Helpful app note from Silicon Labs for designing PCB for MCUs. Link here (PDF) The methods presented in this application note should be taken as suggestions which provide a good starting point in the design and layout of a PCB. It should be noted that one design rule does not necessarily fit all designs. It […]

App note: Transmission-line effects influence high-speed CMOS
Old app note from ONSEMI but still a good reference when designing with high speed CMOS devices. Link here (PDF) Unlike low-power, metal-gate CMOS, high-speed 54HC/74HC devices readily drive long cable runs and backplanes. While the family maintains CMOS’s traditional noise immunity, you must watch transmission-line effects in such applications.
App note: Guidelines on the effects of parasitic capacitance on clock accuracy due to board layout
Board design considerations like board thickness and layer stacking under a crystal when designing PCB for accurate clock crystals discuss in this app note from Maxim Integrated. Link here Crystal oscillator is widely used in RTC applications. Clock accuracy, one of the key parameters in real-time clocks, partly depends on the parasitic capacitance of the […]
App note: Board level application notes for DFN and QFN packages
Board mounting an DFN/QFN (Dual/Quad Flat-Pack No lead) application note from ON Semiconductor. Link here (PDF) The DFN/QFN platform offers a versatility which allows either a single or multiple semiconductor devices to be connected together within a leadless package. These guidelines include printed circuit board mounting pads, solder mask and stencil pattern and assembly process […]
App note: General layout guidelines for RF and mixed-signal PCBs
Rsdio came across an interesting app note from Maxim and shared it with us. These are some PCB layout guidelines for RF and mixed-signal designs. This application note provides guidelines and suggestions for RF printed-circuit board (PCB) design and layout, including some discussion of mixed-signal applications, such as digital, analog, and RF components on the […]
