Key Features - ADC14V155

The ADC14V155 employs a differential, pipelined architecture and operatesin single-ended or differential clock mode. Its superior dynamic performanceand linearity at high IF allows for the consolidation of signal paths,enabling the migration from a single carrier architecture to a multi-carrierapproach where a single ADC digitizes several carriers. The device'slow-jitter front-end allows the digitization of high frequency inputs up to450 MHz, providing flexibility in system frequency planning. The ADC14V155operates from a 3.3V supply and typically consumes 951 mW. It offers apower-down feature to reduce power consumption to 15 mW, while a separate 1.8Vsupply for the digital interface allows low-power operation with reduced noise.The ADC14V155 is supplied in a 48-pin LLP package.
