4ch Single Rail CODEC

GENERAL DESCRIPTION

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.

Designed especially for a single-power supply and low-power applications, these devices

contain four-channel A/D and D/A converters in a single chip and achieve a reduced footprint

and a reduced number of external components.

TheMSM7705-01/02/03arebestsuitedfordigitaltelephoneterminals,digitalPABXs,andpush-

button phones.

• Conforms to ITU-T Companding law

MSM7705-01: m/A-law pin-selectable

MSM7705-02: m-law

MSM7705-03: A-law

• Built-in PLL eliminates a master clock

• The PCM interface can be switched between 4 channel serial/parallel

• Transmission clock: 64/128/256/512/1024/2048 kHz

96/192/384/768/1536/1544 kHz

(During 4 channel serial mode, the 64, 96, 128, and 192 kHz clocks are

disabled)

• Transmit gain adjustable for each channel

• Built-in reference voltage supply

• Analog output can directly drive a 600 W line transformer

• Package:
