A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to increase and cause the PLL to unlock when the temperature delta from the time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V (or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC VCO. The protocols only using Ring VCOs are impacted. Workaround: For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need to use alternate serdes protocols. Alternate option has the same functionality as the original option; the only difference being LC VCO rather than Ring VCO.
