: A board (SUB voltage) >
The 16V(F15V) from the P board via pin1,3 and 5 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.
: SUB1.1V, 1.5V, 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.
