ADC12QJ1600ALRSHP

Analog To Digital Converters (ADC) Overview

The ADC12QJ1600ALRSHP is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It supports a maximum sampling rate of 1.6 GSPS with a full-power input bandwidth of 6 GHz. The device features a JESD204C serial interface supporting up to 8 lanes with baud rates up to 17.16 Gbps. Key performance metrics include an SNR of 57.4 dBFS and an ENOB of 9.1 bits at 100 MHz. It operates on 1.1 V and 1.9 V supplies with power consumption of 1.9 W at 1 GSPS. Radiation tolerance includes 300 krad TID and SEL immunity up to 120 MeV-cm2/mg.

Analog To Digital Converters (ADC) Feature Summary

• Radiation-hardened design with high total ionizing dose tolerance and single-event latchup immunity for space applications.
• Integrated JESD204C interface supporting deterministic latency and multiple encoding modes for flexible system integration.
• Internal phase-locked loop with voltage-controlled oscillator enables standalone clock generation without external jitter cleaners.

Analog To Digital Converters (ADC) Applications

• Electronic warfare systems including signals intelligence (SIGINT) and electronic intelligence (ELINT).
• Satellite communications (SATCOM) requiring direct RF sampling of L-band and S-band frequencies.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix ALRSHP against the manufacturer's current datasheet to confirm package type and radiation qualification status. Ensure compliance with export control regulations as this component may require additional documentation for international shipping. Confirm that the procurement channel provides valid traceability for space-grade components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a quad-channel architecture is required for multi-signal acquisition in harsh radiation environments. The internal PLL simplifies clock tree design by reducing external component count. Verify that the 6 GHz input bandwidth aligns with the target RF sampling frequencies and that the JESD204C interface is compatible with the downstream FPGA or ASIC logic.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12QJ1600-SP family, which includes variants with different channel counts and interfaces. The -SP designation indicates a space-qualified version designed for reliability in orbital conditions. It shares core architectural similarities with commercial counterparts but undergoes stricter screening and testing protocols for radiation hardness assurance.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 1.6 GSPS sampling rate, 12-bit resolution, and JESD204C interface. Verify that any substitute offers equivalent radiation tolerance levels, specifically 300 krad TID and SEL immunity. Pin compatibility with the FCBGA-144 package should be confirmed before integration into existing PCB layouts.
