Serial Register Interface ADPCM CODEC for Telephone Recording

GENERAL DESCRIPTION

The MSM7708-02 is a CMOS IC developed for applying to PHS (Personal Handyphone System).

This device provides a CODEC function which performs transcoding between the voice band

analog signal and 32 kbps ADPCM data. It also provides a serial register interface function for

telephone call recording.

Provided with such functions as DTMF tone and several kinds of tone generation, transmit/

receive data mute and gain control, side-tone pass, and voice/silence detection, the MSM7708-

02 is best suited for PHS handsets.

FEATURES

• Single 3 V power supply operation (V : 2.7 V to 3.6 V)

• Low power consumption

When system is operating: 6 mA typ.

When powered down: 0.02 mA typ.

(ADPCM CODEC)

• ADPCM: ITU-T Recommendations G.721 (32 kbps)

• Transmit/receive full duplex capability

• PCM interface code format: m-law or A-law selectable

• Serial ADPCM and PCM transmission rate: 64 kbps to 2,048 kbps

• Transmit/receive mute function; transmit/receive programmable gain setting

• Side tone generator (8-step level adjustment)

• Built-in DTMF tone, ringing tone, and various tone generators

• Built-in VOX function

(Serial Register Interface)

• Interface for a serial register: 1 Mb (MSM63V89C), 4 Mb (MSM6684), 8 Mb (MSM6685)

• Interface for a serial voice ROM: 1 Mb (MSM6595A), 2 Mb (MSM6596A), 3 Mb (MSM6597A)

• Maximum recording time: 32 s (1 Mb), 128 s (4 Mb), 256 s (8 Mb)

• Maximum recording channels: 32 ch

• Playback data transmit/receive selectable

• Package:

64-pin plastic TQFP (TQFP64-P-1010-0.50-K) (Product name : MSM7708-02TS-K)
