Transceiver Native PHY clock and data width

MaCo

Hello, I configured the Transceiver Native PHY for a Cyclone V GX design to 2500 Mbps and enabled the simplified data interface so that I get a 32 bit data interface for tx and rx. The measured clocks (rx_std_clkout and tx_std_clkout) of the PCS interface have 62.5 MHz. 62.5 Mhz * 32 bit is not equal to 2500 Mbps. What am I doing wrong or what am I missing !?!?!?

Hi,


It could be due to 8b/10b encoding. For 32bit, there will be 40bits and 62.5*40 = 2500.


Hope it clarifies now.


Thank you,

Hi Intel guys,

just a remark, I can't press the "Accept as solution" button using Firefox under Ubuntu 2020.2 LTS, got only an error message.
