The addition of smarts to the accelerometer is a welcome feature! Having embedded DSP on chip will enable better performance and ease the host system's processing burden. I look forward to seeing them first hand. I like the low noise and daughter board approach as well. I had best get moving to sample some of these, don't want to fall behind.

Accelerometers with the ability to sense the direction of gestures like taps will make touch interfaces much more flexible--after all a tap could come from any of six directions. What I look forward to even more are intuitive gestures like lasso and flick, which I predict users will come to expect as much as tap-to-select.

Tap direction detection will take the application of accelerometer at something unpredicted features of personal electronics devices, lets see what comes the next. The package as well become so much tiny that it can be easily accommodated in any electronic product. Also the reduction in the sampling rate from 800Hz to 1.5Hz is something remarkable achievement for freescale.

LATEST ARCHIVED BROADCAST
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.
