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

TPS3808, TPS75005, TPS386000 Setting the SVS Voltage Monitor Threshold

The purpose of a power distribution network (PDN) is to provide clean and reliable power to active devices in the system. The printed circuit board (PCB) is a critical component of the system-level PD

This application report helps users to understand set up and use the programming timings in the register-based touch screen controller (TSC) devices. It displays the timings functions and discusses the effect on the system interface traffic and on the system power consumption.

This document describes how to use the mulit-channel buffered serial ports (McBSP) in the Texas Instruments (TI) TMS320C6000™ digital signal processor (DSP) as a high-speed data communication port.

One McBSP of one C6000™ DSP device can be connected to a McBSP on another C6000 DSP device to serve as a high-speed data communication port. Typically McBSPs of similar device numbers a
