Because many things can affect transmission lines, EMI problems can occur. In order to reduce these problems, good PCB design is important and with some simple design rules, the PCB designer can minimize these problems. It is important to make prudent decisions during new circuit design, like the minimum number of layers. The easiest way to get a good, new design is to copy the recommended design from the TI evaluation modules (EVM). A good PCB layout starts with the circuit design. Do not postpone considerations about the layout. One of the most important aspects affecting the layout is the location of each functional block. Keep their devices and their traces together. PCB Considerations During the Circuit Design · What is the highest frequency and fastest rise time in the system? · What are the electrical specifications at the inputs and outputs of the sinks and sources? · Are there sensitive signals to route – for example, think about controlled impedance, ter...

What are the main benefits of rectangular connectors? When compared to circular connectors rectangular connectors are generally less expensive,have shorter lead times and are more easily customizable.Rectangular Connectors are also have better grounding system providing more protection against overvoltage and have a visual polarization for easy mating. They can also be easily keyed. Key advantages for using rectangular connectors over circular includes: 1. Off-the-self modules for easy custom designs for any application. 2. superior space efficiency. 3. more termination option-crimp,solder, screw terminal, others. 4. More locking options-single or double-lever or push button. 5. Ability to connect to other device such as PCB. 6. Greater contact Density Possible. 7. Greater cabling Flexibility- Top,Dual,side or angled cable entry. 8. Surface mount,Panel mount and cable to cable compability. 9.lower cost. 10.Better protection against over voltage. 11. easier Visual matin...
