"Quad A" battery is a tickler Power DesignLine Blog 6/21/2008 Post a comment What's the future hold for the AAAA battery? It'll become more available but, to the critical eye, its technical justification is not yet clear.
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.
