TI: BAW resonator technology paves the way for next gen communications

Texas Instruments announced new bulk acoustic wave (BAW)-based embedded processing and analog chips for the next generation of connectivity and communications infrastructure. The first two devices developed with TI BAW technology, the SimpleLink CC2652RB wireless microcontroller 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

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. The new devices with TI BAW resonator technology 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.

As the industry’s first crystal-less wireless MCU on the market, the CC2652RB integrates a BAW resonator within the QFN package, eliminating the need for an external high-speed 48-MHz crystal.

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 to 85°C temperature range, unlike many crystal-based solutions currently on the market.

Featuring a BAW resonator, TI’s new 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.
