ML2240

4-Channel Mixing Oki ADPCM Algorithm-Based Speech Synthesis LSI

This document contains minimum specifications. For full specifications, please contact your nearest Oki office or

representative.

GENERAL DESCRIPTION

The ML2240 is a 4-channel mixing speech synthesis device which connects an external ROM expanded up to

128-Mbit (maximum). This ML2240 allows to select the playback method from the 8-bit PCM, non-linear 8-bit

PCM, 16-bit PCM, 2-bit ADPCM2, and 4-bit ADPCM2 algorithms. And the sound volume is adjustable as well.

The ML2240 incorporates a 14-bit D/A converter, and low-pass filter.

It is easy to configure a speech synthesizer by externally connecting a power amplifier and a CPU to the ML2240.

FEATURES

• Non-linear 8-bit PCM, 8-bit PCM, 16-bit PCM, 2-bit ADPCM2, and 4-bit ADPCM2 algorithms

• Serial input/parallel input selectable

• Phrase control table function i.e., user definable phrase control table function

• 4 channels mixing function

• Master clock frequency:

• Sampling frequency:

4.096 MHz

4.0 kHz, 5.3 kHz, 6.4 kHz, 8.0 kHz, 10.6 kHz, 12.8 kHz,

16.0 kHz, 21.3 kHz, 25.6 kHz, 32.0 kHz, 42.7 kHz, 48 kHz

256 phrases

• Maximum number of phrases:

• Sound volume adjustment function built in (4 sounds independently adjustable in 29 steps)

• External voice data can be input

• 14-bit D/A converter built in

• Built-in low-pass filter:

• Package:

Digital filter
