The development of the world's smallest 2016 size TCXO with two outputs of the same frequency

NIHON DEMPA KOGYO CO., LTD., represented by Hiroshi Takeuchi, has developed the world’s smallest(*1) (2.0 x 1.6 x 0.7mm) TCXO with two outputs of the same reference clock frequency. We plan to offer samples in October 2010 and start mass production in or after 2011.

Mobile information terminals such as smart phones equipped with short-distance wireless communication function such as Bluetooth or W-LAN in addition to the verbal communication function is becoming increasingly popular nowadays. Previously, a dedicated reference clock signal source was needed in order to equip the short-distance wireless communication function in addition to the verbal communication function. For this reason, the need for a TCXO that can provide reference clock signal to both of the two functions mentioned above has increased amidst the ambivalent two needs: miniaturization and multifunction. In order to meet these market needs, we have developed the world’s smallest TCXO with two outputs of the same frequency.

This TCXO can provide reference clock signal to both of the two functions via independent outputs. Also, its Enable/Disable function offers more efficient power management, leading to lower power consumption.

Previously, multiple reference clock sources were needed for the short-distance wireless communication function of mobile phones. But this TCXO alone can provide the reference clock signal to both of the two functions. This will help downsize the circuit boards in mobile information terminals. Moreover, the Enable/Disable function offers lower power consumption, longer battery life and reduced environmental load.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications. The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications. “We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner E

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs. The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs. Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these p


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference. The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection. The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
