LINEAR CODEC FOR DIGITAL CELLULAR TELEPHONE

The µPD9930 is a +3 V single power operation, low power consumption linear CODEC LSI developed for digital

cellular telephone use.

CODEC has a wide dynamic use.

This IC also features a microphone/receiver amplifier, a tone generator, DAI (Digital Audio Interface: conforming

to GSM11.10), and a power-saving function. These functions can be controlled by microcontroller.

In addition, 21 mW (TYP.) low power consumption is enabled during 3 V operation.

FEATURES

• +3 V single power supply

• Low power consumption

In operation: 7 mA (TYP.) (VDD = 3 V)

In stand-by mode: 50 µA (TYP.) (VDD = 3 V)

• CODEC

• 13-bit precision linear coding

• Transmission level can be controlled by microcontroller.

• Analog input/output funciton

• Low noise microphone amplifier

• High output receiver amplifier

Piezo-electric receiver can be directly driven.

Gain canbe controlled by microcontroller.

• On-chip amplifier for accessory input/output

• Tone generator

• Frequency, generating pattern and gain can be controlled

by microcontroller.

• DTMF generation function

• Various service tone generation function

• GSM triple tone generation function

• Desired tone frequency can be registered (0.3 to 3.4 kHz)

• DAI

• Conforming to GSM11.10

• Test mode can be set by terminal or microcontroller

command.

• Stand-by mode

• Rise time at time of stand-by clearing: 30.5 ms (TYP.)

• Master clock generation PLL (external clock input: 8 kHz)

• Tone interrupt pattern output function

• Ringer output function
