DC/DC Converters
The on-board DC/DC converters deliver the following voltages
(depending on set execution):
•
+5V-STANDBY, permanent voltage for the Stand-by
controller, LED/IR receiver and controls.
•
+3V3, supply voltage for Keyboard
•
+12V, input from the power supply for the panel
common(active mode)
•
+12V, input from the power supply for the AMP
•
+1V2, from the power supply for the scaler IC MT5561
•
+1V5, supply voltage for DDR2 ( diagram B03B)
•
+3V3, genenal supply voltage
•
+3V3-TUN, supply voltage for tuner
•
+5V-USB, input intermediate supply voltage for the USB
Power
•
+3V3, from the power supply for the scaler IC MT5561
•
+1.1V, clean voltage for Demod channel decoder
