LTC_OUT2 on pin 39 is a direct connection to the processor and optimized for direct internal
connection. When made available for external access we recommend a current limiting in line
resistor, DC decoupling and tie to GND for defined DC state.

Pin37 delivers an ITU/REC tri level video sync signal at project frame rate selectable in either
1080i/PsF or 1080P that can be matched in level to drive one or two 75 Ohm targets. For one sync
connection adding an inline resistor of 75 Ohms is required, to drive two in parallel 37.5 Ohms.
