V.90 embedded modem chipset cuts power
and space
Texas Instruments and PCTEL reckon they have introduced the lowest power and smallest V.90 embedded modem chipset.
Texas Instruments and PCTEL reckon they have introduced the lowest power and smallest V.90 embedded modem chipset for integration into end-equipments with very small form factors at low cost This new two-chip solution is said to cut power consumption by as much as 90% and board space by up to 40% compared with existing solutions, enabling a new class of Internet access devices with smaller power and space requirements

Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The offering combines TI's expertise in digital signal processing with PCTEL communications software.
This new two-chip solution, which consists of a power-efficient TMS320C54V90 DSP and PCTEL line-powered data access arrangement (DAA), consumes only 25mW when running a V.90 modem, and requires as little as 645mm2 of board space.
The C54V90 DSP incorporates PCTEL's modem control and data pump software, eliminating the need for off-chip memory, and integrates the digital portion of the DAA on-chip, thereby decreasing the conventional embedded modem solution from five or six chips to just two chips.
The PCTEL line-powered DAA is used to interface to the telephone line and is compatible with local phone access in more than 65 countries.
TI chose PCTEL communications software because of its proven performance in millions of Internet-enabled products throughout the world.
PCTEL provides modem solutions to nearly all of the world's motherboard manufacturers and was a leading modem provider in 2000.
TI and PCTEL also plan to release a V.92 embedded modem chipset that will offer more symmetric data transmission speeds with higher upload bandwidth, faster handshaking time to achieve modem connection and a modem on hold feature that allows the modem connection to be sustained when a phone call occurs on the same line.
All 17 C5000 DSPs are code-compatible and offer industry-leading performance, small code size and the industry's lowest power consumption.
TI DSPs are supported by eXpressDSP Real-Time Software Technology, which includes the DSP/BIOS real-time kernel, the TMS320 DSP Algorithm Standard, the Code Composer Studio IDE and interoperable software from the industry's largest third-party network.
Samples of the C54V90 chipset are available today, with production scheduled to begin in 4Q01.
Datasheets and product briefs describing the C54V90, as well as a development kit, are also available from TI.
