Basic questions When do you need to start caring about matched net lengths etc? 100Mz to 200Mz is a good handwavy guide (but not necessarily!) How much propagation delay is added by PCB traces? 1nS of propagation delay is added to a signal for every 150mm / 6″ of PCB trace. Dielectric constant Varies between […]

Traditional electronic design methods are encountering a new problem when using newer electronic devices that provide a clock based data input or output (for example a MMC or SD memory card via a SPI communication bus). As semiconductor devices have become faster and faster in recent years they have become much more susceptible to issues […]
