IDT Introduces World’s First Piezoelectric MEMS Oscillators for High-performance Applications

Integrated Device Technology, Inc. (IDT®; NASDAQ: IDTI), the Analog and Digital Company™ delivering essential mixed-signal semiconductor solutions, today announced the world’s first CrystalFree™ piezoelectric MEMS (pMEMS™) LVDS / LVPECL oscillators for high-performance communications, consumer, cloud, and industrial applications. IDT’s new oscillators operate with substantially less than one picosecond of phase jitter in compact industry-standard packaging, making them an ideal replacement for traditional six-pin crystal oscillators (XOs).

The IDT 4M series high-performance LVDS / LVPECL oscillators leverage IDT’s patented CrystalFree pMEMS resonator technology, enabling IDT to rapidly factory-program the desired output frequency without the need to fine-tune expensive crystals. In addition, because the nominal resonator frequency of pMEMS is much higher than quartz crystal, 4M oscillators are able to achieve higher frequencies at lower cost without sacrificing critical performance. The 4M series is the first of a broad portfolio of MEMS-based devices from IDT that will provide customers with convenient, accurate, low-jitter timing references.

“As the leader in timing, our customers have been waiting for IDT’s pMEMS technology to expand into high-performance applications such as communications – a significant segment of the $4B frequency control market,” said Fred Zust, vice president and general manager of the Timing and Synchronization Division at IDT. “IDT’s patented pMEMS resonator technology combines the strong electromechanical coupling of the piezoelectric material with the stability and low damping of single-crystal silicon, allowing us to create convenient and cost-effective XO replacements with unparalleled performance and reliability. These products complement our award-winning solid-state oscillators to offer a comprehensive frequency control portfolio to replace quartz-based devices in a growing number of market segments.”

The IDT 4M oscillators operate with ±50 ppm frequency accuracy over the wide industrial temperature range of -40°C to 85°C. The devices support low-voltage differential signaling (LVDS) and low-voltage positive emitter-coupled logic (LVPECL) at frequencies of up to 625 MHz, meeting the stringent requirements of most communications, networking and high-performance computing applications. In addition to 7.0 x 5.0 mm (7050) sizes, IDT’s pMEMS oscillators are available in small 5.0 x 3.2 mm (5032) standard plastic packages to save cost and minimize the application footprint in densely populated enclosures. By design, they are pin-to-pin compatible with traditional XOs, making them an ideal upgrade replacement solution.

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.
