ADC Evaluation Platform
Intersil offers an ADC Evaluation platform which can be used
to evaluate any of the KADxxxxx ADC family. The platform
consists of a FPGA based data capture motherboard and a
family of ADC daughtercards. This USB based platform
allows a user to quickly evaluate the ADC’s performance at a
user’s specific application frequency requirements. More

Layout Considerations
Split Ground and Power Planes
Data converters operating at high sampling frequencies
require extra care in PC board layout. Many complex board
designs benefit from isolating the analog and digital
sections. Analog supply and ground planes should be laid
out under signal and clock inputs. Locate the digital planes
under outputs and logic pins. Grounds should be joined
under the chip.
