This application note demonstrates the use of TI?s Zero Iq Reverse Polarity Protection Smart Diode Controllers- LM74610-Q1 as a highly effective solution in redundant N+1 power supply arrangement. It

This document describes two options used to supply power to the Texas Instruments (TI)(tm) TMS320C206 digital signal processor (DSP). The TMS320C206 DSP requires 3.3V for the CPU and 5.0V for the I/O. The first solution applies when a design already has a regulated 5.0V power supply and requires only a 3.3V (LDO) Low Dropout regulator. The second solution applies an unregulated voltage input t

The analog interface circuit (AIC), also called a modem Codec, is a complete data acquisition system on a chip for general-purpose telephony/speech applications such as: modem analog interface, voice-band audio processing, noise cancellation/suppression, hands-free communication, security voice systems, tone generation, echo cancellation, voice-over-internet protocol (VoIP), and industrial process control. The AIC is normally interfaced to a digital signal processor (DSP). This approach has a number of advantages and cost-saving benefits that cannot be realized with traditional Codec analog interfacing. The benefits include:

• lower cost,
• simple interface design and fewer components,
• greater system reliability due to fewer components,
• lower power consumption,
• higher performance, and
• high programmability.

Reworking LLP Chip Scale Package

When we say that an electric motor is a device that transforms electric power into mechanical power we say two things. First that the motor is ?and behaves as ?a transformer. Second that it stands at the dividing line between electrical and mechanical phenomena. In the case of permanent magnet motors this power transformation works in both directions so that the electrical impedance depends on

High-speed digital-to-analog converters (DACs) most often use a transformer-coupled output stage. In applications where this configuration is not practical, a single op amp differential to single-end

This application report presents the basic concept and methodology to develop the TSC2301 touch screen keypad audio and GPIO drivers on the Windows CE (WinCE) operating system (OS). The drivers are not tied to any specific processor platform. They therefore can be called generic and are reusable for any host processor or platform with minimal additional coding.

The EDMA3 is a high-performance multi-channel module for the TMS320C64x+ DSP that allows you to program a wide variety of transfer geometries and sequences. In addition it interacts with the switch central resource (SCR) fabric to compete for bus and read/write access resources. The EDMA3 prioritization scheme is summarized and various program registers are introduced in this application report.

This application note first provides a summary of empirical results found when master to slave node synchronization is measured with Synchronous Ethernet mode enabled. Background information is then provided describing the operation of and topological constraints associated with Synchronous Ethernet mode. Typical applications are then described followed by empirical data which clearly demonstrate

Comparing the PCI2050B to the PCI2050

This application report discusses design implementation and focuses on how to provide input signals andclock to the ADC14DS105 by reading data from its serial interface. Also the unique output drive detailsare reviewed.

This document discusses how a designer can improve the performance of the DSP-based system Hard Disk Drive (HDD) memory. The case study approach is used to address issues of drive component integration. Problems and solutions are presented.

Core Voltage Accumulation

The 'C31 bootloader is expected to be used only at reset and then the 'C31 will stay in MCBL mode the rest of the time. It is sometimes convenient that once loading is done the MCBL/MP pin is changed to enable the microprocessor memory map. This document discusses a technique to change from bootloader mode to microprocessor mode on-the-fly.

This application report discusses the use of LMV225 Linear-In-dB RF Power Detector In a CDMA2000 1Xand EV_DO mobile station and access terminal.

This application note describes a monolithic operational amplifier which has input error currents in theorder of 100 pA over a −55°C to 125°C temperature range. Instead of FETs the circuit used bipolartransistors with current gains of 5000 so that offset voltage and drift are not degraded. A powerconsumption of 1 mW at low voltage is also featured.A number of novel circuits that make use

The Dual Clock Compare (DCC) may be configured to provide autonomous real-time monitoring of the average frequency of a signal. This application report illustrates a configuration in which the DCC monitors the average PLL frequency. This comparison triggers an error when the average PLL falls out of a specified range. The accuracy window and the duration over which the frequency is averaged must
