Conexant’s SCE400 FaxEngine product family features the CX95410
document imaging System-on-Chip (SoC) based on Conexant’s Configurable
System Solution (CSS) architecture, which allows manufacturers to use a
single device across multiple product platforms, providing them with design
flexibility and cost-savings. The SCE400 provides manufacturers with the
core hardware and software required to develop a complete fax machine.
It also includes Conexant’s SoftFax technology and innovative SmartDAA®
technology, which eliminates the need for costly line transformers, relays,
and opto-isolators that are typically used in discrete DAA implementations.
