Texas Instruments ADC3660EVM

Overview

ADC3660EVM from Texas Instruments is an evaluation module designed to characterize the ADC3660 dual-channel, 14-bit, 65 MSPS analog-to-digital converter. It supports serial CMOS (SCMOS) data output up to 250 Mbps, onboard CDCE6214 clocking, transformer/FDA-coupled analog inputs, and real-time power monitoring via INA226 shunt monitors on AVDD and IOVDD rails.

For engineers reviewing the ADC3660EVM datasheet, ADC3660EVM pinout, ADC3660EVM application, or ADC3660EVM equivalent, this module enables rapid validation of high-speed sampling performance, decimation filter behavior (bypass/real/complex modes), and low-noise signal chain integration with TSW1400EVM data capture and HSDC Pro software.

Technical Context

The ADC3660EVM implements a complete signal acquisition testbed for the ADC3660 IC, featuring FMC connectivity, configurable clock routing (internal CDCE6214 or external SMA sources), and hardware-modifiable sampling/data clock paths (e.g., DNI R176, replace C129 with 0-Ω resistor). It supports three operational modes: Bypass (25 MSPS, 16-bit), Real Decimation (65 MSPS → 4.0625 MSPS, 16× decimation), and Complex Decimation (65 MSPS → 8.125 MSPS I/Q, 8× decimation with 9 MHz NCO).

Power measurement is integrated via two INA226 current monitors measuring +1.8 VDC AVDD and IOVDD rail consumption, with real-time readout in the ADC35XX GUI. The board includes jumper-configurable power options (J8 2–3 for USB 5 V, J8 1–2 for external +5 V EXT) and supports both transformer-coupled and single-ended clock inputs.

FAQ

What is the primary purpose of the ADC3660EVM?

The ADC3660EVM is a dedicated evaluation module for the ADC3660 dual-channel, 14-bit, 65 MSPS analog-to-digital converter. Its purpose is to enable engineers to validate dynamic performance (SNR, SFDR), configure decimation modes (Bypass, Real, Complex), verify clocking architecture, and measure real-time power consumption on AVDD and IOVDD rails - all using TI's HSDC Pro and ADC35XX GUI software tools. It is not intended for end-product integration.

Does the ADC3660EVM support external clocking, and what hardware modifications are required?

Yes, the ADC3660EVM supports external clocking for both sampling and data clocks. Required hardware modifications include: DNI R176; replace C129 with a 0-Ω resistor; DNI R32 and R40; install R36 and R37; and connect sampling clock to J8 and DCLKIN to J15. These changes route external signals directly to the ADC3660 device while disabling the onboard CDCE6214 clock path - as documented in Section 5.1 of the SBAU356 user's guide.

How is power consumption measured on the ADC3660EVM?

Power consumption on the ADC3660EVM is measured using two INA226 current shunt monitors - one per +1.8 VDC rail (AVDD and IOVDD). Current readings are digitized and displayed in real time on the "Power Meter" tab of the ADC35XX GUI. Users click the "Measure Power" button to refresh values, enabling accurate characterization of rail-specific power under different decimation modes and input conditions.

Which software tools are required to operate the ADC3660EVM?

Operation of the ADC3660EVM requires two TI-provided software tools: the High-Speed Data Converter (HSDC) Pro software for data capture and FFT analysis, and the ADC35XX Configuration GUI for device register programming, clock configuration, and decimation mode selection (Bypass, Real, Complex). Both tools must be installed and used in conjunction with the TSW1400EVM data capture board and FPGA interposer card.

Can the ADC3660EVM be used in production systems?

No, the ADC3660EVM is strictly an evaluation module intended for laboratory use by technically qualified engineers during R&D and feasibility testing. TI's Standard Terms for Evaluation Modules explicitly prohibit its use in finished products, commercial distribution, consumer applications, or production environments. It lacks production-grade qualification, long-term supply assurance, and regulatory certifications required for end-equipment deployment.
