IDT Announces Industry's First Low-power Dual 16-bit DAC with JESD204B for Multi-carrier Broadband Wireless Applications

Integrated Device Technology (News - Alert), Inc. (IDT^®) (NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the industry's first low-power dual 16-bit digital-to-analog converter (DAC) with JESD204B for multi-carrier broadband wireless applications. IDT's high-speed DAC delivers best-in-class dynamic performance, eases system-level cooling requirements, and simplifies board routing with the JESD204B digital serial interface.

The DAC165xD1G5HN is a 16-bit 1.5 Gsps dual DAC with 10 Gbps JESD204B serial interface and x2, x4, and x8 interpolation filters. It is optimized to cover all major multi-carrier broadband wireless customer platform requirements and derivatives. Consuming only 400 mW of power per channel at full operating speed, the IDT data converter dissipates less heat than competitive offerings in its class, allowing for more densely populated enclosures and reduced system-level cooling requirements. Furthermore, the performance of the JESD204B interface greatly simplifies PCB routing and stack-up by replacing 32 matched differential lane pairs (common with traditional interfaces) with only four JESD204B high-speed differential lanes. The DAC165xD1G5HN is ideal for use in wireless infrastructure radio base station transceivers, such as long-term evolution (LTE (News - Alert)), long-term evolution advanced (LTE-A), long-term evolution time-division duplex (LTE-TDD), multi-carrier global system for mobile communications (MC-GSM), and wideband code division multiple access (W-CDMA).

"Our new DAC products expand IDT's leading high-performance, low-power wireless communications portfolio," said Christian Kermarrec, vice president and general manager of Wireless Systems at IDT. "As the industry's lowest-power 1.5 Gsps dual DACs to include the JESD204B high-speed serial interface, the DAC165xD1G5HN family of converters offers our customers tremendous value in performance, ease-of-use, and thermal management. In addition, the ability to use these converters across various BTS platforms makes them highly versatile and attractive to customers who are being driven to reduce the number of vendors used and, as a result, are turning to trusted experts such as IDT. These products join our RF, data compression, RapidIO^®, and timing solutions to provide a comprehensive system-solution."

"There is strong industry demand for the JEDEC interface, as it enables customers to achieve higher system integration, lower board cost and complexity, and overall system performance gains to keep pace with an insatiable demand for more bandwidth," said Sunil Kar, senior director in the Xilinx (News - Alert) Wireless Business Group. "Today's wide-bandwidth wireless infrastructure applications use multiple high-sample-rate data converters that require the JESD204B serial interface. Xilinx's support of these data converters is accelerating the adoption of the JESD204B standard and providing customers with powerful solutions for next-generation communications equipment."

IDT's JESD204B-enabled DACs feature harmonic clocking and deterministic latency to support beam-forming via multi-device-synchronization (MDS), enabling multiple DAC output streams to be sample-level synchronized and phase-coherent for coordination at the system level. Additional applications include communication systems based on LMDS/MMDS, point-to-point microwave backhaul, direct digital synthesis (DDS) instruments, high-definition video broadcast production equipment, and automated test equipment (ATE).

Pricing and Availability

The IDT DAC1658D1G5HN and DAC1653D1G5HN are currently sampling to qualified customers and are available in an 8 mm x 8 mm 56-pin HVQFN package. The DAC1658 is a high-output common mode version (2.8 to 3.0 V), and the DAC1653 is a low-output common mode version (0.25 to 0.5 V).
