The 16V(F15V) from the P board via pin1-4 of connector A02 is applied to Analog ASIC
IC5000 and ICs (Voltage regulators) on the A board to generate the SUB-Voltages used for
signal processing operation.
: SUB1.0V, 1.8V, 3.3V, 5V and HDMI3.3V, TU1.8V
Each voltage regulators start up by high state of DCDCEN signal which is pull up to F15V.
So F15V is provided to A board, each SUB-voltage regulator ICs start output.
