ML7041

The ML7041 is a single channel,low-voltage linear Codec targeting the digital handset market including CDMA and TDMA applications.The ML7041 sets a new standard for functionality by incorporating all major peripheral handset features, including speaker driver,tone generator, and voice detection circuits. The ML7041, a third generation Oki linear Codec, offers an improved feature set by incorporating a robust amplifier circuit capability on-chip to drive the latest cutting-edge, low-impedance dynamic speakers commonly used in handsets.

MSM7732-01

The MSM7732 is a single-channel full duplex CODEC CMOS IC which performs mutual transcoding between the analog voice band signals and 64 kbps PCM serial data. This device performs such functions as DTMF tone and several types of tone generation, transmit/receive data mute and gain control, and side tone path.

MSM7716

The MSM7716 is a single-channel, CODEC CMOS IC for voice signals that contains filters for linear A/D and D/A conversion.

MSM7705-01/02/03

The MSM7705-01/02/03 are four-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz. These devices contain filters for A/D and D/A conversion.

ML7000-01/ML7001

The ML7000/ML7001 are single-channel CMOS CODEC LSI devices for voice signals ranging from 300 to 3400 Hz with filters for A/D and D/A conversion. Designed especially for a single-power supply and low-power applications, the devices are optimized for ISDN terminals, digital wireless systems, and digital PBXs. The devices use the same transmission clocks as those used in the MSM7507.

ML7033

The ML7033 is a 2-channel Line Card CODEC CMOS IC for voice signals ranging from 300 to 3400 Hz. This device contains 2-channel analog-to-digital (A/D) and digital-to-analog (D/A) converters on a single chip. The ML7033 is designed especially for a single power supply and low power applications and achieves a reduced footprint. The ML7033 is best suited for line card applications with easy interface to subscriber line interface circuits (SLICs). Especially Intersil HC5518x series.

ML7022-01

The ML7022 is a single-rail two-channel DSP CODEC IC for voice telecom line card applications. This device incorporates dual 3-bit latches to directly control the modes of operation (Borscht functions) of a complimentary SLIC. This functionality simplifies the design process, and provides a seamless interface with popular SLICs such as Ericsson's PBL38630/40 and Intersil's UniSLIC14.

MSM7540/7560

The MSM7540/7560 are single channel ADPCM CODEC ICs which perform mutual transcoding between an analog voice band signal 300 to 3400 Hz and 32 kbps ADPCM serial data. Using advanced circuit technology, these devices operate using a single 5 V power supply and have low power consumption. The MSM7540/7560 are optimized for advanced digital cordless telephone system applications.

MSM7570/90

The MSM7570 and MSM7590 are single-rail, low-voltage, single-channel, full-duplex ADPCM CODECs which perform voice digitization using presampling and reconstruction filters for transmit and receive operations in systems upgrading to ADPCM (Adaptive Differential Pulse Coded Modulation) encoding techniques. These CODECs offer ADPCM encoder/decoder operation, reducing the data rate required to transmit a PCM encoded voice signal.

MSM7578H/7578V/7579

The MSM7578 and MSM7579 are single-channel CODEC CMOS ICs for voice signals ranging from 300 to 3400 Hz. These devices contain filters for A/D and D/A conversion.
