Diagnosis over IP for communications modules Test system manufacturer Goepel electronic has enhanced the functionality of its series 61xx communications module: The company added the Diagnostic over IP (DoIP) capability to product’s feature set. The IP protocol implementation has taken place on the basis if ISO standard 13400 Part 2; both ISO/DIS 13400- 2:2010 and 2:2012 are supported. The interface cards automatically detect which DoIP version is used. During diagnosis execution, the interface module represents the external part of the test equipment and communicates with the device under test (DUT) through the internet protocol. As the DUT, typically automotive components are targeted. In this process, the IP address of the communications partner is transmitted automatically. The DoIP functionality is completely implemented in the G-API (Goepel electronic Application Programming Interface) software which is included with the 61xx communications module. This enables utilising the interface comfortably through any application. Comprehensive timing parameterising options allow tweaking the performance of the unit. The on-board software of the modules opens parameter handling for external sources, thereby facilitating and simplifying manual parameter entries by the user. The new feature is available for all hardware variants of the 61xx series. It makes use of the existing Ethernet interface which in the past has been used exclusively as a host interface. Goepel electronic www.goepel.com Laser multi-chip package offers 50W optical output A compact laser multi-chip package developed by Osram Opto Semiconductors can pack up to 20 blue laser chips in the PLPM4 450 module. The developers have managed to double the optical output of the individual chips, with the result that the new laser module now offers an overall output of 50 W. The result is that professional laser projectors can achieve a brightness level of more than 2000 lumen with one component. Instead of taking the laborious approach and constructing a light source from individual laser diodes, it is now possible to reduce the complexity of laser projectors. Osram Opto Semiconductors is strengthening its leading position in light sources for laser projectors with its blue PLPM4 450 multi-chip package. Osram developers are the first to adapt the ‘butterfly’ package for projection applications. The powerful laser module measures 25.5x35mm and accommodates four copper bars with up to five blue laser chips connected in series and operated at 2.3 A each. The multi-chip product offers a light output of 50 W from a typical electrical input of 165 W, with wavelengths of 440 to 460 nm. The package achieves an efficiency of 30%. Osram Opto Semiconductors www.osram-os.com Blackfin processors target power-constrained intelligent lighting Analog Devices, Inc. has introduced the ADSP-BF70x Blackfin processor family, which is a high-performance DSP series that delivers a class-leading 800 MMACS of processing power at less than 100 mW – double the performance or half the power of competing devices. The cost-effective eight-member Blackfin processor family includes up to 1 MB of internal SRAM, eliminating external memory in many applications, while a second configuration features an optional DDR memory interface. The combination of performance, power efficiency, integration and value allows designers to incorporate 16- and 32-bit processing in a range of new embedded vision use cases, including industrial imaging and building controls as well as portable and automotive audio. The ADSP-BF70x family offers designers unparalleled flexibility and functionality through an array of advanced connectivity options (including USB, SDIO, CAN, ePPI, SPORT, QuadSPI) while enabling power sensitive bus-powered applications and extending the life of battery-powered devices. The processor family’s low-power consumption, new 32-bit math and large on-chip SRAM also suits it to portable audio and automotive audio, where deterministic real-time processing is critical for high-fidelity sound. Analog Devices www.analog.com Digital potentiometers operate at 36V Supporting wide signal swings, Microchip’s DigiPots also feature high terminal/wiper current support and an extended temperature range. for industrial, automotive and audio applications. Microchip has expanded its 36V digital potentiometer (digipot) portfolio with two new volatile-configuration, I2C devices—the MCP45HV31 and MCP45HV51 (MCP45HV31-51). These are the first digipots to offer a 5 kΩ resistance with a specified operating voltage of 36V. They provide 10V to 36V analogue operation and 1.8V to 5.5V digital operation, for systems requiring wide signal swings or high power-supply voltages. The MCP45HV31-51 digipots support both 7-bit and 8-bit resistor configurations, and a high terminal/wiper current, including the ability to sink/source up to 25 mA on all terminal pins for driving larger loads. These features, combined with an extended temperature range of -40°C to +125°C, suit the MCP45HV31-51 for high-voltage and high-temperature applications, including those in the industrial, automotive and audio markets. The MCP45HV31’s 7-bit resistor network resolution enables 127 resistors and 128 taps, while the MCP45HV51’s 8-bit configuration supports 255 resistors and 256 taps. Additionally, both digipots provide RAB resistance options of 5, 10, 50 and 100 kΩ. Both devices also feature a 1 μA typical serial-interface inactive current, and a 2 MHz typical bandwidth operation (-3 dB) at the 5 kΩ resistance level.
