Pin-in-Paste RF MoCA filter modules withstand a reflow temperature of 260°C Pulse Electronics has introduced RF MoCA (Multimedia over Cable Alliance) filter modules that are pin-in-paste compatible. Pin-in-paste manufacturing uses a reflow instead of a wave soldering process to apply solder to the components, saving time, increasing throughput, and reducing costs. These filters are compliant with MoCA 1.1 and 2.0 requirements and are qualified with leading MoCA silicon vendors. A filter module can be configured as a multiband diplexer /triplexer with CATV (Cable TV), satellite, and DOCSIS (Data Over Cable Service Interface Specification) frequencies with an optional built-in surge protection. They can withstand a maximum reflow temperature of 260°C and operate over an extended temperature range of -40° to +85°C. The pin-in-paste method (also called pin-in-hole, intrusive reflow, or through-hole reflow technology) is a process that allows through-hole components to be reflow-soldered instead of wave or hand soldered. Using solder reflow eliminates the cost of wave soldering equipment, saves manufacturing floor space, is a no-clean soldering process, reduces heat stress at the component level, is compatible with existing processes, and results in higher reliability at the printed circuit board level due to fewer soldering processes. The RF filters can also be inserted into the PCB using industry standard pick-and-place equipment. They are 100% tested. Pulse Electronics www.pulseelectronics.com Digital solid-state LED driver platform enables cost efficient solutions Chipmaker iWatt has launched a digital AC/DC solid state lighting (SSL) LED driver platform designed specifically to address the key issues of cost and lifetime in price-sensitive, non-dimmable, residential SSL bulb applications. The first device in this new platform is the iW3626, a single-stage driver with output power up to 10W for 60W-equivalent, non-dimmable LED bulbs. According to iWatt, the iW3626 allows SSL designers to reduce their bill of materials (BOM) cost as much as 20% compared to competitive solutions and is believed to be the first SSL LED driver to offer an on-chip, user-configurable power factor correction (PFC) to manage the trade-off between PFC and output current ripple. Additionally, an internal, configurable over-temperature protection (OTP) and derating function enables a predictable and reliable bulb operating life. This combination of features gives LED bulb manufacturers new options for lower-cost, higher-performance, non-dimmable SSL incandescent bulb replacement applications. The user-configurable PFC feature in the iW3626 allows designers to configure the PF strength from > 0.7 to > 0.9, enabling them to meet the various global mandates while effectively managing the trade-off between power factor and output ripple. The iW3626 is packaged in a standard, low-cost, 6-lead SOT23 package. iWatt www.iwatt.com Smart data concentrator module cuts nine months from developments Texas Instruments has launched a Smart Data Concentrator Evaluation Module (EVM) that can cut months from the development of a smart meter design. The TMDSDC-EVMAM335x is a highly integrated EVM based on TI’s Sitara AM335x ARM Cortex-A8 processors with advanced hardware and software that reduce development time by up to nine months while still supporting connectivity to more than 1,000 smart meters. The Smart Data Concentrator EVM expands the functionality of designs and enables quick connectivity to the smart grid. Developers can easily plug in different connectivity modules, including Sub-1GHz (LPRF), general packet radio service (GPRS), near field communication (NFC) and TI’s power line communication (PLC) system-on-module contains a C2000 Piccolo F28PLC83 and AFE031 analog front end for robust G3 and PRIME support. In addition, the data concentrator EVM offers an extensive open-source Linux software development kit that includes fully customizable, pre-written code. Developers can easily add functionality and features to data concentrator designs without the hassle of writing and tweaking code. It also includes resources such as PLC stacks (PLC-Lite, PRIME, G3, IEEE-P1901.2), network protocols and applications like DLMS/COSEM so developers can customize their products for multiple regional and global standards. Texas Instruments www.ti.com Compact dual mode Wi-Fi network controller targets home appliances Murata’s SN8200 series of compact low power certified Wi-Fi controller modules are capable of providing 2.4GHz 802.11b/g/n internet connectivity to a broad host of home appliances, industrial automation machines and healthcare equipment. The self-contained module uses Broadcom Corporation’s wireless internet connectivity for embedded devices (WICED) architecture to provide comprehensive firmware and software features including a built-in Wi-Fi security supplicant supporting WPA PSK and WPA2 PSK, TCP/IP network stack and a simple network interface card (SNIC) protocol that supports socket connections. Measuring just 30.5x19.4x2.9mm, the SN8200 module is certified to FCC, IC and ETSI wireless standards and is equipped with a STM32 ARM Cortex-M3, an on-board antenna and offers both UART or SPI connectivity to the host application. The ability to support sensor applications is also possible by using the module’s ADC, DAC, I2C and GPIO interfaces. The SN8200 can operate in either access point (AP) or station (STA) mode. An integrated web server available in AP mode makes target device setup and control extremely easy. Output power is typically +18 dBm when operating in 802.11b mode at 11 Mbps.
