SAN JOSE, Calif. -- Toshiba America Electronic Components Inc. has announced a two-chip set for the IEEE 802.11a wireless LAN standard, with specific intent of addressing an audio-visual distribution application in the home. The chipset comprises a baseband IC and an intermediate frequency (IF) chip.
"Toshiba Corporation developed a 5-GHz WLAN solution to address the emerging market of wireless audio and video distribution in the home of the future," said Farhad Mafie, vice president of the ASSP business unit at TAEC. "We believe the 5GHz WLAN is an ideal wireless technology and will become one of the key standards for wirelessly dispersing A/V between residential gateway products and other WLAN-enabled products at home."
The baseband chip, designated TC35672, can process data transferred at 54-Mbits per second, and has 10-bit analog-to-digital and digital-to-analog converters that operate at 40-MHz, the company said. The device is based on Toshiba's proprietary TX39 core and power management system.
The IF chip, designated TA35151, integrates an orthogonal modulator and demodulator with a direct current (DC) offset function that removes any dc offset.
Toshiba said it is also developing an RF IC that would include a mixer, low noise amplifier and phase-locked loop (PLL), power amplifier and switch. This next generation chipset will offer both 5-GHz and 2.4-GHz operation, in full compliance with the IEEE 802.11a and IEEE 802.11b standards, respectively.
Samples of TC35672 and TA35151 are scheduled to be available in November 2002 at $65.00 the pair in 100-piece quantities. Mass production is slated to begin in March 2003 and is expected to rise to 100,000 units of each a month in 2003, the company said.
