USB Transceiver Supports Smartphone Applications

Texas Instruments has introduced the TUSB1310 Superspeed USB (USB 3.0) transceiver, which supports applications including surveillance cameras, smartphones, portable media players and more. The TUSB1310's Pipe3 and ULPI interfaces enable USB 3.0 functionality when used in conjunction with the integrated application processor digital cores. The 5Gbps USB 3.0 physical layer transceiver operates from a single crystal or external reference clock with selectable frequencies from 20, 25, 30 and 40MHz.

This allows the TUSB1310 to provide a cost-effective USB 3.0 solution with few external components and minimum implementation cost, according to Texas Instruments. The TUSB1310 supports many applications, including surveillance cameras, multimedia handsets, smartphones, digital still cameras, portable media players, personal navigation devices, audio docks, video IP phones, wireless IP phones and software-defined radios. Texas Instruments offers an expansive portfolio of Superspeed USB devices.

Devices include: the SN65LVPE502, a dual-channel USB 3.0 re-driver/equaliser; the TPD2EUSB30, a two-channel ESD solution for Superspeed USB 3.0 interface; and the TPS25xx series of USB power switches. Future offerings include peripherals, bridges, hubs and hosts. Receiver sensitivity of less than 50mV differential peak-to-peak for detecting weak signals is said to be twice as good as the specification requirement, allowing use of longer cables and easing board layout challenges. Flexible, integrated spread-spectrum clocking can reduce bill of materials cost by five per cent or more. Industry standard link layer interfaces (Pipe3 for USB 3.0 and ULPI for USB 2.0 compatibility) enable easy system integration to a variety of attached digital cores.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
