Product Description
The SMD24XX MODEM MODULE is a complete modem
module that meets global telephone line requirements. Available
in a socket (64,5 mm x 26,5mm) size footprint, the device is ideal
for embedded modem applications due to its small board space, low
power consumption and global compliance. The device is available
in 5 different versions, ranging from V.92 down to V.22bis. The
module allows you to reduce time to market by using a ready to use
approved solution. |

Evalution Kit
A modem "motherboard" is available which
allows easy evaluation of the SMD24XX modem module. This board allows
the customer to connect the module to a PC via a standard DB-9 connector
and to the PSTN via a standard RJ11 modular connector. The motherboard
fits in a standard ABS housing. |
