11. IC4512 (IXA595) QS-LCD-CONTROL
This is an LCD control IC for OS driving control that handles three-wire serial communication with the
MICON (IC3501).
It outputs a control signal for driving the liquid crystal panel.
Additionally, it has a Quick shoot image quality correction function (including control of the temperature)
and an OSD MIX function.
12. IC4701 (A706WJ) GRAY-LEVEL
This IC is a gradation reference power supply for a TFT liquid crystal display. It incorporates a gradation
output buffer amplifier (18 circuits), a COM buffer amplifier, and a REF amplifier (reference power supply).
13. IC3405 (NJU26150) SOUND DSP
This IC is a 24-bit digital audio processor.
It downloads the program stored in the E2PROM IC3407 to the built-in PRAM and then executes it.
Audio data input and output are performed through an I2S serial host interface. There are three data inputs
and three data outputs.
14. IC3406 (NJU26106) VIRTUAL DOLBY
This is the Virtual Dolby Surround IC, manufactured under license from Dolby Laboratories.
Audio data input and output are performed through an I2S serial host interface.
15. IC3203 (BH3543F) HP-AMP
This is the dual headphone output amplifier IC.
It incorporates a POP noise prevention circuit and a thermal shut down circuit (150°C) that work if an eror
occurs when turning the power on or off.
16. IC1623 (BA7046F) SYNC-SEP
This IC incorporates a video synchronous separation circuit, a vertical synchronous separation circuit,
a horizontal oscillation circuit, and a phase-comparison circuit. When a video signal is input, a composite
synchronous signal (SYNC), a vertical synchronous signal (VD), and a horizontal synchronous signal (HD)
are produced.
This IC has both synchronous separation and AFC (Auto Frequency Control) functions.
