Some of themincluded the Trion T120 from Efinix, MachX02,MachX03, and Crosslink from LatticeSemiconductors.·The MachX02 was selected mainly because ofthe number of resources and documentation Initial steps02·CMOS Image sensor a) Uses Mosfets to convertaccumulated charge acrossphotodiode into a voltagesignal which can be used b) The voltage signal whichcorresponds to each pixel iscalled row by row c) There are two main types:Rolling shutter globalshutterPeripheral Components04·Some other components were needed in additionto the fpga such as: an oscillator, a clock buffer, anSPI to I2C, and voltage level translators ·Learned the difference between SPI and I2Cprotocols, their advantages, and disadvantages·Created schematics and footprints for resistorsand capacitors on Altium which were to be usedfor the peripheral components, the Sony imagesensor and the fpga. Implementation05The MachX02 is programmed by using theLattice Diamond softwareThe software has timing analysis and poweranalysis which could be used I initially ran into a few problems The first problem was a licensing issue whichtook some time to be resolved The second issue was regarding the referencedesign which was provided by LatticeThe code had multiple errors which Latticeneeded to be contacted before they wereresolved A documentation was also provided which wassupposed to outline how to the diamondsoftware should be used to run simulations forthe reference design provided. This washowever no the case Power analysis was able to provide anestimation regarding the power consumptionfor the given mode of operation Student InternOladayo OgunjimiAffiliationsWestern Undergraduate Summer ResearchInternship 2021ConversionBridge of SonySubLvds to MIPICSI-2 ObjectiveCreate a circuit board design to convert SonySublvds output data into MIPI CSI-2 protocol 01Faculty SupervisorProf. Jayshri Sabarinathan SybLvdsa) Tight electromagnetic coupling between thewires, which reduces the generation of EM noiseb) Reduces the vulnerability to EM noise c) Differential Voltageprovided by the company, along with areference design that can be used to simulatethe conversion between the two protocols
