Driving High-Speed A/D Converters for High Performance

The ADC14DS105 is a dual 14-bit 105 MHz converter with serial LVDS outputs. It has an input bandwidth of 1 GHz and a low power of 1W total. The ADC14DS105 is useful in many applications. Its dual channels are handy for I and Q channel processing, which is useful in the design of communication systems and basestations. This paper discusses design implementation using the ADC14DS105, focusing on how to provide input signals and clock to the converter and on reading data from its serial interface. Lastly, the unique output drive details are reviewed.
