A Quad 12bit 1.6 GSps ADC with Synchronization feature for use in Multi-element Systems

Multi-element phased array radar systems are being developed with greater number of channels to achieve more flexibility, speed and precision. The ability to digitize each channel brings the advantages of digital beamforming.This paper describes a new quad Analog to Digital Converter (ADC) which provides a daisy chain method of synchronizing multiple ADCs, an efficient serial interface and internal sample time delay adjustability. These features are useful for phased array systems.Some initial results from the ADC are presented.
