Controller Enables DigRF Implementation Into ICs

Synopsys is offering the configurable Designware MIPI 4G DigRF Master Controller, which is compliant to the MIPI DigRF v4 1.00 specification and enables designers to reliably implement the standard. By complementing its current silicon-proven Designware MIPI 3G DigRF Controller and PHY IP, Synopsys completes its IP portfolio for the MIPI DigRF v3 and v4 standards. In addition, Synopsys is developing the Designware M-PHY(SM) - the physical layer for the MIPI DigRF v4 interface - in parallel with the ratification of the specification.

A single-vendor solution enables designers to lower the risk and cost of integrating the DigRF interfaces into baseband ICs (BBICs) and application processors, while speeding time to market of advanced LTE and Mobile WiMAX system-on-chips (SoCs). MIPI Alliance's DigRF v4 is the latest generation of the standard that defines the interface between RF transceiver ICs (RFIC) and BBICs and addresses the increased data-throughput requirements for mobile terminals targeting 4G standard air interfaces such as LTE and mWiMAX. The DigRF v4 specification also supports existing 3GPP standards such as 2.5G and 3.5G.

The low-power, area-efficient Designware 4G DigRF Master Controller implements the features defined for the protocol and PHY adaptation layers of the DigRF v4 rev 1.00 specification. It has also verified interoperability with RFIC devices currently available on the market. Configurability of the IP RTL provides flexibility for system-specific implementations, such as number of lanes, sublinks and diversity, while protocol-specific attributes including IQ sample size, frame scheduling and handling of timing-critical signals are software programmable.

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.
