Product Summary

The CXD9841-M is a Single-Chip FaxEngine. It consists of the Single-Chip FaxEngine that contains an embedded modem Digital Signal Processor (DSP), and a separate Integrated Analog (IA) device (20415). The CXD9841-M, along with the supporting firmware and evaluation system, comprises a complete facsimile machine—needing only power supply, scanner, and printer mechanism components to complete the machine.
