$2 Chips Deliver High Resolution Audio to consumer applications

XMOS Ltd. the leader in intelligent multicore microcontrollers, has today announced the launch and first customer shipments, of its new xCORE-AUDIOTM processor family. Delivering bit-perfect audio across a rich set of audiophile and professional interfaces, xCORE-AUDIO processors are designed to meet the demands of both high-resolution consumer audio and complex multichannel professional audio applications. Two product lines are announced:
  •     xCORE-AUDIO Hi-Res, targeting the emerging market for stereo high resolution USB headphone amplifiers, DACs and AVR systems;
  •     xCORE-AUDIO Live, which supports prosumer and professional audio applications including DJ kits, mixing, audio content creation and conferencing.
The xCORE-AUDIO is built on the performance leading XMOS xCORE-200TM multicore microcontroller processor technology, with the stereo Hi-Res-2 sampling now to first customers, and will cost less than $2.00 in high volume. The first xCORE-AUDIO Live products will follow in April 2015.

Announcing the new product families, Nigel Toon CEO of XMOS said, "Our xCORE-AUDIO processors deliver outstanding audio performance. The demand for high-resolution audio content for consumption on the move, and the complexities of creating the same content in the studio and concert hall, are well served by our class-leading USB 2.0 and networked audio solutions. By selecting output formats from our rich audio I/O libraries, and using multicore power to implement complex DSP functions, XMOS delivers professional audio solutions at consumer prices."

XMOS has sampled lead customers with xCORE-AUDIO Hi-Res chips and development boards.

"With XMOS already powering our award-winning family of audiophile Blu-ray players and headphone amplifiers, we are very excited to be one of the first customers to receive the new xCORE-AUDIO Hi-Res devices," said Jason Liao, CTO and VP Product Development of Oppo Digital, Inc. "The unmatched combination of bit-perfect USB audio, advanced output formats, sample rates of up to 384kHz and beyond, marks xCORE-AUDIO Hi-Res as an outstanding contribution to the high-resolution audio market"

"The xCORE-AUDIO family of processors continues XMOS' tradition of innovation in the USB audio space," commented Richard Hollinshead, Director of Engineering for Meridian Audio. "Bit-perfect, asynchronous USB audio results in an outstanding listening experience. xCORE-AUDIO will deliver that audiophile experience into consumer markets, and we welcome these additions to the XMOS product family."

Samples of xCORE-AUDIO Hi-Res 2 support:
  •     USB 2.0 (Full-speed and High-speed), USB Audio Class 1.0, USB Audio Class 2.0, USB Firmware Upgrade (DFU) 1.1.
  •     I2S, DSD and SPDIF output formats.
  •     44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz sample rates.
  •     Broad range of host platforms supported including:
    •         Made For iPhone support including role switch and External Accessory Framework.
    •         Android device, Windows PC, and Apple OSX support
  •     Small-footprint 64pin TQFP packages and 128pin TQFP packages available.

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.
