AD9689BBPZ-2600

Overview

The AD9689BBPZ-2600 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at sampling rates up to 2.6 GSPS. It features a multistage differential pipelined architecture with integrated output error correction logic and on-chip buffers. The device supports direct RF sampling of signals up to 5 GHz, utilizing a 9 GHz analog input bandwidth. Key specifications include a typical SNR of 53 dBFS at 5.53 GHz and an SFDR of 59 dBFS under the same conditions. Power consumption reaches 3.1 W in default mode without DDCs. It operates within a temperature range of -40°C to +85°C and is housed in a 196-ball BGA package.

Feature Summary

• Integrates four digital downconverters (DDCs) with 48-bit numerically controlled oscillators (NCOs) and programmable decimation filters for multiband receiver applications.
• Supports flexible JESD204B Subclass 1 high-speed serialized outputs configurable across one-lane to eight-lane setups based on lane rate requirements.
• Includes programmable threshold detectors and signal monitoring blocks to facilitate automatic gain control (AGC) by detecting overrange conditions with low latency.

Applications

• Diversity multiband and multimode digital receivers
• Phased array radar and electronic warfare systems
• Electronic test and measurement equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official channels. Confirm that the specific suffix indicates the 2.6 GSPS variant. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate supply chain documentation against current manufacturer records prior to integration.

Selection Notes

Select this model when system requirements demand high linearity and wide bandwidth for direct RF sampling applications. Consider the power dissipation characteristics and thermal management needs associated with the 196-ball BGA package. Evaluate the necessity of internal DDCs versus external processing to optimize system complexity and performance metrics.

Part Context

This component belongs to the AD9689 family of high-performance data converters. It shares pinout and memory map compatibility with the AD9208, facilitating potential design transitions. The device represents a solution for broadband communication infrastructure requiring precise digitization of high-frequency signals.

Replacement Considerations

The AD9208 offers functional compatibility regarding pinout and memory mapping but operates at a different sampling rate. Verify interface timing and power supply requirements when substituting components to ensure system stability.
