Power LED emitter provides high brightness, high moisture sensitivity
Product News  
3/1/2007   Post a comment
Avago Technologies has released a low-profile, 3-watt high-power white LED emitter for a variety of solid-state lighting applications.

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.
