ADC12QJ800AAVT

Analog To Digital Converters (ADC) Overview

The ADC12QJ800AAVT is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments operating at a maximum sampling rate of 800 MSPS. It features a non-interleaved architecture with an internal dither function to reduce high-order harmonics. The device provides a full-scale input voltage of 800mVPP-DIFF and a full-power bandwidth of 6 GHz. Performance specifications include a signal-to-noise ratio (SNR) of 57.6 dBFS and an effective number of bits (ENOB) of 9 bits at 97 MHz. It utilizes a JESD204C serial interface supporting up to 8 SerDes lanes with baud rates up to 17.16 Gbps. Power consumption is 415 mW per channel at 800 MSPS, supplied by 1.1 V and 1.9 V rails.

Analog To Digital Converters (ADC) Feature Summary

• Non-interleaved architecture with internal dither for harmonic reduction
• JESD204C interface supporting 64B/66B and 8B/10B encoding modes
• Integrated PLL with VCO for optional internal clock generation
• Timestamp input/output capability for pulsed system synchronization

Analog To Digital Converters (ADC) Applications

• Light detection and ranging (LiDAR)
• Multi-channel oscilloscopes and digitizers
• Wireless communications test equipment
• Electronic warfare (SIGINT, ELINT)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'AAVT' against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with JESD204C receivers in the target design. Confirm that the FCBGA-144 package dimensions align with the PCB layout requirements. Check for any export control restrictions associated with this component before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC12QJ800AAVT when four independent channels are required for high-speed data acquisition. This model is suitable for applications needing direct RF sampling of L-band and S-band signals. Consider the power budget carefully, as each channel consumes significant power at maximum sampling rates. Ensure the system can support the necessary clocking infrastructure or utilize the internal PLL if external clocking is constrained.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12xJ800 family, which includes dual and single-channel variants. All members share the same 12-bit resolution and 800 MSPS sampling speed but differ in channel count and pin configurations. The quad-channel version integrates all four converters into a single FCBGA-144 package, optimizing board space for multi-channel systems compared to using multiple single-channel devices.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12DJ800AAVT serves as a dual-channel alternative within the same family. The ADC12SJ800AAVT is the single-channel equivalent. These parts share identical electrical performance per channel but offer different I/O counts and lane configurations.
