  • The veteran’s answer about Crystal Oscillator (Part one)

    Someone who has just started to join in Electronic Industry,they often faced the questions about Crystal Oscillator,even they have researched a lot of resources from refernce books or internet,but many of them are still in confusion. Today I share with you some typical questions and answers from the veteran electronic engineer. What’s the fonction of Crystal Oscillator? The main fonction is providing a clock signal for the whole system. For example,the run model of CPU is step by step,every step defined an instruction that base on Crystal Oscillator. What’s the relation between Crystal Oscillator and timing sequence? Timing sequence is counted on the clock’s order,and the clock is generated by a Crystal Oscillator. Why we often set some different Crystal Oscillator on the same PCB? Evey different CPU or Chip has different frequencies,they need matched Crystal Oscillator to run. For example,USB1.1 needs 48MHz clock to be divided, so 12MHz crystal......

  • The veteran’s answer about Crystal Oscillator (Part two)

    USB1.1 needs 48MHz clock to be divided, so 12MHz crystal oscillator is required, and the frequency is 4 times that of 48MHz. Why don’t choose 48MHz Crystal Oscillator directly? Because high frequency crystal oscillator is easy to be affected by peripheral circuits or affect peripheral circuits. Most of the time,we get high frequency by using low frequency crystal oscillator with second harmonic generation. But it’s not absolute,many circuits is often used a crystal oscillator of 50M or more. That’s a key point that we need a special attention when we do PCB layout.   Why we use 32.768KHz crystal oscillator when the RTC clock needs a more accurate 1S (1 second)? Because all digital circuits are expressed by binary system,32768 is 1000000000000000 in binary system. So as long as we detect the highest bit changes, we will know that 1 second, don’t need to check every bit, the circuit is......

Why does PCB need to do impedance control ?

Today, let's talk about why the PCB board needs to do impedance control and what is the meaning of impedance control for the PCB board  1.Why does PCB need to do impedance control ? The pcb board impedance refers to the resistance and the parameters of the reactance, which hinder the AC. Impedance control processing is essential in the production of PCB  industry. Reasons are as follows: 1)As we all know,the PCB need to do mounting of electronic components, So,we should consider the conductive performance and signal transmission performance after mounting,So it will require the lower the impedance, the better. 2)In the production process, PCB boards are subjected to manufacturing steps such as copper plating , electroplating tin ,and soldering. In the meanwhile,the materials used in these process steps must be  low resistivity enough to ensure that the overall impedance control of the PCB board is low and meets product quality requirements. 3)There are various signal transmissions in the conductor layer of the PCB board,when you want to increase signal transmission speed rate,...
