MSM7524

DTMF Transceiver

GENERAL DESCRIPTION

The MSM7524 is the single chip DTMF transceiver –generator/receiver– with the call progress

tone generator/detector and the special tone –1300 Hz in the first version, possible to be

modified– detector.

Each function block can be controlled by an external MCU via 4-bit processor interface.

The chip operates with +5 V single supply with low power consumption, and is suitable for

the telephone terminal equipment.

FEATURES

• Power supply voltage : +5 V ±10%

• Low power consumption

Operating mode : 8 mA Typ.

Power down mode : 10 mA Typ.

• 4-bit processor interface

• Dynamic range of DTMF receiver : 40 dB

• Low signal distortion output from DTMF generator

• Call progress tone detector : 330 to 640 Hz

• Call progress tone generator : 350/400/440/480 Hz

• Special tone detector: 1300 Hz ±20 Hz (for FAX)

• 3.58 MHz crystal oscillator circuit on chip

• Package :

32-pin plastic SSOP

(SSOP32-P-430-1.00–K) (Product name : MSM7524GS-K)
