Design Note #119
Intra vascular ultrasound provides high quality image resolution of in vivo biological systems. This high speed multi-channel data acquisition system is capable of recording a high speed IVUS channel at data sampling rates up to 500 mega samples per second. Combining the disciplines of high speed analog amplifier design, filter design, analog to digital conversion design with low cost efficient FPGA design provides a cost effective data acquisition and data processing engine.
Giga sample per second analog to digital conversion functions, on the y data analysis functions, data formatting functions, low noise power conditioning, and overall system supervision functions are implemented on an Arria V FPGA. Operating at 10 gigabits per second, Analog Devices AD9680 communicates over a high speed multi-channel JESD204B data link to an Intel PSG Arria V FPGA. On the y data processing is performed within the Arria V FPGA, making the whole system extremely efficient, low power and low cost. Leveraging years of giga sample ADC design, this board set is OTEC’s third generation of high speed JESD204B data acquisition designs.
Impedance matched, low noise front end design is essential to clean high speed data acquisition. OTEC excels at the design of high performance, tuned analog amplifiers. Expertise in shielding design completes the low noise picture.
IVUS transducer excitation requires the generation of a clean, precisely timed high voltage pulse train. Transformer based, FPGA programmable pulse generation circuitry provides flexible transducer excitation.
