ADI continues to push the boundary of analog front end chips in def/aero
Analog Devices (ADI) unveiled a new 14-bit, 2.6 GSPS dual A/D converter AD9689 for IF/RF sampling, where the ADC consumes power of 1.55 W per channel, nearly half less than some of the similar ADCs in the advanced instrumentation and defence market.
ADI also introduced two related converters: the AD9695, a dual 14-bit 1300/625 MSPS device, and the AD9697, a single 14-bit, 1300-MSPS unit. Both are lower-power, pin-compatible upgrades for existing devices. All three A/D converters include JESD204B interfaces for efficient and highest-speed interconnection to FPGAs, and share the same register map, so they can be used across multiple platforms with minimal coding efforts. Since many system architectures require complementary signal-transmission channels, Analog Devices also offers the AD9172 and AD9162 DACs as counterparts to the AD9689 and AD9695.
AD9689 features full-speed spur free dynamic range (SFDR) of 64 dB full scale for a 3-GHz analog input. Other features of this converter include user-programmable FIR filters which allow users to perform quadratic error correction and equalization for optimized performance, and an analog input bandwidth of 9 GHz in the BGA-packaged version to allow for RF sampling up to and beyond the 4th Nyquist zone. The AD9689 A/D converter's JESD204B interface supports 16 GBPS/lane performance, which exceeds the 12.5 GBPS/lane requirement of the standard. Thus, the system FPGA can use fewer lanes, while freeing resources for other functions, suggests ADI.

In another announcement related to def/aero, ADI and API Technologies to collaborate on the production of custom, high reliability electronic modules and assemblies using API’s U.K.-based facilities. API said in its release "This alliance is designed to permit ADI’s wide range of high performance integrated circuit (IC) and high speed digital signal processing technology to integrate with API’s value-added engineering services, footprint reduction and miniaturization technologies, and in-house production, manufacturing and testing capabilities to allow API to deliver a U.K.-designed and manufactured, integrated high performance solution directly to U.K. and European customers to support their custom aerospace and defence, mission critical requirements."
API and ADI sales forces plan to cooperatively identify and direct to API those U.K. and European aerospace and defense customers who are seeking a solution that integrates ADI’s proprietary semiconductor and IC technologies within a custom-designed API module.
“We are very excited about our growing relationship with ADI, which has been important in Europe to both companies for more than 15 years,” said Richard Farrington, Managing Director and Vice President, API Technologies U.K. “Through this alliance, both ADI and API will better serve our European customers through a comprehensive forward-looking portfolio of U.K.-designed, industry-leading solutions for the global high reliability electronics market.”
“Our expanded collaboration with API strengthens our commitment to our European customers for the highest quality Analog Devices solutions for innovative assemblies and integrated circuits, now delivered from Europe through API’s U.K.-based engineering, design and manufacturing operations,” said Bryan Goldstein, General Manager, Aerospace and Defense Business Unit, Analog Devices.
