TCXO offers tight stability in small package Product News 11/3/2003 Post a comment Responding to customer demand for small packaging and high performance in telecommunications applications, Connor-Winfield claims its new T501 is the industry's smallest temperature compensated crystal oscillator (TCXO) with a +/-4.6 ppm stability.
Synch clock generator compatible with existing platforms Product News 11/3/2003 Post a comment Connor-Winfield's new SCG102A synchronous clock generator is a pin-for-pin replacement for the Vectron FX102 product. The mixed-signal phase locked loop (PLL) generates LVPECL outputs from a fundamental frequency, low jitter, voltage controlled crystal oscillator. These are designed for line cards in telecommunications infrastructure equipment.
Wireless sensor nets demand trade-offs Product News 11/3/2003 Post a comment Wireless sensor networks represent an emerging technology that has great potential for widespread applications. These networks consist of a large number of simple nodes with limited power sources and functionality, but they offer far greater utility than the sum of those individual nodes.
Distributors shed failing components businesses Product News 11/1/2003 Post a comment As the technology recession continues to hammer at distributors' profits, more are being forced to re-evaluate their business models. Reptron Electronics is the latest to conclude that it might be better off without its electronic-components operations.
