4.6.1.1. How to Determine the TX PLL Your FGT Channel is Using

Withi each FGT PMA, thee ae thee TX PLLs which ca be used to clock the tasmit data. These TX PLLs ae Fast, Medium ad Slow ad geeally efe to the speed of you tasmit lik. I ode to detemie which TX PLL you FGT PMA is usig, pefom the followig steps:
  1. Ope the <poject_diectoy>/<desig_ame>.sy.pt file.
  2. Seach o the followig stigs:
    1. _syth_lc_fast_e
    2. _syth_lc_med_e
    3. _syth_lc_slow_e
  3. You ca detemie which TX PLL is eabled fo you chael by locatig a stig simila to the oe below:
    ; z1577b_u_ux_quad_3__ux2_syth_lc_fast_e                         ; eable
    I the example above, the Quad3, Chael 2 is usig the Fast TX PLL
