(1) P = output vouti_clk period in ns.

(2) All pads/balls configured as vouti_* signals are recommended to use slow slew rate by setting the corresponding

CTRL_CORE_PAD_*[SLEWCONTROL] register field to SLOW (0b1). FAST slew setting is allowed, but results in faster edge rates on

the VOUTn bus, higher power/ground noise, and higher EMI emissions compared to SLOW slew rate.

(3) SERDES transceivers may be sensitive to the jitter profile of vouti_clk. See Application Note SPRAC62 for additional guidance.
