Many applications require multiple analog-to-digital converters (ADC) in a system. Daisy chaining multiple ADCs enables the use of a single data receiver or a small FPGA. It offers easy and minimal digital routing. This application report describes how multiple ADCs (ADS8410/13) work in a daisy-chain mode. The device offers a high-speed (200 Mbps) LVDS serial interface. This application report als

This application report presents the new features available in Code Composer Studio?(CCS) v2 that facilitate efficient project management. The CCS Project Management system has been broadened and improved to include: multi-project/multi-configuration support source code control as well as the ability to interface to external build processes.The material presented in this application note foc

This application report presents phase noise data taken on the Texas Instruments' CDCE62005 jitter cleaner and synchronizer PLL. The phase noise performance of the CDCE62005 depends both on the phase noise of the reference clock and the CDCE62005 itself. This application report shows the phase noise performance at the most popular CDMA frequencies and helps the user to choose the right clocking so

In 1821 Thomas Seebeck discovered the physical phenomenon that when you join two dissimilar metalson both ends and heat one end a continuous current is created in the thermoelectric circuit . If the otherend is broken a voltage can be measured that is proportional to the temperature difference between theheated junction (measuring or hot junction) and the open end (reference or cold ju

How do I set and use interrupts on C for the Texas Instruments (TI)(tm) TMS320C6x DSP?Writing Interrupt Service Routines (ISRs) in C is straightforward as long as you follow the simple rules set out in this document. The problem consists of four parts: - Selecting the interrupt source and writing the ISR- Creating and initializing the interrupt vector table- Setting the proper register

The DRV411 is a signal-conditioning integrated circuit for use in closed-loop magnetic current-sensor modules. The DRV411 is designed to interface with symmetrical indium antimonide (InSb) and gallium arsenide (GaAs) type Hall sensors. Symmetrical Hall elements have their input and output impedances closely matched. The DRV411 contains excitation and conditioning circuitry that significantly red

The 'C5x DSK is designed to directly connect to a microphone and an 8-ohm speaker via RCA jacks. The I/O RCA jacks are directly connected to the dual A/D and D/A converter called the Analog Interface Circuit (AIC). In some instances the microphone does not generate the signal level required for the AIC to detect and convert the signal. It is suggested that a dynamic or amplified (pre-amp) microph

Analog Applications Journal November 2000 Issue

The first article of this two-part series, published in the February 2001 issue of Analog Applications Journal, discussed the THS8083EVM hardware, a TI evaluation module featuring the THS8083 (a triple 8-bit high-speed ADC with integrated PLL for component video and PC graphics digitizing) and the THS8134 (a triple 8-bit video DAC). Having presented an overview of the features and EVM block diagram in the earlier article, we now turn our attention to the design of the complex programmable logic device (CPLD) on the EVM and the design of the PC-user software.

First we will describe the overall functionality of the CPLD, which operates in combination with the THS8083 to enable the display of a digitized PC graphics or video signal on an LCD flat-panel display connected to the board. Then we will focus on the implementation of the communication protocol between the PC and the EVM that eliminates the need for a microcontroller and therefore is more generally applicable as a methodology for rapid hardware prototyping. We will illustrate some of the EVM and THS8083 features using the PC software graphical user interface (GUI); and, in particular, we will implement an algorithm for white-balance calibration.
