Single Chip MSK Modem with Compandor for Cordless Telephone

GENERAL DESCRIPTION

The MSM7532 is a baseband device with a modem function and a baseband voice signal processing

functionforanalogcordlesstelephone. ThevoicesignaltransmitterinthisICconsistsofahigh-pass

filter, compressor, scrambler, pre-emphasis, limiter, and splatter filter.

The voice signal receiver consists of a bandpass filter, a de-scrambler , a de-emphasis, an expander,

an electronic volume, and a ceramic receiver driving circuit.

The MODEM in this IC transmits and receives MSK (Minimum Shift Keying) modem signals.

FEATURES

• Built-in ceramic receiver drive amplifiers

• The compander input reference level, limiter level, and modem transmit level are easy to be

externally adjusted.

• Built-in 2-bit electronic volume

• A microphone amplifier and an amplifier available for users are built in.

• Mode settings using parallel interfaces

• Built-in compander dynamic range: 70 dB

• Built-in maximum gain limit circuit for expander

• The bit rate of MSK modem is switchable between 2400 bps and 1200 bps.

• Scrambler and emphasis can be used by serially connecting them or can be used separately with

each other.

• Three kinds of the reverse frequency of the scrambler are selectable.

• Themodemreceiverfunctionsdetectbitsynchronoussignalsandframesynchronoussignals.

• Four-step power down modes

• Built-in crystal oscillation circuit

• Wide range of power supply (1.8 V to 5.5 V)

• Package:

56-pin plastic QFP (QFP56-P-910-0.65-2K) (Product name : MSM7532GS-2K)
