Hittite Introduces Two New Clock Generators with 3.3V Operation

Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has launched two exciting new SMT packaged clock generators, the HMC1033LP6GE and the HMC1035LP6GE. Ideal for a wide range of high performance Clock and Timing applications, these devices deliver best-in-class jitter and industry-leading phase noise floor.

The HMC1033LP6GE and the HMC1035LP6GE expand the company's growing Clocks & Timing portfolio by offering programmable frequency synthesis from 25 MHz to 2.5 GHz in both integer and fractional relationships to their reference clocks. The HMC1033LP6GE is ideal for clocking DSP, FPGA and high performance processors as well as physical layer devices, and operates from 25 MHz to 550 MHz. The HMC1035LP6GE is designed to meet the stringent requirements of high speed data converters (ADC/DAC) with excellent phase noise floor performance of -162 dBc/Hz, and operates from 25 MHz to 2.5 GHz. Both devices require only a single 3.3V supply rail and achieve up to 33% reduction in power consumption compared to previous solutions. The devices feature a flexible output buffer, which can be programmed via the serial programming interface (SPI) to support 12 different output amplitude settings including those for LVDS-compatible, and LVPECL signaling. A proprietary 'Exact Frequency Mode' of operation reduces frequency errors in fractional-N synthesis mode while maintaining excellent noise and spur performance.

Both products offer two modes of operation to trade off performance in favor of reduced power consumption. These two modes are defined as "Power Priority" and "Performance Priority" and may be selected via the SPI registers. In the "Power Priority" mode, the HMC1035LP6GE sources 173 mA typical current from the 3.3V supply with 2.5 GHz LVDS-compatible outputs, and in "Performance Priority" mode, the device achieves an integrated phase jitter performance of 100 fs RMS typical (12 kHz to 20 MHz integration bandwidth, 2.5GHz outputs), and improves interface Bit-Error-Rates (BER ) and eye diagram metrics. Both devices also produce an excellent 49-51% output duty cycle on their differential output.

The HMC1033LP6GE and the HMC1035LP6GE may be used to generate the sample clocks for high speed data converters (ADCs & DACs) in cellular infrastructure and fiber optic applications. With their very low phase noise floor, the clock generators improve the SNR (Signal-to-Noise-Ratio) performance of data converters by providing very clean sample and device clocks.

The HMC1033LP6GE and the HMC1035LP6GE are each assembled in 6 x 6 mm plastic leadless surface mount packages, and support operation over the -40 °C to +85 °C temperature range. Evaluation Kits with easy-to-use USB programming capability and GUI-based programming software to set the desired register configuration are available from Hittite.

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.
