IDT aims CMOS at quartz/MEMS News & Analysis 4/30/2010 Post a comment Integrated Device Technology announced its foray into CMOS oscillators which it claims replaces the need for quartz crystals without the need for MEMS.
The RCA phono plug: An outdated relic? Audio DesignLine Blog 4/21/2010 7 comments When it came to choosing the RCA phono plug as a standard for consumer audio (and video) applications, "cheap" and "simple" clearly won out over technical considerations.
Connector commoditization belies massive innovation Design How-To 4/18/2010 Post a comment From debatable audiophile psychoacoustics to the realizable goal of 40-Gbit/second mezzanine interfaces, the electromechanical innovations required to transfer charge efficiently and reliably are matched only by the questionable marketing necessary to maintain differentiation in an area that is at once both critical and commoditized.
Precision thin film resistors operate at up to 175°C Product News 4/13/2010 Post a comment Vishay Intertechnology has extended its MC AT series of professional thin film chip resistors to include devices in the 0402, 0603, 0805, and 1206 case sizes. The manufacturer also released a new precision version of the series with lower TCR and tolerances.
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.
