Product details
Overview
ADC3223IRGZR from Texas Instruments is a dual-channel, 12-bit, 80–125 MSPS analog-to-digital converter optimized for high-input-frequency, wide-dynamic-range signal acquisition in RF receiver chains. It features serial LVDS output (two-wire or one-wire), internal PLL clock multiplication, SYSREF input for multi-chip synchronization, and operates from a single 1.8-V supply. It delivers 70.2 dBFS SNR and 87 dBc SFDR at fIN = 70 MHz, targeting radar and communications infrastructure.
For engineers reviewing the ADC3223IRGZR datasheet, ADC3223IRGZR pinout, ADC3223IRGZR application, or ADC3223IRGZR equivalent, this page provides verified specifications, validated VQFN-48 pin functions, real-world use cases in SDR and microwave receivers, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The ADC3223IRGZR integrates two independent 12-bit ADC cores sharing a common clock architecture with flexible divide-by-1/2/4 input clock buffer and an internal PLL that generates bit clock for LVDS serialization. Its dual-channel isolation exceeds 105 dB across 10–300 MHz, enabling simultaneous sampling without crosstalk in diversity or quadrature architectures.
It supports both dither and chopper modes to enhance AC performance and reduce harmonic distortion, and includes dedicated SYSREFP/SYSREFM inputs for JESD204B-compatible system-level timing alignment-though it uses SLVDS, not JESD204B. The device requires precise 1.8-V analog and digital supplies with separate AVDD/DVDD rails and decoupling per pin group.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, 12-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC3224IRGZR | Higher max sampling rate (125 MSPS vs. ADC3223's 125 MSPS upper limit; identical spec at 125 MSPS but ADC3224 rated up to 125 MSPS with tighter AC specs at 100+ MHz) | Preferred for systems requiring guaranteed 125 MSPS performance with margin at high input frequencies (>100 MHz) | Select ADC3224IRGZR when full 125 MSPS operation with best-in-class SFDR above 100 MHz is required; otherwise ADC3223IRGZR offers cost-optimized 80–125 MSPS coverage. |
| ADC32J23IRGZT | JESD204B serial interface (vs. SLVDS); same 12-bit resolution and 80–125 MSPS range; higher power (325 mW vs. 285 mW typical) | Better suited for high-density, FPGA-based systems with JESD204B PHY support and need for lane reduction beyond SLVDS | Choose ADC32J23IRGZT when migrating to JESD204B ecosystem or requiring deterministic latency with subclass 1 support; ADC3223IRGZR remains optimal for SLVDS-based legacy or cost-sensitive designs. |
Compared with ADC3224IRGZR and ADC32J23IRGZT, the ADC3223IRGZR provides the most cost-effective balance of SLVDS simplicity, 105 dB channel isolation, and verified 70.2 dBFS SNR at 70 MHz-making it ideal for radar front ends and SDRs where interface compatibility and thermal efficiency outweigh JESD204B feature requirements.

FAQ
What is the maximum sampling rate supported by the ADC3223IRGZR?
The ADC3223IRGZR supports a maximum sampling rate of 125 MSPS, with guaranteed AC performance (including 70.2 dBFS SNR and 87 dBc SFDR at fIN = 70 MHz) across its full 80–125 MSPS operational range. At 125 MSPS, it consumes 116 mW per channel and maintains 105 dB channel isolation up to 300 MHz.
Does the ADC3223IRGZR support JESD204B interface?
No, the ADC3223IRGZR does not support JESD204B. It uses a proprietary Serial LVDS (SLVDS) interface with two-wire or one-wire configurations. For JESD204B compatibility, consider the pin-compatible ADC32J23IRGZT, which shares the same 12-bit resolution and 80–125 MSPS range but implements JESD204B subclass 0/1.
How is multi-device synchronization achieved with the ADC3223IRGZR?
The ADC3223IRGZR achieves multi-device synchronization via dedicated differential SYSREFP and SYSREFM inputs. When driven synchronously with a system-wide SYSREF signal, these pins align internal sampling phases and frame boundaries across multiple ADC322x devices-enabling coherent sampling in beamforming and MIMO systems without external delay calibration.
What power supply requirements does the ADC3223IRGZR have?
The ADC3223IRGZR requires two separate 1.8-V supplies: AVDD (analog) and DVDD (digital), each specified from 1.7 V to 1.9 V. AVDD powers the analog core and clock circuitry; DVDD powers the digital interface and logic. Both require local decoupling-TI recommends 100-nF ceramic + 10-µF tantalum per supply pin group-and must be routed with low-inductance paths to the VQFN-48 thermal pad.
Is the ADC3223IRGZR pin-compatible with any higher-resolution alternatives?
Yes, the ADC3223IRGZR is pin-to-pin compatible with the 14-bit ADC3243IRGZR. Both share identical VQFN-48 packaging, pinout, power sequencing, register map, and SLVDS interface timing-allowing resolution upgrades without PCB redesign. Performance differences include higher SNR (73.5 dBFS) and SFDR (92 dBc) in the ADC3243IRGZR at equivalent sampling rates.
