General Description

The Z02215 is a synchronous single-chip V.22bis modem capable of 2400 bps full-duplex over dial-up lines. It is a full-featured, self-controlled modem that includes a modem controller, DSP, and Analog Front End (AFE) functions. This device is specifically designed for use in embedded modem applications where space, performance, and low-power consumption are key requirements.

Operating over the Public Switched Telephone Network (PSTN), the Z02215 meets the modem standards for V.22bis, V.22, V.23 (Minitel), V.21, Bell 212A, Bell 202, Bell 202T, and Bell 103.

A typical modem can be created by simply adding a phone- line interface (DAA), and DTE interface.

All modulation, demodulation, filtering, Analog to Digital (A/D), and Digital to Analog (D/A) conversion functions for transmission and reception are provided onchip. Automatic compromise equalizers are included to optimize performance over a wide range of line types.
