High Speed Automotive LIDAR System, Self Driving Motion Control

LIDAR is all about measurement of the speed of light. OTEC’s two board set measures the speed of light with precision to spare. This translates into unsurpassed low-noise spatial resolution. Implemented as a two board set, OTEC’s precision multi-channel infrared laser light detection system is assembled on a specially designed ultra-quite, shielded circuit board assembly. Multiple high speed transconductance ampliers interface with a photodetector diode array. That array is the source which provides highly sensitive light impulse data to the giga sample analog to digital conversion board residing below.

Dual channel 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 10 FPGA. Operating at 32 gigabits per second, Analog Devices AD9680 communicates over a high speed multi-channel JESD204B data link to an Intel PSG Arria 10 FPGA. On the y data processing is performed within the Arria 10 FPGA, making the whole system extremely efcient, low power and low cost. Leveraging years of giga sample ADC design, this board set is OTEC’s fourth generation of high speed JESD204B designs.

OTEC has unmatched experience with low noise analog design, analog filter design, multi lane JEDS204B system design, custom FPGA algorithm design, and board level design/layout and rapid prototype construction.
