Interface Technology Fits Wireless Infrastructure

NXP Semiconductors has launched CGVxpress as an extension to its high-speed data-converter technology portfolio, and the next generation of the CGV high-speed serial interface announced in 2009. The CGVxpress will be used in future NXP ADC and DAC product ranges. The first demonstration of CGVxpress will occur at the IEEE International Microwave Symposium, held on 7-9 June 2011 in Baltimore, Maryland. NXP will showcase a 4.5Gbps CGVxpress transmitter interworking with an industry-standard FPGA over a 20cm differential data lane.

CGVxpress (Convertisseur Grande Vitesse or High Speed Converter) interface technology is suited for: wireless infrastructure, industrial, scientific, medical, and aerospace and defence applications, where high bandwidth, sample accurate lane synchronisation and deterministic latency are critically technical requirements. The CGVxpress feature set also includes support for Multi-Device Synchronisation. MDS solves tough system synchronisation and latency challenges in many digital communications-system applications, including LTE and LTE-Advanced MIMO radio base-stations. The CGV interface currently appears on several products in NXP's high-speed ADC and DAC product line - including the ADC1413D and DA1408D product ranges.

Features: reduces the number of interconnect signals between the data converters and logic devices; solves a major base-station system design challenge by synchronously bonding multiple data lanes with sample-level accuracy; CGVxpress facilitates significantly reduced PCB design and manufacturing complexity, impacting both NRE costs and marginal production costs; systems can often be implemented using fewer PCB layers as compared to traditional parallel interfaces.

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.
