ADC12DJ4000RFZEGT

Analog To Digital Converters (ADC) Overview

The ADC12DJ4000RFZEGT is a 12-bit RF-sampling analog-to-digital converter manufactured by Texas Instruments. It supports up to 8 GSPS in single-channel mode and 4 GSPS in dual-channel mode, enabling direct sampling of input frequencies from DC to above 10 GHz. The device features an analog input bandwidth of 8 GHz at –3dB and a full-scale input voltage of 0.8 VPP. It utilizes a JESD204C serial interface with a maximum lane rate of 17.16 Gbps, supporting both 8b/10b and 64b/66b encoding schemes. Power consumption is specified at 3.7 W, operating on 1.1 V and 1.9 V supplies.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix ZEGT against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required JESD204C receiver standards and power supply configurations before integration. Cross-reference the specific revision level to guarantee alignment with current design requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed direct RF sampling is required across multiple frequency bands. Evaluate the trade-off between line rate and lane count based on the available JESD204C lanes. Consider the inclusion of DDCs if baseband conversion and reduced interface rates are necessary for the target system architecture.
