Main St., Orange, CA 92868 Tel. 714-639-7810 | Fax 714-997-1256 www.STATEK.com Frequency-programmable narrow-band transmitter RF module designer and manufacturer Radiometrix has a range of flexible, frequency programmable, RF power adjustable, radios. The NTX2B transmitter offers true Narrow Band FM (NBFM) performance and is available on user/factory programmable custom frequencies between 425 MHz and 470 MHz. The transmitter offers greater stability and improved performance due to its VCTCXO reference. The NTX2B provides users with the ability to dynamically re-program the module via a microcontroller UART to other channel frequencies in the band or store new frequency/power settings on EEPROM. The standard NTX2B version is a 10 mW 25 kHz Narrow band Transmitter with data rates up to 10 kbps and is available on 434.075 MHz, 434.650 MHz European SRD frequencies and 25 mW on 458.700 MHz for the UK. The NTX2B is also available with 12.5 kHz or 20 kHz channel spacing for licensed US FCC Part 90 or legacy European Telemetry/Telecommand bands. The NTX2B features an internal LDO voltage regulator which enables the transmitter to be operated down to 2.9V and up to 15V voltage supply at a nominal current consumption of 18 mA and less than 3 μA in power-down mode, which can be enabled within 5 ms. Radiometrix www.radiometrix.com Semtech adds LoRa RF to Wi-SUN for meter reading Semtech is cooperating with Freescale and Nissin to develop a complete solution featuring the Freescale Kinetis MCU and Nissin Wi-SUN software stack, for the Japanese market; Semtech has announced it has joined with other members of the Wi-SUN Alliance to produce a radio frequency (RF) development platform targeting advanced metering infrastructure (AMI) and industrial applications. The development platform includes Semtech’s SX1276 Wi-SUN compliant RF transceiver that features its long-range LoRa technology, combined with a Kinetis microcontroller (MCU) from Freescale. The Wi-SUN ready software stack is provided by Nissin, a contributor member of Wi-SUN. The Semtech SX1276, a Wi-SUN ready, LoRa-based transceiver with a 168 dbB link budget for maximum range, constitutes the wireless portion of the solution. Semtech www.semtech.com Automotive audio bus boosts digital audio quality In what will be regarded as a challenge to incumbent technologies such as MOST, and to the trend for “everything-Ethernet” - in this case, Ethernet AVB - Analog Devices’ AD2410 transceiver uses the new Automotive Audio Bus (A²B) to deliver 50 Mbps bandwidth while reducing audio system cost, weight, and design complexity. This device embodies a digital audio bus technology capable of distributing audio and control data together with clock and power over a single, unshielded twisted-pair (UTP) wire. The AD2410 transceiver is the first in a family of devices that enables ADI’s new Automotive Audio Bus (A²B), which significantly reduces the weight of existing cable harnesses, while delivering high-fidelity audio. The AD2410 transceiver also eliminates the need for expensive microcontrollers with large memories that are required in existing digital bus architectures. The AD2410 is a low-cost audio transceiver that provides 50 Mbps of data bandwidth and support for up to 32 discrete upstream and downstream audio channels. All standard audio sampling rates are supported as is daisy-chaining of multiple AD2410 slave devices to a single master. Unlike existing digital bus architectures, system delay is fully deterministic at all slave nodes.
