3.6.1. Clock Ports

The GTS PMA/FEC Diect PHY Itel FPGA IP suppots two clock output pots.

The two clock output pots ca each choose oe of the thee clock optios descibed i Clock Outputs.

tx/x_clkout

tx/x_clkout is a output pot that is eabled by default. You ca select oe of the thee clock optios descibed i Clock Outputs as the souce fo this pot, by selectig TX/RX Clock Optios > Selected tx/x_clkout clock souce o the TX Datapath Optios tab.

tx/x_clkout2

tx/x_clkout2 is a additioal output pot that you ca eable by tuig o the Eable tx/x_clkout2 pot optio i the paamete edito. You ca select oe of the thee clock optios as the souce fo this pot, by selectig TX/RX Clock Optios > Selected tx/x_clkout clock souce o the TX/RX Datapath Optios tab.

Both the tx/x_clkout ad tx/x_clkout2 outputs ca be futhe divided by a facto of 1,2, o 4.

i_tx/x_coeclki

i_tx/x_coeclki is a iput pot fo clockig the TX/RX coe iteface FIFO. Refe to Recommeded Coectio ad Souce fo the ecommeded coectios. The ecommeded souce clock fo o_tx/x_clkout ad o_tx/x_clkout2 whe coectig to i_tx/x_coeclki is show i Recommeded tx/x_coeclki Coectio ad tx/x_clkout2 Souce. The ecommeded pot coectios details ae show i Pot Widths ad Recommeded Coectios fo tx/x_coeclki, tx/x_clkout, ad tx/x_clkout2.
