See also discussion on the AD forum: https://ez.analog.com/dds/f/q-a/107510/ad9912-ftw-lsb-always-zero We've tried to measure the frequency resolution of the AD9912 DDS, which when used with a 1 GHz SYSCLK should be 1 GHz / 2**48 = 3.55 uHz. We tried an ARTIQ Urukul-board and an AD dev-board and got the following results: In both cases the output … Continue reading AD9912 DDS frequency resolution?
Have been using this SMD heatsink for (among others) TO-263 voltage regulators, e.g. LT1963 and LT3015. https://www.fischerelektronik.de/pim/upload/fischerData/cadpdf/base/fk_244_13_d2_pak.pdf
These 'plain' footprints correspond to the "land-pattern" footprints created previously. No GND-pads or GND-vias in these.
