Coherency is a well-known requirement when using FFT techniques to examine the spectrum of the output of an analog-to-digital converter. SNRBoost(3G) technology results in loss in coherency, and this can be seen as an unstable noise floor in the spectrum. Windowing of the ADC output is a well-known solution to restore coherency and stable spectrum.However, windowing also modifies the amplitude o

In TI’s line of high-speed analog-to-digital converters (ADCs) with SNRBoost technology, output amplitude tends to deviate from its expected value when the applied input amplitude is small. This application note explains this phenomenon and the reasons it occurs.

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

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

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

This application report discusses the performance-related aspects of passive and active interfaces at the analog input of high-speed pipeline analog-to-digital converters (ADCs). The report simplifies the many possibilities into two main categories: passive and active interface circuits. The first section of the report gives an overview of equivalent models of buffered and unbuffered ADC input cir

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

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. The CDCE72010 clock synthesizer chip offers
