Texas Instruments ADC32RF80EVM

Overview

ADC32RF80EVM from Texas Instruments is an evaluation module designed to characterize the ADC32RF80 dual-channel, 14-bit, 3-GSPS RF-sampling analog-to-digital converter with JESD204B interface. It supports both bypass (full-rate LMFS82820) and digital down-conversion (DDC) modes, features onboard LMK04828 clock generator and optional LMX2582/LMX2592 synthesizer, and delivers transformer-coupled analog input (30 MHz–3 GHz) for high-fidelity RF signal acquisition in radar and communications test benches.

For engineers reviewing the ADC32RF80EVM datasheet, ADC32RF80EVM pinout, ADC32RF80EVM application, or ADC32RF80EVM equivalent, this page provides verified hardware configuration guidance, JESD204B lane setup (8-lane, 2-channel), clocking architecture details (SYSREF synchronization, external/internal clock selection), and validated integration paths with TSW14J56 capture card and HSDC Pro software.

Technical Context

The ADC32RF80EVM implements a complete signal chain for evaluating the ADC32RF80's RF sampling capability: analog inputs are transformer-coupled for 50-Ω single-ended drive up to 3 GHz; clocking is configurable via external SMA, LMK04828 (for SYSREF + FPGA device clock), or LMX2582/LMX2592 (ultra-low-jitter ADC sampling clock); jumper JP3 selects clock source, and SW1 enables hardware reset of the ADC.

JESD204B data transmission uses an FMC-HPC connector supporting 8 lanes at up to 12.5 Gbps per lane; DDC mode enables programmable NCO tuning and decimation (e.g., 8×) with real-time frequency translation; bypass mode outputs full-rate 14-bit samples in LMFS82820 format (8 lanes, 2 channels, 20 samples/frame/channel) for wideband capture applications.

FAQ

What is the primary function of the ADC32RF80EVM?

The ADC32RF80EVM is an evaluation module built to validate the performance of the ADC32RF80 RF-sampling analog-to-digital converter. It provides complete hardware and software infrastructure-including transformer-coupled analog inputs, multiple clocking options (LMK04828, LMX2582), JESD204B FMC interface, and TI's ADC32RFxx EVM GUI-to enable engineers to configure, capture, and analyze high-speed digitized RF signals up to 3 GSPS. The ADC32RF80EVM itself does not perform conversion; it hosts and interfaces the ADC32RF80 for lab-based characterization.

Which ADC models does the ADC32RF80EVM support besides ADC32RF80?

The ADC32RF80EVM is compatible with the entire ADC32RFxx family, including ADC32RF45, ADC32RF44, ADC32RF42, ADC32RF82, and ADC31RF80 (Channel A only). This cross-compatibility is confirmed in TI's SLAU620E User's Guide, which documents identical hardware layout, jumper configurations (e.g., JP3 for clock selection), and GUI support across all variants. However, functional modes differ: ADC32RF80 supports both DDC and bypass modes, while ADC32RF45 supports bypass LMFS82820 but not DDC, and ADC32RF44 is limited to 2.6 GSPS maximum sample rate.

Does the ADC32RF80EVM include an onboard clock generator?

Yes, the ADC32RF80EVM integrates the LMK04828 low-noise clock generator as its primary onboard clock solution. The LMK04828 provides SYSREF and device clock to the ADC32RF80 and simultaneously supplies synchronized clocks to the FMC-connected FPGA or TSW14J56 capture card. It also supports optional use of LMX2582 or LMX2592 as an ultra-low-jitter ADC sampling clock source-configured via solder jumpers and JP3 selection-enabling rigorous jitter sensitivity analysis for the ADC32RF80.

How is JESD204B configured on the ADC32RF80EVM?

The ADC32RF80EVM implements JESD204B subclass 1 using an FMC-HPC connector with 8 high-speed serial lanes operating at up to 12.5 Gbps. Configuration is managed through TI's ADC32RFxx EVM GUI and HSDC Pro software: the GUI sets ADC-side parameters (LMFS values, K, N', N), while HSDC Pro configures the TSW14J56 receiver side. Validated configurations include LMFS82820 (bypass, 5-sample mode) and LMFS8821 (DDC, 8× decimation), both requiring strict parameter alignment between ADC and FPGA to establish link synchronization and deterministic latency.

What external hardware is required to operate the ADC32RF80EVM?

To fully operate the ADC32RF80EVM, you must provide: a TSW14J56EVM data capture card (connected via FMC), two independent +5-VDC power supplies (one for the ADC32RF80EVM, one for the TSW14J56), a Windows PC with LabVIEW Runtime and HSDC Pro v4.2+, a low-noise RF signal generator (10 MHz–3 GHz, <500 fs jitter), and a bandpass filter matching your input frequency. The ADC32RF80EVM kit itself includes only the evaluation board, mini-USB cable, and power supply cable-no signal sources, filters, or capture hardware are bundled.
