ADI Does WiMax
Unlike conventional solutions that implement the analog functions on separate devices or include the data converters on the ASIC, the AD9352 and AD9353 RF transceivers utilize "smart-partitioning," a concept pioneered by ADI, to integrate all the analog signal processing technology--analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF functions--on a single chip. This allows the digital baseband chips to be manufactured on more cost-effective fine line processes, such as 90 nm or 65 nm. The transceivers feature a direct connection to the digital modem via the ADI/Q(TM) digital I/Q interface, a simple parallel CMOS digital I/O interface that has been adopted by multiple digital modem partners.
"ADI is the first company to introduce RF CMOS direct conversion WiMAX transceivers that combine high integration with high performance, and offer the ADI/Q digital I/Q interface for a seamless connection to the digital baseband," said Bernard Aboussouan, VP, marketing and business development for Sequans Communications, a leading supplier of fixed and mobile WiMAX silicon and software. "We chose to partner with ADI and implement the ADI/Q digital interface on our SQN1110 802.16e compliant digital baseband. We are confident that ADI's WiMAX transceivers combined with our digital baseband will offer a solution that meets the price, performance and time-to-market requirements of WiMAX terminal manufacturers."
