Silicon Labs’ Si479xx Family Features SDR for Automotive Tuning
A new radio solution from Silicon Labs integrates RF front end and digital signal processing for automotive applications. The parts allow for a wide range of RF standards to be received and processed for automotive infotainment systems. The highly integrated solution requires less parts than a traditional front-end receiver would need, which in turn will reduce space requirements and overall costs. In addition, it will allow a single platform to be used for multiple applications.
Some of solution’s features include worldwide FM and AM band support, LW and SW support, weather-band support, two analog and two digital audio outputs, fully integrated automatic gain control (AGC), I/Q interfaces, and support for the Digital Radio Mondiale (DRM) standard.
UP Modular Boards Offer Extreme Computing Power
AAEON has released a second generation of its UP modular boards. The three boards comprising this latest release are configurable and about the size of a credit card. They include the UP Core Plus maker board along with the Net Plus and Vision Plus X docking boards. The UP Core Plus can be outfitted with Intel Atom x5/x7, Celeron, and Pentium processors. In addition, 2-, 4-, and 8-GB LPDDR4 is available for memory and 32, 64, and 128 GB is available for storage. The board also supports USB 3.0, features a display port, and has built in Wi-Fi and Bluetooth. The Net Plus docking board provides additional interface capabilities such as Gigabit LAN ports, a SATA interface, and a mPCIe slot. On the other hand, the Vision Plus X board offers solutions for powerful AI applications.
Bluetooth 5 Module Has Expanded Range
Laird’s new Bluetooth 5 module, the BL654 PA, includes PA/LNA circuitry to allow for further transmit range and better receive sensitivity. The module is powered by Nordic’s nRF52840 chipset, which also means it’s got a 32-bit Arm Cortex-M4 CPU running at 64 MHz. At +18-dBM output power, the module will consume about 88 mA. However, for lower power needs, the output power is adjustable down to −26 dBm. Furthermore, the module can include an integrated PCB antenna, or an IPEX connector can be used to allow for off-the-shelf antenna solutions. In terms of interfaces, 46 GPIOs are available that support UART, I2C, SPI, NFC, and analog-to-digital converters (ADCs).
Dialog Low-Power IoT SoC Eschews External CPU
A new chip from Dialog Semiconductor, dubbed the FC9000, targets battery-powered IoT applications. It contains an 802.11b/g/n radio, baseband processing with on board memory, a media access controller, and a host networking application processor. The features allow for full offloading capabilities so that no external CPU or networking processor is needed. The FC9000 enables up to a year of battery life by shutting down all possible elements within the chip when not transmitting. Many additional features are also included, such as a 16-bit sigma-delta analog-to-digital converter (ADC), a 12-bit successive-approximation-register (SAR) ADC, 16- to 22 -bit audio digital-to-analog converter (DAC), SPI and I2C interfaces, eMMC/SD for expanded memory, and multiplexed GPIO pins, to name a few. The part is available in a 7- × 7-mm, 60-pin QFN package and in modular form.
Keysight Distortion-Analysis App Characterizes 5G Modules
5G communications continues to push companies to build higher-performing products that can meet the demanding requirements of working with millimeter-wave technology. Keysight’s modulation distortion analysis application (S930705B) is an example of a recent advance that’s made to help with the 5G evolution. It’s available on the PNA-X Microwave Network Analyzer that offers high dynamic range and very low residual error vector magnitude (EVM). The application will enable 5G engineers to isolate and measure the performance of a device under wideband modulated signal stimuli. In addition, high-performance calibration techniques allow for repeatable and reliable measurements as well as “vector-corrected” measurements.
Next-Gen Network Analyzers Come in Three Form Factors
Keysight recently unveiled its latest generation of network analyzers in three different form factors. These are the E5080B ENA series bench-top boxes, the Streamline Series USB network analyzers, and the M980XA PXIe series of network analyzers. The new equipment gives RF engineers the flexibility of choosing smaller-form-factor measurement products or more portable devices. In addition, the analyzers are now coming with built-in pulse generators and modulators, spectrum-analysis capabilities, and time-domain analysis. This eliminates the need for additional equipment and allows users to completely characterize and test circuits with a single instrument. Reducing the amount of equipment needed also helps save space and costs needed for test setups.
High-Density Ethernet PHY Devices Handle 400 GbE
Microchip announced its new META-DX1 family of Ethernet physical-layer (PHY) devices are built for 1 Gigabit Ethernet up to 400 Gigabit Ethernet. In addition, flexible ethernet (FlexE), media-access-control security (MACsec) link encryption, and nanosecond timestamping accuracy capabilities are included. The new devices enable some of the fastest communications among Ethernet links while also providing secure communication links. FlexE capabilities allow Ethernet networks to be optimized for best use of network capacity. Three devices are part of the META-DX1 family—the PM6110, PM6108, and PM6104. Each offers different features, giving users the flexibility to choose the device that best suits their needs.
SiTime MEMS TCXOs Feature ±100-ppb Stability
Clocks are critical components within all communications systems. Depending on the systems deployed, specific accuracy requirements must be met. For example, frequency-shift-keying (FSK) systems may be able to tolerate clocks with ±50-ppm stability, whereas systems using quadrature amplitude modulation (QAM) would require tighter tolerances such as ±1ppm. SiTime’s new microelectromechanical-system (MEMS) temperature-compensated crystal oscillators (TCXOs) are capable of ±100-ppb stability. In addition, they have proved to be very resilient to external disturbances such as temperature deviations, supply-voltage variations, and mechanical disturbances. As a result, they’re well-suited for systems that require tight frequency stability, as well as those deployed in harsh operating conditions.
