Adapt standard tests to non-standard devices: Automotive qualification of a MEMS-based sensor system
Design How-To  
12/11/2008   Post a comment
AEC-Q100 does not address MEMS and unencapsulated devices. This is where the engineer designing the test plan must get creative in seeking a solid physics-of-failure-based test regime. The authors prove that an exposed humidity sensor can survive a lifetime of humidity-temperature and bias, tests particularly severe for the sensor and its exposed wire bonds.

Ipetronik : Automotive data loggers transmit data to PC
Product News  
12/1/2008   Post a comment
With XCP Service, Ipetronik provides convenient online transmission of measurement data from its automotive M-LOG and S-LOG data loggers to a PC.

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.
