Samsung Adopts Silicon Laboratories' Highly Integrated Fax Modem Solution

January 08, 2007
Fax ISOmodem® is Easy-to-Use and Globally Compliant for Multifunction Printers and Fax Machines®

The fax ISOmodems are full-featured, integrated modems complete with an easy-to-use UART interface, integrated ROM and RAM, and a digital signal processor (DSP). Unlike legacy controllerless modems, fax ISOmodem chipsets include an internal modem controller. Standard Class 1 AT commands control modem operation to minimize processor overhead and software complexity, and make the driver software more portable between systems. This simplifies system design, reduces development effort and speeds time-to-market. The Si2435 supports fax rates up to 33.6 kbps and includes voice processing capabilities and a direct interface to an optional Silicon Laboratories Si3000 voice codec, providing telephone functionality to systems with a handset.

"In order to meet customer demand for a high-performance and economical multi-function printer, we needed an easy-to-use fax modem that would be globally-compliant, compact and cost effective," said Kwang-young Chung, vice president of the Printer R&D team of Samsung Electronics. "Silicon Laboratories' fax ISOmodem solution meets these goals, enabling us to deliver a multi-function printer with substantially improved performance."

Compliant with FCC, JATE, EU and numerous other PTT standards, Silicon Laboratories' Si2435 enables global compliance and interoperability. A single product SKU can ship worldwide. With more than 100 issued or pending patents related to this technology, Silicon Laboratories' modem solutions are field proven.

"Through our relationship with Samsung, we are extending our market leading modem technology into the established fax market," said Dave Bresemann, vice president of Silicon Laboratories. "By offering a controller-based, globally-compliant fax modem that is easier to use and more compact than legacy solutions, we are eliminating many of the design headaches associated with integrating fax modems into multi-function printers and other equipment."
