In addition to the International Telecommunications Union (discussed in part 1 of this FAQ series), there are several organizations that define and regulate acceptable levels of conducted and radiated emissions from electronic devices. These various agencies have developed numerous standards generally based on the operational environment of the specific device. Effectively managing EMI is a […]

Ultra-low-jitter clock oscillators target high-frequency DSPs in optical apps
Raltron has launched an ultra-low-jitter clock oscillator family suitable for high-frequency digital signal processors (DSPs) in optical applications. The CL2520 LVDS clock oscillator series is designed to support optical modules commonly used in networking and data center applications. These include quad small form-factor pluggable (QSFP), octal small form-factor pluggable (OSFP), and C form-factor pluggable 2 […]
EMI, EMC, EMS, and the ITU
Controlling electromagnetic interference (EMI), also referred to as radio frequency interference (RFI), and minimizing electromagnetic susceptibility (EMS) are two important aspects of maintaining electromagnetic compatibility (EMC). Ensuring electromagnetic compatibility at a specified level and under specific operating conditions is a common demand in the design of almost all electronic systems. Common terms used when discussing […]
