1) Values are for TJmax = 150 °C.
2) AC characteristics for EBU pins are valid for 2.5 V ± 5% and 3.3 V ± 5%.
3) In applications where the LVDS pins are not used (disabled), these pins must be either left unconnected, or
properly terminated with the differential parallel termination of 100 Ω ± 10%.
