COMPONENTS DESCRIPTION

Outputs 5.0V. Power supply for D5V, FL+B and USB5V.
Outputs 1.27V.
Lo when detection voltage goes below 3.6V.
For installer memory and ROM correction.
Controls FM/AM tuner, the changer, CD mechanism, USB, panel, volume and tone.
Controls logic for muting.
Overcurrent protection of USB power supply
When pin1 goes Hi, USB5V is ON.
Controls the source, volume and tone.
Reference supply for 4V pre-out.
Amplifi es the front L/R and the rear L/R to 50W maximum.
Decodes RDS signal.
For CD and USB source.
For iPod authentication.
For CD source.
L.P.F.
Outputs 5.0V. Power supply for D/A converter.
Outputs 3.3V. Power supply for 3.3V.
Converts 3.3V to 5V.
Decodes MP3 or other fi les of audio/decompression standards by software based
architecture.
Converts 5V to 3.3V.
SDRAM for SOC.
NOR fl ash ROM for SOC.
Outputs 1.8V. Power supply for SOC.
When Q16's base goes Hi, A8V AVR outputs 8.0V.
While BU is applied, BU5V AVR outputs +5V.
When Q7's base goes Hi, Servo+B AVR outputs 7.5V.
When Q17's or Q21's base goes Hi, SW14V outputs 14V.
Outputs 20V when BU is over 20V.
When Q18's base goes Hi, ILL+B outputs 10.5V.
When Q14's base goes Hi, SW5V outputs +5V.
The base goes Lo, PAN5V outputs 5V.
When Q50's base goes Hi, AVR outputs 14V.
When the base goes Hi, Q51 is turned on.
When P.CON output voltage decrease is detected, output protection is made.
When P.CON SW is ON, malfunction of Q58 is protected.
When Q53's base goes Hi, P-ANT SW outputs 14V.
When the base goes Hi, Q57 is turned on.
When the base goes Hi, BU DET is turned off.
When the base goes Hi, Q60 is turned on.
