1. For PSI5 the maximum operating voltage is 16.5V as called out in the PSI5 technical specification (V 1.2 /14.06.07).

Depending on the sync supply voltage the sync pulse can be as high as 8 V above idle. To ensure the maximum operating

voltage of 16.5 V is not exceeded then the VSATS voltage should be limited to 8.5 V.
