I want to get two LPC800 mini kits. I have never used NXP chips and want to try out the effects. However, I found that there is no place to apply for samples on the NXP website and I couldn't find the...
What are the applications of ceramic capacitors and electrolytic capacitors? What parameters should be considered when selecting capacitors? How to choose a package? Are most SMD capacitors ceramic ca...
Now I need to design a 1175MHz oscillator. I looked at some PLL data sheets. Is the highest frequency of the phase detector the highest frequency of the crystal oscillator I need to use, and the VCO c...
