Texas Instruments TSW12D1620EVM-CVAL

Overview

TSW12D1620EVM-CVAL from Texas Instruments is an evaluation module designed to characterize the radiation-hardened ADC12D1620QML-SP dual-channel 12-bit analog-to-digital converter operating at up to 1.6 GSPS (dual-channel) or 3.2 GSPS (single-channel), with high-speed LVDS data output, integrated temperature monitoring via TMP461-SP, and USB-based register programming via FTDI interface.

For engineers reviewing the TSW12D1620EVM-CVAL datasheet, TSW12D1620EVM-CVAL pinout, TSW12D1620EVM-CVAL application, or TSW12D1620EVM-CVAL equivalent, this EVM supports full performance validation of RF-sampling ADCs in space-grade signal acquisition systems requiring DC–3 GHz analog input bandwidth, external low-noise clocking (0.2–1.6 GHz), and FPGA-based high-speed data capture via FMC interface.

Technical Context

The TSW12D1620EVM-CVAL interfaces directly with the ADC12D1620QML-SP device using a transformer-coupled clock input network and LMH5401-SP fully differential amplifier for single-ended-to-differential conversion. It implements SPI-based register configuration over USB via an onboard FTDI USB-to-serial bridge connected to the ADC's serial programming interface.

Signal path architecture includes optional differential input networks supporting DC–>3 GHz, on-board LDO and buck regulators (TPS7A4501-SP, TPS50601A-SP, TPS7H1101A-SP), and real-time temperature monitoring using both TMP461-SP and MSP430FR5969-SP microcontroller. Data capture requires the TSW14DL3200EVM via FMC connector and HSDC Pro software.

FAQ

What is the primary purpose of the TSW12D1620EVM-CVAL?

The TSW12D1620EVM-CVAL is a dedicated evaluation module for the ADC12D1620QML-SP radiation-hardened dual-channel 12-bit ADC. It enables full characterization of sampling performance, LVDS timing integrity, thermal behavior, and register-level configuration in space-grade signal acquisition systems. The TSW12D1620EVM-CVAL provides all necessary signal conditioning, power regulation, and host interface logic to validate the ADC under realistic RF-sampling conditions.

Does the TSW12D1620EVM-CVAL include an onboard clock generator?

No - the TSW12D1620EVM-CVAL relies exclusively on an external low-noise clock source applied via the DEVCLK SMA connector. Documentation explicitly states that onboard clock generation (e.g., LMX2615-SP) is planned for future revisions only and is not implemented in the current TSW12D1620EVM-CVAL hardware. Users must supply a 0.2–1.6 GHz clock signal at +9 dBm (2.2 VPP into 50 Ω), adjusted for filter and cable losses.

Which software tools are required to operate the TSW12D1620EVM-CVAL?

Three software components are mandatory: (1) TSW12D1620EVM-CVAL GUI for ADC register configuration and calibration, (2) HSDC Pro software for data capture and spectral analysis, and (3) TSW14DL3200EVM firmware (e.g., TSW14DL3200_FIRMWARE_COMPONENT_MODE_800M.bin) loaded onto the companion capture board. All are available from TI's official tool page for TSW12D1620EVM-CVAL and require Windows OS (XP/7/8/10).

How is analog input configured on the TSW12D1620EVM-CVAL?

The TSW12D1620EVM-CVAL supports both single-ended (AINI/AINQ SMA inputs) and differential (VINI±/VINQ±) analog inputs. A transformer-coupled path and LMH5401-SP fully differential amplifier enable wideband operation from DC to >3 GHz. Optional differential network configurations require discrete component changes per User's Guide Section 1.1 - no jumpers or switches provide automatic reconfiguration.

Can the TSW12D1620EVM-CVAL operate independently without the TSW14DL3200EVM?

No - the TSW12D1620EVM-CVAL does not include on-board memory or USB data streaming capability. Its LVDS output is routed exclusively to the FMC connector and must be captured by the TSW14DL3200EVM (or compatible FMC-LVDS capture platform). The TSW12D1620EVM-CVAL GUI handles only register programming and calibration; raw sample data acquisition and PC transfer depend entirely on the companion capture board and HSDC Pro software.
