AMC2901XL, AMC224XL and AMC2348XL V.22bis Low Speed Embedded Modem Modules

The Alpha Micro AMC224XL and AMC2348XL are feature enhanced V.22bis data modem modules, each designed onto our standard modem footprint.

Featuring line data rates of up to 2400bps these modems are ideally suited to a range of applications where relatively small amounts of data need to be transferred over a telephone line.

Fast connection algorithms make the modems ideally suited for use in point of sale or banking environments where small data payload and short call duration is important. Using our standard modem footprint offers the flexibility and speed of upgrading to a faster module with minimum design effort.
