Application Notes
- Power Supply Design for the ADS41xx (Rev. A)PDF, 401 Кб, Версия: A, Файл опубликован: 29 дек 2011
System designers traditionally power the high-speed data converter in their systems from a low-noise, low-dropout linear regulator (LDO) in order to achieve the performance described in the analog-to-digital converter (ADC) data sheet. However, LDOs inherently are not very power efficient. Switching regulators, on the other hand, offer good power efficiency but typically come with higher output no - High-Speed Analog-to-Digital Converter BasicsPDF, 1.1 Мб, Файл опубликован: 11 янв 2012
The goal of this document is to introduce a wide range of theories and topics that are relevant tohigh-speed analog-to-digital converters (ADC). This document provides details on sampling theorydata-sheet specifications ADC selection criteria and evaluation methods clock jitter and other commonsystem-level concerns. In addition some end-users will want to extend the performance capabil - Band-Pass Filter Design Techniques for High-Speed ADCsPDF, 733 Кб, Файл опубликован: 27 фев 2012
Several well-known methods exist for designing passive inductor-capacitor (LC) filters with resistive load terminations. However, when LC filters are used to drive the analog input pins of a high-speed analog-to-digital converter (ADC), special consideration must be given to the ADC input impedance. Not accounting for the ADC input impedance often results in a filter design that does not meet the - QFN Layout GuidelinesPDF, 1.3 Мб, Файл опубликован: 28 июл 2006
Board layout and stencil information for most Texas Instruments Quad Flat No-Lead (QFN) devices is provided in their data sheets. This document helps printed-circuit board designers understand and better use this information for optimal designs. - CDCE62005 as Clock Solution for High-Speed ADCsPDF, 805 Кб, Файл опубликован: 4 сен 2008
TI has introduced a family of devices well-suited to meet the demands for high-speed ADC devices such as the ADS5527 which is capable of sampling up to 210 MSPS. To realize the full potential of these high-performance products it is imperative to provide a low phase noise clock source. The CDCE62005 clock synthesizer chip offers a real-world clocking solution to meet these stringent requirements - Why Use Oversampling when Undersampling Can Do the Job? (Rev.

This application report presents phase noise data taken on the CDCE72010 jitter cleaner and synchronizer PLL device. The phase noise performance of the CDCE72010 depends on the phase noise of the reference clock VCXO clock and the CDCE72010 itself. This application report shows the phase noise performance at several of the most popular CDMA frequencies. This data helps the user to choose the rig - CDCE72010 as a Clocking Solution for High-Speed Analog-to-Digital ConvertersPDF, 424 Кб, Файл опубликован: 8 июн 2008
Texas Instruments has recently introduced a family of devices suitable to meet the demands of high-speed high-IF sampling analog-to-digital converters (ADCs) such as the ADS5483 which is capable of sampling up to 135 MSPS. To realize the full potential of these high-performance devices the system must provide an extremely low phase noise clock source.
