Optical coherence tomography (OCT) imaging is a high-resolution sub-surface non-invasive imaging technique that has become increasingly popular in hospitals and clinics for various applications for structural and quantitative imaging.

As an increasing number of OCT equipment manufacturers choose to use digital signal processors (DSP) to design their OCT systems it becomes extremely important t

Whenever engineers who need or use isolation amplifiers get together and talk about the improvements they would like to see most the big three - cost size performance - are likely to be mentioned. The industrial or medical equipment manufacturer often has to make a choice of either buying an isolation amplifier or building his own. Cost is the key criterion for such a decision but there are o

PRIME PLC Device Firmware Upgrade Written by Chinese engineers

The TMS470 family of ARM7 microcontrollers has four modes of operation: Standby Idle Halt and Run. The device starts in Run mode and the other three are considered low-power modes. Additional power savings are available by disabling the flash memory.This application report explains how to change into the low-power modes and how to disable and enable the flash.This application report also de

TPS2546; TPS2546-Q1 TPS2546/TPS2546Q1 Production Silicon Checklist

A bootloader enables field updates of application firmware. A controller area network (CAN) bootloader enables firmware updates over the CAN bus. The CAN bootloader described in this application report is based on the Hercules™ ARM® Cortex™-R4 microcontroller. This application report describes the CAN protocol used in the bootloader and details each supported command.

Due to memory constraints on data page 0 Multi-Channel Buffered Serial Port (McBSP) registers are accessed using a sub-address scheme. This document discusses how data is accessed through the sub-address registers. A code listing is included.

The LMH2121 is an accurate fast responding power detector/RF envelope detector. Its response betweenan RF input signal and DC output signal is linear. The typical response time of 165 ns making it suitablefor an accurate power setting in handsets during a rise-time of RF transmission slots. It can be used in allpopular communication standards 2G/3G/4G/WAP.

The LM88 is a dual remote diode temperature sensor with three digital comparators and has three opendrainoutputs (O_SP0 O_SP1 and O_CRIT) that can be used as interrupts or to signal system shutdown.

Over the past few years electronic products and especially those which fall within the category ofConsumer Electronics have been significantly reduced in physical size and weight. This documentprovides information about the techniques used to mount CSP size components.

The Texas Instruments (TI)(tm) TMS320C6x digital signal processor (DSP) architecture with its RISC-like instruction set flexible parallelism and conditional execution can be used in non-typical DSP applications from microcontroller-type to FPGA/ASIC/data flow-type tasks. This paper uses code examples to explore ways to efficiently handle bit manipulation address manipulation and dataflow con

Development platforms available for digital signal processor (DSP) designers today are mainly the evaluation module (EVM) and the DSP starter kit (DSK). Executable code generated on these two platform

The SM72442 MPPT digital controller and SM72295 photovoltaic full bridge drivers are designed to controlhigh-efficiency DC/DC conversion used in photovoltaic applications. This application report details theusage of those devices in a battery charging application. The reference design is meant to provide supportfor a wide variety of implementations however unless otherwise noted this refe

Configuring the bq27350 Data Flash

This application report discusses a solution to the additional power required in those PoE applications that exceed the power requirements defined in the current IEEE802.3af standard.

The short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter

This application report presents two hardware solutions for interfacing the TLV1544 10-bit low-power analog-to-digital converter (ADC) to the TMS320C50 16-bit fixed-point digital signal processor (DSP). The report describes the interface hardware and shows three C-callable software routines which support the data transfer. In addition it provides useful hints on the design of a typical system pow
