This report summarizes the results of PCIe Gen 3.0 add-in card compliance testing using TI’s low-power 12.5 Gbps 8-channel advanced linear repeater. The advanced linear repeater is placed in a mid-channel configuration between a PCIe Gen 3.0 graphics card and a compliance base board (CBB) and tested for jitter eye mask and TX preset compliance. The results demonstrate the excellent signal condit

At first glance, a welding machine, a fetal heart monitor, a tractor, a bulldozer, and a PC have little in common, but all of them have a machine-man interface to communicate information. If your sys

Use this guide as the first step in troubleshooting any issues while using the PGA411-Q1 device. This guide includes example waveforms and information on faults that assist in the process to troublesh

Texas Instruments applications personnel have decades of collective experience designing active filters using operational amplifiers (op-amps). This information has been made available interactively through Texas Instruments KnowledgeBase system. Although not every filter design topic can be covered in the KnowledgeBase format a very large percentage of filter design problems have been addressed.

The first part of the Application Report describes the generation of DTMF signals using the Microcontroller MSP430. Following an explanation of the most important specifications which are involved, th

This application report helps TI mmWave Radar sensor designers navigate the series of tasks and key concerns when designing, manufacturing and validating a new mmWave sensor board. This document is only concerned with the RF portions of the design. It is beneficial for PCB designers that do not have experience with RF PCB design at mmWave frequencies. This document is applicable to sensor designs using IWR/ AWR mmWave Radar chips.

Voltage Mode Boost Converter Small Signal Control Loop Analysis Using the TPS61030

This application report contains implementation instructions for the Serial Rapid I/O (SRIO) interface on the TMS320C6455 DSP device. The approach to specifying interface timing and physical requirements for the SRIO interface is quite different than previous approaches for other interfaces.

Serial Rapid I/O is an industry-standard high-speed switched-packet interconnect. Physical layer data t

This document is intended to guide MPLAB Harmony v2 users on how to develop applications using MPLAB Harmony V3.

This reference design was created to help those needing to power the Marvell PXA270 and doing so by implementing a highly simplistic and efficient design that uses the TPS65021 power management unit.

LB-38 Wide Range Timer

Once an analog-to-digital converter (ADC) and a driver/interface have been selected for a given application, the next step to achieving excellent performance is laying out the printed circuit board (P

This application report discusses how to design a simple and ultra low-power grip detector BoosterPack for the MSP430 LaunchPad™. The PINOSC feature in every msp430G2xx2 and msp430G2xx3 device makes it possible to eliminate all the external components when implementing a capacitive touch design. All the components used in the grip detector such as capacitive sensors LEDs are all integrate

This paper shows the implementation of a low cost active noise control (ANC) on the DSP Starter Kit TMS320C26 [1]. The ANC system uses a filtered-x LMS adaptive algorithm [2] with on/off-line path cancellation estimates [345]. The system consists of an error microphone plus a signal amplifier two powered speakers (primary and secondary source) and the controller (the DSP Starter Kit). The t

TI’s DRV9x family of parts are motor driver integrated circuits (ICs) with an integrated MSP430 core and 3-phase brushless DC (BLDC) predriver. These ICs require Code Composer Studio™ (CCS), device drivers, and MSP430UIF tools to communicate via the JTAG communication. This document details the entire installation and programming tool setup using CCS. This integrated development environment (IDE) offers full debugging and developmental capabilities. A detailed pictorial step-by-step description of each block is also included in the document. All specific files needed for the DRV9x are included in the software development kit (SDK) install package, CCS must be installed separately.
