TRACE AND SPACE WIDTH for Class 1

Preferred Pad Construction for Class 1 – 0.2/0.2 Surface Mount Technology Recommendations for one trace through 1mm BGA pads are as follows: • Via Pad diameter 0.50mm • Hole callout 0.25mm + 0/-0.25mm • Plane anti-pad 0.7mm • Trace width 0.2mm/Space width 0.2mm • These designs require 0.5‡ ounce outer layer copper foil construction for […]

CAN differential schematics for High Speed ISO 11898

CAN H and CAN

The ISO 11898−2 bus consists of the CAN_H (high) and CAN_L (low) data lines and a common ground signal. A 120  termination resistor is located at each end of the bus to minimize reflections and ringing on the waveforms

Motor opration

How to motor move one direction or both direction : The first is a low-side drive and the second is a high-side drive. The advantage to using the low-side drive is that a FET driver is not typically needed. Bidirectional control of a BDC motor requires a circuit called an H-bridge. The H-bridge, named for […]
