Texas Instruments ADS58J63EVM

Overview

ADS58J63EVM from Texas Instruments is an evaluation module designed to characterize the ADS58J63 4-channel, 500-MSPS, 14-bit JESD204B analog-to-digital converter. It integrates the LMK04828 clock generator, transformer-coupled analog inputs (0.25–750 MHz), FMC-compatible high-speed serial data output, and USB-based configuration interface. The EVM supports complex digital mixer mode (Fs/4) and bypass mode for ADC performance validation in RF receiver and communications test systems.

For engineers reviewing the ADS58J63EVM datasheet, ADS58J63EVM pinout, ADS58J63EVM application, or ADS58J63EVM equivalent, this page provides verified hardware configuration details, JESD204B lane setup (4-lane, 491.52-MSPS sampling), LMK04828 clocking options (internal VCXO, external reference, or external clock injection), and interoperability with TSW14J56EVM via HSDC Pro software for real-time data capture and spectral analysis.

Technical Context

The ADS58J63EVM implements a complete signal chain for evaluating high-speed ADCs using JESD204B subclass 1 compliance. It routes analog inputs through 1:1 transformers to four independent channels (AIN A–D), conditions clock signals via LMK04828 with selectable PLL configurations (VCXO-locked or externally referenced), and delivers serialized data over a standard FMC connector supporting up to 12.5 Gbps per lane.

Hardware control is managed through a dedicated USB interface (FTDI-based) enabling register-level access to both the ADS58J63 and LMK04828 via the ADS54Jxx GUI. Configuration files define fixed operating modes - including Fs/4 complex mixer + decimate-by-2 (ADS5xJ6x_2x_Fs_4_mode_0.cfg) and full-rate bypass (ADS54J66_bypass_4421.cfg) - ensuring repeatable test conditions aligned with TI's published SNR (69.73 dBFS) and SFDR (95.6 dBFS) measurements.

FAQ

What is the primary function of the ADS58J63EVM?

The ADS58J63EVM is a Texas Instruments evaluation module built to validate the performance of the ADS58J63 4-channel, 14-bit, 500-MSPS JESD204B ADC. It provides transformer-coupled analog inputs, LMK04828-based clock generation, FMC-hosted serial data output, and USB-controlled register access. The ADS58J63EVM enables engineers to measure key metrics like SNR (69.73 dBFS) and SFDR (95.6 dBFS) under real-world conditions using HSDC Pro and TSW14J56EVM integration.

Does the ADS58J63EVM support external clock sources?

Yes, the ADS58J63EVM supports three clocking modes: internal VCXO-driven (default), external reference input via CLKIN (J12), and direct external ADC sampling clock injection via EXT_ADC_CLK (J6). When using external clock injection, C47/C48 must be relocated to R35/R39, and LMK04828 outputs must be powered down to minimize noise. The ADS58J63EVM maintains SYSREF and FPGA clock distribution even in external clock mode, preserving JESD204B subclass 1 timing integrity.

Which software tools are required to operate the ADS58J63EVM?

Two software tools are mandatory: the ADS54Jxx GUI for low-level register configuration of the ADS58J63 and LMK04828, and High Speed Data Converter Pro (HSDC Pro) for data capture, FFT analysis, and system-level validation when paired with the TSW14J56EVM. The ADS58J63EVM uses preloaded configuration files (e.g., ADS5xJ6x_2x_Fs_4_mode_0.cfg) to set JESD204B lane count, sample rate, and digital signal processing mode - all accessible within the ADS54Jxx GUI's Low Level View tab.

Can the ADS58J63EVM be used without the TSW14J56EVM?

No - the ADS58J63EVM does not include on-board data capture or storage capability. Its FMC connector delivers serialized JESD204B data exclusively to an external host such as the TSW14J56EVM, which handles deserialization, buffering, and PC transfer. While the ADS58J63EVM can be powered and configured independently via USB, meaningful ADC performance evaluation (e.g., SNR, SFDR, FFT plots) requires HSDC Pro running with the TSW14J56EVM connected via USB 3.0 and synchronized via the FMC interface.

What are the power requirements for the ADS58J63EVM?

The ADS58J63EVM requires a single +5-V DC input rated for ≥3 A delivered via the J14 power connector. This powers the ADS58J63 ADC, LMK04828 clock generator, signal conditioning circuitry, and onboard logic. Power sequencing is managed internally; no auxiliary voltages (e.g., 3.3 V, 1.8 V) are user-supplied. The board includes LED indicators (D1–D10) for status monitoring, and SW1 provides manual ADC hardware reset. Stable low-noise power is critical - TI specifies ≤10 mVpp ripple to maintain measured SNR performance.
