Analog Devices’ Next-Generation Advanced Instrumentation and Defense Applications Enabled

Analog Devices announced a 14-bit, 2.6 GSPS dual A/D converter which enables IF/RF sampling with superior speed and linearity. The AD9689A/D converter features power dissipation of 1.55 W per channel, half the dissipation of comparable solutions in the market, thus further increasing suitability for many of its targeted design situations.

In addition to the high-performance AD9689, ADI 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 D/A converters as counterparts to the AD9689 and AD9695.

Full-speed spur free dynamic range (SFDR) of the AD9689is an exceptional 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 JESD204 Binterface 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.
