OCM-22 One-Chip Modem for Embedded Applications
Features
■
Introduction
OCM-22 is a low-cost modem solution for low-speed embedded applications. OCM22 includes a simplified AT command set and supports data rates from 300 bits/s (V.21) to 2400 bits/s (V.22bis) and only requires a CSP1034 or CSP1035A to make a complete modem. OCM-22 provides a choice of two system interfaces, a serial interface or an 8-bit parallel interface. The serial interface can be used in systems that have an available serial port. In other systems, the parallel interface can be I/O or memory mapped onto typical processor buses. In typical applications, OCM-22 is paired with Agere's CSP1035A silicon DAA to implement a low-cost worldwide modem.
