This Document can not be used without Samsung's authorization

2-2-3. IF connetor

It is 24-pin connector, and separated into two parts. One is a power supply part for main system. And the other is

designed to use SDS, DEBUG, DLC-DETECT, JIG_ON, VEXT, VTEST, VF, and GND. They connected to power supply

IC, microprocessor and signal processor IC.

2-2-4. Audio

AOUTAP, AOUTAN from CSP2200 is connected to the speaker via analog switch. AOUTBP and AOUTBN are connected

to the ear-mic speaker via ear-jack. MICIN and MICOUT are connected to the main MIC. And AUXIN and AUXOUT

are connected to the Ear-mic.

YMU762MA3 is a LSI for portable telephone that is capable of playing high quality music by utilizing FM synthesizer

and ADPCM decorder that are included in this device.

As a synthesis, YMU762MA3 is equipped 16 voices with different tones. Since the device is capable of simultaneously

generating up to synchronous with the play of the FM synthesizer, various sampled voices can be used as sound effects.

Since the play data of YMU762MA3 are interpreted at anytime through FIFO, the length of the data(playing period) is not

limited, so the device can flexibly support application such as incoming call melody music distribution service. The

hardware sequencer built in this device allows playing of the complex music without giving excessive load to the CPU of

the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for real time sound

generation, allowing, for example, utilization of various sound effects when using the game software installed in the

portable telephone.

YMU762 includes a speaker amplifier with high ripple removal rate whose maximum output is 550mW (SPVDD=3.6V).

The device is also equipped with conventional function including a vibartor and a circuit for controlling LEDs synchornous

with music.

For the headphone, it is provided with a stereophonic output terminal.

For the purpose of enabling YMU762MA3 to demonstrate its full capabilities, Yamaha purpose to use "SMAF:Synthetic

music Mobile Application Format" as a data distribution format that is compatible with multimedia.

Since the SMAF takes a structure that sets importance on the synchronization between sound and images, various contents

can be written into it including incoming call melody with words that can be used for training karaoke, and commercial

channel that combines texts, images and sounds, and others. The hardware sequencer of YMU762MA3 directly interprets

and plays blocks relevant to synthesis (playing music and reproducing ADPCM with FM synthesizer) that are included in

data distributed in SMAF.
