Bi-color LEDs go surface mount Product News 3/24/2004 Post a comment Elma Electronic is providing its line of bi-color LEDs in surface-mount packages, which can help customers reduce costs during the manufacturing process by eliminating the need to drill special holes or use a separate soldering process for through-hole devices.
Sensors handle tough auto environments Product News 3/22/2004 Post a comment TT electronics OPTEK Technology has developed two new sensors that can withstand harsh automotive environments. The new OPB350 non-contact fluid sensor detects virtually any liquid including water, oil, gasoline, coolant or hydraulic fluids for braking or power steering systems, while the new Hall Effect sensor provides position sensing of rotary shafts.
Image sensor packs in the features Product News 3/22/2004 Post a comment Hamamatsu Corp. offers a new CMOS linear image sensor that provides high sensitivity, low dark current and low noise, which makes it suitable for image input applications such as position detection and image reading. In addition, the new S9226 features a built-in timing generator and an advanced signal processing circuit in a small package.
Bookham expands optical component assembly to China News & Analysis 3/17/2004 Post a comment Bookham Technology plc is to re-equip the test and assembly facility in Shenzhen, China, that it acquired through the acquisition of New Focus Inc. and start supplying transmitter and receiver optical assemblies, simple amplifiers, connectors and fiber assemblies from the facility.
Sensing solution detects ultra-low light levels Product News 3/15/2004 Post a comment Texas Advanced Optoelectronic Solutions Inc. (TAOS) says its new light-to-frequency converter is capable of sensing ultra-low light levels undetectable by most silicon-based sensors. This new sensing solution combines enhanced sensitivity with low dark-signal circuitry (typical dark frequency of 0.1 Hz) that extends the performance range down to very low light levels of 0.00002 Lux.
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.
