... DESCRIPTION The 73M2901CE low speed modem integrates a data pump, controller, and analog front end in a 3.3V device with a powerful "AT" command host interface. The modem reduces external component count/cost by incorporating many features like parallel phone detect, Line-In-Use and Ring detection in software without additional components required. The device is a " ...
