Texas Instruments ADC12J2700EVM

Overview

ADC12J2700EVM from Texas Instruments is an evaluation board designed to characterize the ADC12J2700 12-bit, 2.7 GSPS analog-to-digital converter using JESD204B serial interface. It integrates LMX2581 and LMK04828 clock generators, supports transformer-coupled RF input (400 MHz–3 GHz), and delivers high-speed data via FMC connector to TSW14J56EVM for capture and analysis.

For engineers reviewing the ADC12J2700EVM datasheet, ADC12J2700EVM pinout, ADC12J2700EVM application, or ADC12J2700EVM equivalent, this page provides verified setup guidance, JESD204B lane configuration limits, onboard clocking options (2.7 GSPS/1.6 GSPS), HSDC Pro software integration, and hardware-level troubleshooting for RF sampling validation.

Technical Context

The ADC12J2700EVM enables full evaluation of the ADC12J2700 device's performance at up to 2.7 GSPS with JESD204B output (L = 1–4 lanes, K = 2–32, scrambling enabled). It uses an FTDI USB-to-SPI bridge for register-level control of the ADC, LMK04828, and LMX2581 via a dedicated GUI.

Hardware synchronization relies on CPU_RESET button activation to initialize the JESD204B link in the TSW14J56EVM FPGA; LED status (D1–D8, FPGA_DONE) confirms link state, clock lock, and data capture readiness per documented default patterns in SLAU560.

FAQ

What is the primary purpose of the ADC12J2700EVM?

The ADC12J2700EVM is a dedicated evaluation board for the ADC12J2700 12-bit, 2.7 GSPS analog-to-digital converter. It provides complete hardware and software infrastructure-including clock generation (LMX2581/LMK04828), JESD204B interface, transformer-coupled RF input, and USB-based register control-to validate dynamic performance, timing margins, and system-level integration of the ADC12J2700 in real-world wideband applications.

Which data capture board is required to use the ADC12J2700EVM?

The ADC12J2700EVM must be used with the TSW14J56EVM data capture board. The two boards connect via FMC interface, enabling JESD204B serial data transfer. The TSW14J56EVM handles FPGA-based decoding, memory buffering, and USB upload to PC, and its firmware defines supported lane configurations (L = 1, 2, 4, 8) and lane rates (2–10 Gb/s) for the ADC12J2700EVM.

Does the ADC12J2700EVM support external clocking?

Yes, the ADC12J2700EVM supports external clocking through dedicated SMA inputs (DEVCLK and LMKCLK), though it ships with onboard clocking enabled. For frequencies ≤3100 MHz, both DEVCLK and LMKCLK must be set to the same frequency; above 3100 MHz, LMKCLK must be half of DEVCLK. External clocking requires bandpass filtering and low-noise signal sources per TI's recommended setup in SLAU560.

How is the ADC12J2700EVM configured and controlled?

The ADC12J2700EVM is configured using two software tools: the standalone ADC12J2700EVM Configuration GUI (for register-level control of ADC12J2700, LMK04828, and LMX2581) and the High-Speed Data Converter Pro (HSDC Pro) software (for data capture, FFT analysis, and system-level testing). Communication occurs over mini-USB via an onboard FTDI USB-to-SPI bridge.

What are the key hardware features integrated on the ADC12J2700EVM?

The ADC12J2700EVM integrates a transformer-coupled RF input path (400 MHz–3 GHz), LMX2581 for ADC sampling clock generation, LMK04828 for FPGA reference clocks and optional ADC clocking, LM95233 temperature sensor, FMC connector for JESD204B data output, and USB interface for SPI programming. All critical signals are routed with impedance-controlled traces to preserve signal integrity at multi-GHz sample rates.
