FEATURES

• PCM sound generation method provides realistic sound reproduction

- Contains 32 kHz sampling Wavetable, it include 128 GM tone and 47 drum set and 32 effect tone.

- A richer tone is achieved by using 2 Wave a tone.

- The wave and the parameter can be downloaded, and the sound-making not limited to a fixed tone is

possible.

- Can play up to four melodies because of four MIDITM ports that are embedded in the sound generator core.

- The port for a real-time control of MIDI that assumes karaoke and the JAVAapplication program is installed.

- Contains a digital parametric equalizer for equalizing speakers.

- The function for a low output of the level to always enable the reproduction in the vicinity of the maximum

volume is built into.

- Various sound effects (pitch pipe bend, vibrato, Delay, reverberation, chorus, Doppra, and compressor) can

be achieved.

- Supports MOBILE-XMF.

• Contains real-time-processing 3D positioning surround functions

- The effect of the sound that the sound source moves three-dimensionally by the digital signal processing

can be achieved.

- The stereophonic effect with the extension can be obtained by the digital signal processing.

- The programmable solid sound parameter is installed, and the best setting is possible in the case and the

speaker arrangement etc. of the cellular phone.

- When the headphone is used, the stereophonic effect can be obtained.

• Includes a high-performance D/A converter with 16-bit resolution

- Supports five sampling frequency (fs) modes: 8 kHz, 16 kHz, 32 kHz, 44.1 kHz, and 48 kHz

• Provides an audio serial I/O interface (16 bits).

- The serial data input frequency is variable from 32 fs to 64 fs (during slave mode).

- Supported formats are right-justified, left-justified, and IIS

• Provides an external serial input/output interface for the sound generator

• Provides stereo line output for audio

• Supports 8-bit parallel interface or 3 or 4-wire serial interface (SPI).

• Output control functions for vibration and LED.

• Built-in PLL, so various types of input clocks can be supported.

• Contains a regulator for digital power supply (DVDD).
