ADC32RF54IRTDT

Analog To Digital Converters (ADC) Overview

The ADC32RF54IRTDT is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It features a single-core non-interleaved architecture with a sampling rate of 2.6 GSPS and supports RF input frequencies up to 3 GHz. The device delivers a noise spectral density of -155.6 dBFS/Hz without averaging, improving to -160.4 dBFS/Hz with 4x internal averaging. It includes four digital down-converters (DDC) per channel with 48-bit NCOs for phase-coherent frequency hopping in under 1 µs. Data output utilizes a JESD204B serial interface supporting lane rates up to 13 Gbps with subclass 1 deterministic latency. Power consumption is 2.6 W per channel at 2x averaging. It operates on 1.8 V and 1.2 V supplies within an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Single-core non-interleaved architecture minimizes interleaving spurs and maximizes signal-to-noise ratio.
• Integrated quad-band digital down-converters enable complex output decimation and fast phase-coherent frequency hopping.
• JESD204B serial data interface provides high-speed connectivity with deterministic latency support.
• On-chip signal averaging capabilities significantly reduce noise spectral density for improved dynamic performance.

• Communications infrastructure

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's package option addendum to confirm the reel quantity and tape specifications. Ensure that the procurement documentation matches the exact part number variant required for the design. Cross-reference the datasheet revision history to confirm the component status is production data rather than preview. Confirm thermal management requirements align with the junction-to-ambient resistance metrics provided in the specification tables.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring direct RF sampling at frequencies up to 3 GHz with high linearity. The 2.6 GSPS sampling rate suits applications needing wide instantaneous bandwidth. Consider the power dissipation of 2.6 W per channel at typical operating conditions for thermal design. Evaluate the need for internal DDCs to simplify downstream FPGA or processor interfaces. Verify that the system clock and SYSREF distribution can meet the strict timing requirements for JESD204B synchronization.

Analog To Digital Converters (ADC) Part Context

The ADC32RF54 is part of the ADC32RF5x family, which also includes the ADC32RF55 operating at 3.0 GSPS. Both devices share the same 64-pin VQFN package and functional block diagram, differing primarily in maximum sampling speed. This family targets high-performance radar and communications applications where low phase noise and high dynamic range are critical. The RTD package designation indicates a 9 mm x 9 mm VQFN form factor suitable for dense PCB layouts.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC32RF55 serves as a higher-speed alternative within the same family, offering 3.0 GSPS sampling while maintaining pin compatibility. Designers requiring lower sampling rates might consider the ADC32RF42 series, though it features different packaging and interface characteristics. No direct cross-brand replacements are documented in the official datasheet; substitute selection requires careful verification of electrical parameters and pinout compatibility.
