In the EMC design of RS-485 ports, we need to focus on three factors: electrostatic discharge (ESD), electrical fast transients (EFT) and surge. The International Electrotechnical Commission (IEC) spe
As shown in Figure 1, the input signal VIN is given by the DSP chip. In Figure 1, R3 and C1 as well as R2 and C3 form a two-order low-pass filter. What is the principle of this filtering? It is easy t
When I used AD to export gerber today, it prompted "The Film is too small for this PCB"
Because I failed to import DXF files using AD before, I suspect that the DXF has actually been imported, but it
Active phased array radar has strict requirements on the phase consistency of TR components. The test of pulse signal phase is relatively complicated. This paper proposes three test methods for the ph
Infineon aims to create advanced audio products. While adhering to the principle of quality first, it also takes into account user experience during development to ensure that it can bring customers a
