"Toshiba Corporation (Toshiba) developed a 5GHz WLAN solution to address the emerging market of wireless audio and video (A/V) 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."
"Our WLAN chipset was designed to maintain superior sensitivity and data throughput over the longest possible distance," said Andrew Burt, wireless market development director of the ASSP Business Unit at TAEC. "It supports high-speed processing and handling of analog and digital sources combined with low power operation for tomorrow's portable equipment," he added.
The baseband large scale integration (LSI), designated TC35672, integrates a dedicated circuit that can process data transferred at 54 megabytes per second, and 10-bit analog-to-digital and digital-to-analog converters that operate at 40 megahertz (MHz). High speed processing and low power consumption are supported by Toshiba's proprietary TX39 core and power management system.
The IF IC, designated TA35151, was designed expressly to interface with the baseband LSI. It integrates an orthogonal modulator and demodulator with a direct current (DC) offset function that removes the remaining DC elements in alternating current (AC). Upon receiving a signal from a radio frequency (RF) IC, it executes orthogonal modulation and demodulation and transmits the signal to the baseband LSI. It processes analog signals quickly, with high accuracy. In order to cover an optimized range of signals, both received and transmitted, it enables auto gain control of the amplifier to achieve reception exceeding 70 decibels (dB) and transmission of over 40dB.
The chipset supports the CardBus interface and allows integration of Personal Computer Memory Card International Association - (PCMCIA) based devices, such as peripheral component interconnect (PCI) cards, access points, personal computers (PCs) and personal digital assistants. The chipset's interoperability is assured with full conformity to the Wireless Fidelity (Wi-Fi) specification.
Toshiba is developing an RF IC that includes blocks for a mixer, low noise amplifier and phase-locked loop (PLL), power amplifier and switch. This next generation chipset will offer both 5GHz and 2.4GHz operation, in full compliance with the IEEE 802.11a and IEEE 802.11b standards, respectively. Smart antenna and security technologies, such as the Temporal Keying Integrity Protocol and the Advanced Encryption Standard, will be introduced in the next- generation chipset, thus achieving an ideal combination of highly secure wireless communication. The new chipset will also conform to the IEEE 802.1x authentication specification. The new chipset will be targeted at both Mini-PCI and PCMCIA-based applications.
