DESCRIPTION
The M5913 is fully integrated PCM (pulse code
modulation) codecs and transmit/receive filter us-
ing CMOS silicon gate technology.
The primary applications for the M5913 are tele-
phone systems :
- Switching - M5913-Digital PBX’s and Central
BLOCK DIAGRAM
DIP 20
ORDERING NUMBER: M5913B1
Office Switching Systems
- Concentration - M5913 Subscriber Carrier and
Concentrators.
The wide dynamic range (78dB) and the minimal
conversion time make it ideal products for other
applications such as:
- Voice Store and Forward
- Secure Communications Systems
- Digital Echo Cancellers
- Satellite Earth Stations.
