BAW resonator technology-based devices debut at embedded world

Based on Texas Instruments (TI) bulk acoustic wave (BAW) technology the SimpleLink CC2652RB wireless microcontroller (MCU) and the LMK05318 network synchronizer clock will help system designers streamline design logistics for faster time to market, while enabling stable, simplified and high-performance data delivery, which in return, allows for potential overall development and system cost savings.

TI describes the devices as embedded processing and analogue chips for the next generation of connectivity and communications infrastructure.

Communications and industrial automation systems with discrete clocking and quartz-crystal devices can be costly, time-consuming and complicated to develop and are often susceptible to environmental stress, including vibrations and temperature variations.

These new devices integrate reference clocking resonators to provide the highest frequency in a small form factor. This higher level of integration improves performance and increases resistance to mechanical stresses, such as vibration and shock.

As a result of stable data transmission enabled by TI BAW technology, data synchronization of wired and wireless signals is more precise and allows for continuous transmission, which means data can be processed quickly and seamlessly to maximize efficiency.

At embedded world 2019, TI is demonstrating how designers working on data transfer, building and factory automation, and grid infrastructure equipment can take advantage of this technology to develop higher performing systems while minimizing system cost, size and design complexity.

Key features and benefits of the SimpleLink multi-standard CC2652RB wireless MCU include reduced overall footprint saving board space.

As the industry’s first crystal-less wireless MCU on the market, the CC2652RB integratesa BAW resonator within the quad flat no-lead (QFN) package, eliminates means that the CC2652RB is the lowest power multi-standard device supporting Zigbee, Thread, Bluetooth low energy and proprietary 2.4-GHz connectivity solutions on a single chip.

Enabling more design options and flexibility in a wider range of applications and environments, the CC2652RB works in the full -40°C to 85°C temperature range, unlike many crystal-based solutions currently on the market.

Key features and benefits of the ultra-low jitter single-channel LMK05318 network synchronizer clock include higher network performance.

Featuring a BAW resonator, the single-channel network synchronizer clock for 400-Gbps links helps systems transmit more data faster while also providing higher margin for system jitter budgets than competing devices.

With ultra-low jitter and the industry’s best hitless switching performance, the LMK05318 delivers the lowest bit errors for 56-Gbps and emerging 112-Gbps pulse-amplitude modulation-4 links – enabling better network performance.

With no in-system programming required, simplified power-supply requirements and a reduced bill-of-materials(BOM) for ancillary components, the LMK05318 streamlines the printed-circuit-board design phase compared to competing solutions while offering increased clocking performance.

Preproduction samples of the CC2652RB are now available through the TI store in a 7-mm-by-7-mm very thin QFN (VQFN) package. Developers can get started with the SimpleLink CC2652RB wireless MCU-based TI LaunchPad development kit available through the TI store.

The LMK05318 is now available in production quantities through the TI store and authorized distributors in a 48-pin, 7-mm-by-7-mm VQFN package. Pricing starts at US$11.44 in 1,000-unit quantities. Developers can evaluate this device with the LMK05318 evaluation module.
