Industrial analogue I/O server targets process control and automation Lantronix’ xSenso Controller is the company’s newest member of xSenso analogue sensor networking family, designed specifically for use in rugged and harsh environments. The analogue and relay outputs provide the ability to take action by instantly controlling industrial processes and equipment based on the sensor readings and predefined thresholds to solve real-time problems. The unit is a compact, DIN-rail or wall mount solution that enables analogue sensors (voltage or current) to easily and transparently send real-time data to any node on the Internet or to a cloud-based application. In addition to its already robust feature set, the new xSenso can take action when a condition is met (e.g., temperature threshold, pressure level, etc.), triggering its internal relays or outputting voltage or current to control an event in real time. In an existing control system, the xSenso can also be placed in between the sensor and the controller to mirror the analogue data from its input to its output, while simultaneously presenting the data through a web browser to computers or mobile devices. The device operates in the -40° to +85°C temperature range and features secure authentication with up to 256 bit encryption, SSL, SSH. Lantronix www.Lantronix.com MEMS oscillators feature 100fs typical phase jitter and frequency margining capability Integrated Device Technology’s differential 4H MEMS oscillators feature a 100 femtosecond typical phase jitter performance and integrated frequency margining capability. The very low phase jitter and adaptable output frequency of these oscillators significantly reduce bit error rate (BER) in 10 gigabit Ethernet (10GbE) switches, routers, and other related networking equipment. The IDT 4H MEMS oscillators feature a differential LVDS / LVPECL output and the lowest phase jitter in their product class (100 fs at 1.875 to 20MHz and sub- 300 fs at 12kHz to 20 MHz), satisfying the low-jitter chipset requirements of high-performance networking applications. Integrated frequency margining capability enables customers to fine-tune the oscillator frequency during operation in the application by up to ±1000 ppm, minimizing BER and facilitating margin testing. Unlike competitive MEMS devices that only offer fixed frequencies, IDT’s device allows hundreds of offset frequencies that can be generated after the selection of any base frequency up to 625 MHz – even on final production systems. The IDT 4H MEMS oscillators are currently sampling to qualified customers and are available in standard 7.0x5.0, 5.0x3.2 and 3.2x2.5mm VFQFPN packages. Integrated Device Technology www.IDT.com 8-channel video capture on a mini PCI express card AMP’s AVC8000nano delivers 8-channel video capture on a mini PCI express card. Captured video can be scaled, cropped and positioned effortlessly, thanks to AVC8000nano’s intuitive software controls. In addition, captured video can be streamed continuously to system memory for immediate processing or local display or to disc storage. The card features 8 live NTSC/ PAL/RS170 video inputs, supports 8 D1 size capture at full frame rate, enables ultra-low latency multiple video capture and comes with comprehensive Windows and Linux support. Advanced Micro Peripherals www.ampltd.com Programmable hall switch extends flexibility of detection circuit designs Diodes Incorporated has introduced a programmable omnipolar Hall effect switch enabling designers to use the same contactless detection circuit in multiple applications or with different field strengths. The miniature and micropower AH1898 is suitable for numerous portable consumer applications including cell phones, tablets and cameras as well as a variety of domestic, office and industrial equipment. Able to detect both north and south magnetic fields, the AH1898 features a band-select pin, which allows device sensitivity to be changed to one of two predefined magnetic sensitivity ranges. In addition, it can also be used change the band on the fly, using an external logic source or microcontroller. The high sensitivity of the Hall sensor also means that it can support weaker, lower cost magnets and can be used at a greater distance from the magnet. The AH1898 Hall switch has been optimized for use across a 1.6 V to 3.6 V low- voltage supply range and employs a hibernating clocking system to minimize power consumption. With an average supply current of just 4.3 μA (typical) at 1.8 V, this micropower device helps to extend portable battery cell lifetime. To ensure high reliability in a broad range of applications, the AH1898 has been designed with an 8 kV ESD rating on supply and output pins. Circuit robustness is further raised by the AH1898’s chopper stabilized design, delivering superior temperature stability over the operating range from -40oC to +85oC, absolute minimum switch point drift, and enhanced immunity to RF noise and physical stress. The AH1898 is available in the miniature 0.8x0.8 mm CSP package, making it 12 times smaller than common TSOT-packaged alternatives. At the same time, the device’s simple 4-pin footprint and integration of pull-up resistors results in reduced external component counts and a simplification of PCB layouts.
