps, not 10. Any idea to achieve this?2 Replies
Altera_ForumHi evanchat,
Due to the 101010 data pattern, your frequency will be half'ed. Ideally to output 10GHz clock, you would need to transmitter 101010 data pattern at 20Gbps. As I understand it, you might need to use Stratix V GT to achieve this 20G data rate.- Altera_Forum
Hi evanchat,
Just to add on regarding the Stratix V GT. To be able to output 20G data rate, you would need to use the GT channels with Low Latency PHY IP. This will put the transceiver channel into PMA direct mode (direct core to PMA block interface).
