Surface-mount ambient light sensing photodiode reduces power consumption
Design How-To  
2/2/2009   Post a comment
Vishay Intertechnology has introduced of a photodiode-based ambient light sensor in a compact 0805-sized surface-mount package, featuring a small 0.85 mm profile and simple 2-pin connection.

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.
