Analog Devices announced its latest generation of reinforced isolated power converters, allowing systems to meet EN 55022/CISPR 22 Class B Electromagnetic Interference (EMI) standard requirements. The ADuM5020/6020 and ADuM5028/6028 series eliminate the need for costly EMI mitigation techniques at the application level and simplify the EMI certification process, reducing design cost and time.

Furthermore, use of these devices can achieve emissions targets on a two-layer PCB, which reduces the solution size by as much as 70 percent and decreases material cost by 30 percent compared to a four-layer board.

Microsemi launched its SA.45s Commercial Space Chip Scale Atomic Clock (CSAC), the first commercially available radiation-tolerant CSAC. Ideally suited for low Earth orbit (LEO) applications, the device provides the accuracy and stability of atomic clock technology while achieving advances in reduced size, weight and power consumption.

As a stand-alone atomic clock with a 10 MHz CMOS-compatible output, the CSAC is a timing module providing short-term stability (Allan Deviation) and frequency stability across the operating temperature. A standard CMOS-level RS-232 serial interface is built into the device, which is used to control and calibrate the unit and provides a comprehensive set of status monitors. The interface also is used to set and read the CSAC’s precise internal time-of-day clock.

Additional technical specifications are available on Microsemi’s website.

Pasternack Skew Matched Cable Pairs

Pasternack released a line of skew matched cables for use in high-speed digital tests of 10 Gbps to 28 Gbps, including differential signals, bit-error-rate testing and eye diagrams. The line is madeup of three models that have 1 ps delay match. These cables provide VSWR of 1.4:1 and are 100 percent tested for skew match. They also include polarity indicators and restraint bands to keep themselves paired up.

These delay matched cables have a frequency range of DC to 40 GHz, covering two channels with 50 Ohms nominal impedance. They are made of micro porous PTFE cable dielectric and feature triple-shielded outer conductors, 2.92mm male connectors and finger-grip coupling nuts. They are ideal for networking, semiconductor test and supercomputing industries where skew match is important.

Synopsys announced that it has been enhancing its design tools with artificial intelligence (AI) technology to address the increasing complexities of modern design. AI-enhanced tools augment the Synopsys Design Platform and work together with the company’s Fusion Technology to accelerate time-to-results (TTR) and set higher standards for quality-of-results in digital and custom design.

The announcement is the result of a multi-year Synopsys Design Group initiative and broadening investment in AI, in collaboration with multiple industry partners. It paves the road to a broader vision of intelligence in the Design Platform, allowing for orders-of-magnitude-improved automation and amplifying the abilities of design teams to create differentiated products.

Texas Instruments (TI) announced the addition of microcontrollers (MCUs) with integrated signal-chain elements and an improved operating temperature range to its MSP430 value line. MSP430FR2355 ferroelectric random access memory (FRAM) MCUs allow developers to reduce PCBsize and cost while meeting temperature requirements for sensing and measurement in applications such as smoke detectors, sensor transmitters and circuit breakers.

The signal-chain configurability lets engineers integrate analog combos—configurable signal-chain elements that include options for multiple 12-bit digital-to-analog converters and programmable gain amplifiers—along with a 12-bit analog-to-digital converter and two enhanced comparators.

Information concerning pricing and availability can be found on TI’s website.
