TDK Semiconductor Unveils Low Cost Soft Modem Front-End For Speeds to 56Kbps

12/5/2002 - TDK Semiconductor Corp., a specialist in the field of mixed-signal and analog communication semiconductors, unveiled the first member of a family of soft modem Analog Front End (AFE) devices. The company's new 73M1901 includes a 16-bit CODEC and a fully differential hybrid circuit, and supports low-speed (V.22bis) and high-speed transmission up to 56Kbps (V.92).

The 73M1901 allows designers to lower total system cost in satellite set-top boxes, PCs, game consoles and other consumer appliances requiring network access. "As processors become more powerful, more applications will migrate to soft modems," said Kourosh Boutorabi, TDK's product line manager for embedded modems. "The 73M1901 AFE makes the construction of a soft modem very easy and very inexpensive."

Building on TDK's well-known K-Series and 73M2901 series of single-chip modems, the 73M1901 supports on-chip transformer DAA line sensing and control, loop back and two power-conserving operating modes. The 73M1901 facilitates integration with popular processors and high-speed modem data pumps and can be configured for CTR-21, FCC and other Telco standards worldwide.

The new 73M1901 device is now available for sampling in a 32-pin TQFP package, and will be priced at under $3 in 1,000-unit lots.
