78M6613 Printed Circuit Board Layout Guidelines

By: Ken Harada

Abstract: The highly integrated 78M6613 system-on-chip (SoC) reduces the complexity of the solution's printed-circuit-board (PCB) layout design. However, some design issues require consideration for optimum measurement accuracy and reliability. The article discusses PCB stackup, crystal oscillator components, LINE voltage resistor networks, shunt-current sensors, two-shunt current-sensor topology, V3P3 decoupling capacitors, in-circuit emulator connectors, and the system communication interface. It specifically does not discuss creepage and clearance. Refer to the discussion of creepage and clearance in UL 60950-1.
