LINEAR CODEC FOR DIGITAL CELLULAR TELEPHONE
The
碌
PD9930 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.
