Hello,
does someone know how strong the electromagnetic emmissions of a homemade double-sided board (no ground plane) could be if there are some 74HC family, an 8051 cpu with quartzoszillator (6 MHz) and some sram and eeprom chips ?
The layout is not optimized, there is not an optimal return path for the bus signals. The power strips run parallel and there are decoupling capacitors.
I read that the 74HC family has EMI around 25 MHz decreasing to about 100 MHz because of its switching speed. In this region there could be some radio controlled toys in the neighbourhood and similar electronic devices.
Does someone know how strong this project could radiate ?
