3. TECHNICAL BRIEF
- 54 -
LED,VIBRATOR CONTROL
It is possible to synchronize an LED and vibrator with a play, and to control. Asynchronous control
With a play is also supported. It supports 3 color LED control and it is possible to display 7 colors In
maximum.
CLOCK GENERATING BLOCK
This device supports a clock input ranging from 1.5Mhz to 27Mhz.
It is a block to generate a clock which is needed inside of LSI in the PLL.
DAC
It converts digital signals from a synthesizer and a digital audio section into analog signals.
Its resolution is 16bits.
ANALOG LINE INPUT SECTION(EXTIN,RXIN)
External audio signal and receiver audio signal are inputted.
There is a Volume to adjust the level in each.
MIXER SECTION
Selection of an input source(DAC output, RXIN, and EXTIN) against each analog output(SPOUT,
HPOUT,EXTOUT,TXOUT) and mixing are performed.
EQ AMPLIFIER SECTION
The change of filter characteristic and gain is possible by adjusting the resistors and external parts.
SPEAKER AMPLIFIER SECTION
The two digital speakers amplifier, which has a maximum output power of 500mW at SPVDDL/R=3.6V
and RL=8ohm, is integrated in this device. There is a volume to adjust output level in the first stage of
amplifier.
HEADPHONE AMPLIFIER SECTION(HPOUT)
This is an amplifier for stereophonic headphone(RL=16ohm)output.
When it is used as a monaural output, Rch becomes power-down.
In the previous part of it, there are a volume and a bass-boost circuit.
EXTERNAL OUTPUT AMPLIFIER SECTION(EXTOUT)
This is an amplifier for external output(RL=600ohm)
In the previous part of it, there is a volume to adjust the output level
ANALOG LINE OUTPUT SECTION(TXOUT)
This is monaural line output(RL=10kohm) There is a volume to adjust the output level.
