3/19/2003 - TDK Semiconductor Corporation, a leader in mixed-signal and analog communication semiconductors, has unveiled a new addition to its family of embedded modem Analog Front End (AFE) devices. The new 73M1903 eliminates the need for a dedicated crystal oscillator, features programmable sample rates, and is the lowest cost solution on the market for analog modems up to 56kbps.
The 73M1903 is ideal for DSP or RISC based soft modem applications such as multi-function printers/fax machines, game consoles, internet appliances and set-top boxes, and offers a complete array of features designed to reduce the external component count.
"A distinctive feature of the device is DAA and pin compatibility with TDK's flagship V.22bis hard modem, the 73M2901CL. It also has the ability to support third party high speed data pumps on the same PCB, " said Kourosh Boutorabi, product line manager for embedded modems. "This offers customers the ability to economically configure low and high speed modem solutions in the same product as well as a risk-free migration path from hard to soft modems."
Building on TDK's highly successful K-series and 73M2901 series of modems, the 73M1903 includes on-chip PLL supporting reference frequencies between 9 and 40MHz, power conservation modes, sigma-delta converter with programmable sample rates, differential hybrid circuitry, and can be configured for CTR-21, FCC and other telco standards worldwide. The 73M1903 is now available for sampling in low cost 20-pin SOIC and 32-pin TQFP packages and will be priced at under $3.00 in 1,000 unit lots.
More than 60 million TDK modems have shipped worldwide for applications including set-top boxes, point-of-sale terminals, payphones, industrial and security monitoring systems.
