Power line protocols back multimedia use News & Analysis 10/11/1999 Post a comment To meet the requirements of almost all potential users, a home networking solution must deliver reliable network connectivity without new wiring. Only the truly adventurous technologist will struggle with the installation of cabling.
Inductorless design boosts outputs News & Analysis 10/5/1999 Post a comment Switched-capacitor charge pumps, which offer a size advantage over the equivalent inductor-based regulator, are popular for boosting the battery voltage in small handheld equipment.
Standards harden RF requirements News & Analysis 10/5/1999 Post a comment Changing standards for time-division-multiple-access cellular and personal communications systems are toughening RF requirements and making handset design more demanding.
DSL 'magic' opens Net to masses News & Analysis 10/5/1999 Post a comment Advances in digital subscriber line data communication are opening a new world of Internet access for home users, a world where they can speed to a remote server at data rates of 512 kbits/second to 8Mbits/s.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
