GENERAL DESCRIPTION
The Z02205 V.22bis Modem Controller serves as the modem controller in embedded V.22bis modem applications. A complete modem can be made by adding ZiLOG data pump (Z02201), phone line interface, and the required DTE interface. The Z02205 has been designed for low-cost use and includes a glueless interface to the ZiLOG data pumps. The Z02205 is ideal for applications where small size and low power consumption are requirements.
