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
