DTMF GENERATORS
DESCRIPTION
The SC9200A/B tone generators are designed for
μ
C interfaces.
They can be instructed by a
μ
C to generate 16 dual tones and 8
single tones from the DTMF pin. The SC9200A provides a serial
mode whereas the SC9200B contains a selectable serial/parallel
mode interface for various applications such as security systems,
home
automation,
remote
control
through
telephone
lines
communication system, etc.
FEATURES
* Operating voltage: 2.0V~5.5V
* Serial mode for the SC9200A
* Serial/parallel mode for the SC9200B
* Low standby current
* Low total harmonic distortion
* 3.58MHz crystal or ceramic resonator
