Single Rail CODEC

GENERAL DESCRIPTION

The MSM7507 is a single-channel CODEC CMOS IC 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 device is

optimized for ISDN terminals, digital wireless systems, and digital PBX systems.

The device uses the same transmission clocks as those used in the MSM7508B and MSM7509B.

The analog output signal, which is of a differential type and can drive a 600 W load, can directly

drive a handset receiver.

FEATURES

• Single power supply: +5 V ±5%

• Low power consumption

Operating mode:

Power down mode:

• ITU-T Companding law

20 mW Typ. 40 mW Max.

0.03 mW Typ. 0.3 mW Max.

= 5 V

MSM7507-01: m/A-law pin selectable

MSM7507-02: m-law

MSM7507-03: A-law

• Transmission characteristics conforms to ITU-T G.714

• Built-in PLL eliminates a master clock

• Serial data rate: 64/128/256/512/1024/2048 kHz

96/192/384/768/1536/1544/200 kHz

• Adjustable transmit gain

• Adjustable receive gain

• Built-in reference voltage supply

• Analog output can directly drive a 600 W line transformer

• The 24-Pin SOP package products provide pin compatibility with the MSM7543/7544

• The 20-Pin SSOP package products have 1/3 the foot print of conventional products

• Package options:
