Regarding to the holdover time on E810-XXVDA4T, I saw on the product spec that describe the high-precision oscillator maintains high accuracy during holdover (when the synchronization
source is not available), providing up to four hours with less than +/- 1.5 microsecond of phase error.
My question is : What is Intel's design idea and thoughts to define holdover time with 4 hours and not to implement more longer, cause I saw that some competitors design with 12 hours holdover time on PTP server
