ADC12DJ3200ZEGT

Analog To Digital Converters (ADC) Overview

The ADC12DJ3200ZEGT is a radiation-hardness-assured (RHA), QMLV-qualified, dual-channel RF-sampling analog-to-digital converter manufactured by Texas Instruments. It supports a sampling rate of up to 3.2 GSPS per channel in dual-channel mode or 6.4 GSPS in single-channel mode with 12-bit resolution. The device features an 8.0 GHz full-power input bandwidth and utilizes a JESD204B interface with up to 16 serial lanes supporting rates up to 12.8 Gbps. Designed for high-reliability environments, it includes digital downconverters (DDC) and advanced synchronization capabilities such as SYSREF windowing and no-noise aperture delay adjustment.

Analog To Digital Converters (ADC) Feature Summary

• Radiation-hardness-assured (RHA) and QMLV qualification for 300-krad tolerance
• Dual-channel architecture allowing flexible trade-off between channel count and instantaneous bandwidth
• JESD204B interface with Subclass 1 compliance for deterministic latency and multi-device synchronization
• Integrated digital downconverter (DDC) for real and complex output decimation

Analog To Digital Converters (ADC) Applications

• Frequency-agile radar systems requiring direct RF sampling
• Electronic warfare and signal intelligence applications
• Software-defined radio (SDR) infrastructure
• High-performance test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ZEGT against official Texas Instruments documentation to confirm package type and tape-and-reel configuration. Ensure procurement channels are authorized distributors capable of handling QMLV/RHA qualified components. Confirm that the supply chain maintains the required environmental controls for radiation-hardened devices.

Analog To Digital Converters (ADC) Selection Notes

Select this component when radiation hardness and military-grade reliability are mandatory requirements. Compare performance metrics such as SFDR and noise floor against standard commercial variants if radiation tolerance is not needed. Verify that the system clocking architecture supports the required JESD204B lane rates and SYSREF distribution for multi-device synchronization.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12DJ3200QML family, which is specifically designed for defense and aerospace applications. It shares core architectural similarities with the commercial ADC12DJ3200 but undergoes rigorous screening and testing to meet QMLV standards. The ZEGT suffix indicates a specific packaging and reel configuration distinct from other variants like the ZMX.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must also be QMLV/RHA qualified. Consider the ADC12DJ3200ZMX/EM for identical functionality with different packaging. Commercial equivalents like the standard ADC12DJ3200 lack radiation hardness and should only be considered if the application environment permits.
