Phyworks has announced a fully 10GBASE-LRM compliant serial retiming receiver with Electronic Dispersion Compensation (EDC). Manufactured on a CMOS process, this second-generation EDC chip offers a powerful equaliser. The PHY2060 enables upgrade of X2 and XFP optical modules and SFP+ based line cards to true 10Gbps LRM operation.Combining clock data recovery (CDR) and a fully automatic EDC circuit, the integrated PHY2060 simplifies optical module design. The chip’s internal algorithms remove the need for complex microcontroller support. The IC is in a miniature 36-pin, 5mm x 5mm flip-chip BGA packaging. To simplify product evaluation and qualification the PHY2060 also includes a PRBS generator and a BER detector, enabling end-to-end link testing. On boot-up the device automatically selects between the chip’s 2-wire or serial peripheral interfaces. Phyworks’ proprietary, fully LRM compliant EDC technology is dedicated for overcoming modal dispersion in multimode fibre LAN infrastructure and achieving reliable 300m link lengths. PHY2060 samples and an evaluation board are available now. The chip is priced at $25 USD in volume.
 

Luminary Micro announced communications modules and reference design kits for Ethernet-enabled display applications and serial-to-Ethernet communications applications. Based on Luminary Micro’s real-time Stellaris microcontrollers, the communications modules and accompanying reference design kits provide OEMs with a production-ready solution to integrate high performance communications into their end products. The compact networked Intelligent Display Module (MDL-IDM) offers a complete graphical touch-screen user interface solution for control, automation, and instrumentation applications.

 Featuring a 2.8” QVGA 16-bit color LCD resistive touch panel display and Power-over-Ethernet (PoE) capability, the Stellaris MDL-IDM offers a method to produce intelligent terminals that can be simultaneously powered and network-connected by a single CAT5 Ethernet cable. Alternatively, the module can be powered with a standard 24 V DC power supply or through 5 V DC terminals. The MDL-IDM module also features additional serial connectivity options for easy implementation as a Human Machine Interface (HMI) touch display panel in an embedded control device. Built upon the high performance Stellaris LM3S6918 MCU with 256K of single-cycle Flash memory and 64K of single-cycle SRAM, the Intelligent Display Module also includes an additional 128K of display memory, an SD Card interface, an audio transducer, a relay output, and four analog measurement inputs.

 Software for the Intelligent Display Module includes the Stellaris Graphics Library and Stellaris Peripheral Driver Library. The libraries provide an easy C/C++ applications programming interface that generates graphical elements for the IDM and that controls the peripherals found on the LM3S6918 MCU, respectively. The Stellaris Graphics Library supports widgets (push buttons, check boxes, radio buttons, text or image canvas elements), and basic graphical primitives (lines, circles, rectangles, and text rendering). The software support also includes a board support package that provides software drivers for the touch screen, the SD Card interface, the relay output, the sound capability, and the analog inputs. The Reference Design Kit for the Intelligent Display Module includes an Ethernet cable, wall power supply, and CD containing all the module design information, including schematics, BOM, Gerber files, software source code, and documentation. All of the module design information is openly available, NRE- and royalty-free, for use and modification on any Stellaris-based design.

 Serial-to-Ethernet Module (MDL-S2E) and Reference Design Kit (RDK-S2E)

The tiny-footprint Luminary Micro Stellaris Serial-to-Ethernet Module (MDL-S2E) offers a complete, ready-to-implement solution designed to add web connectivity to any serial device. The most common application for the MDL-S2E is for augmenting legacy products that only contain a serial port for a configuration or control interface. Many newer computers, especially laptop computers, do not have serial ports. In addition, a serial connection is limited by cable length (typically 10 m). Simply installing a Stellaris Serial-to-Ethernet Module into the legacy serial design provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and freedom from the 10-meter maximum cable length limitation for serial connections.

 The MDL-S2E is a serial-to-Ethernet converter available with a highly integrated ARM Cortex-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the Stellaris microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHY on-chip. Preprogrammed software included in the module supports IP configuration with static IP address or DHCP; a Telnet server for access to serial port; a web server for module configuration; UDP responder for device discovery; a Telnet client for Ethernet-based serial port extender; and SSH server for secure communications. The Reference Design Kit for the Serial-to-Ethernet Module includes a retractable Ethernet cable, USB cable for power from a PC, DB9 serial cable, an adaptor board containing the DB9 serial connector, and CD containing all the module design information, including schematics, BOM, Gerber files, software source code, and documentation. All of the module design information is openly available, NRE- and royalty-free, for use and modification on any Stellaris-based design.

 Available module design information includes schematics, BOM, Gerber files, software source code, and documentation. Luminary Micro also provides a Reference Design Kit version of each module that contains all components and cables for out-of-the-box use in development environments.

Seoul Semiconductor announced the development of the ultra bright LED, Z-Power P7 Series. The Z-Power P7 Series, which the company started producing in volume quantities today, delivers brightness of 900 lumens at 10 watt. The 10W P7 single LED package produces luminous flux of 900 lumens. The Z-Power P7 Series has an efficacy of 90 lumens per watt from a single package, which is eight times higher than incandescent lamps. The Z-power P7 Series overwhelms incandescent lamps in terms of energy efficiency, a significant development that signals LED’s penetration into the general lighting market is just around the corner. The series is able to focus light in a specific direction based on the users’ need. As a result, there is little loss of light generated from the source. Not only is efficacy of the Z-Power P7 Series nearly 1.5 times higher than general light bulbs, but when the light loss is considered, the actual luminous efficacy of the Z-Power P7 Series is 2.5 times higher compared to a general light bulb of approximately the same luminous flux. The Series can be applied in many fields such as general residential lighting, streetlights, a variety of task lights, high-end flashlights for military, police or rugged use, and landscape lighting requiring extremely bright light.
