BAW resonator technology improves performance; is immune to vibration/shock

Designers can reduce the bill of materials cost, improve network performance and increase immunity to vibration and shock using the bulk acoustic wave (BAW) –based embedded processing and analogue chips developed by Texas Instruments.

The first two devices, developed for the next generation of connectivity and communications infrastructure and using TI BAW technology are the SimpleLink CC2652RB wireless microcontroller and the LMK05318 network synchroniser clock. Texas Instruments says they will help system designers streamline design logistics for faster time to market, while enabling stable, simplified and high-performance data delivery.

The SimpleLink CC2652RB and the LMK05318 integrate reference clocking resonators to provide the highest frequency in a small form factor, claims Texas Instruments. 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 synchronisation of wired and wireless signals is more precise and allows for continuous transmission, which means data can be processed quickly and seamlessly, adds the company.

The SimpleLink multi-standard CC2652RB wireless microcontroller is believed to be the industry’s first crystal-less wireless microcontroller. It integrates a BAW resonator within the quad flat no-lead (QFN) package, eliminating the need for an external high-speed 48MHz crystal.

It is also claimed to be the lowest power multi-standard device supporting Zigbee, Thread, Bluetooth low energy and proprietary 2.4GHz connectivity on a single chip. Operating temperature range is -40 to +85 degrees C temperature range.

The low jitter single-channel LMK05318 network synchroniser clock has a BAW resonator and is a single-channel network synchroniser clock for 400Gbits per second links for fast data transmission with what is claimed to be a higher margin for system jitter budgets than competing devices. With low jitter and the industry’s best hitless switching performance, the LMK05318 delivers the lowest bit errors for 56Gbits per second and emerging 112Gbits per second pulse-amplitude modulation-4 links, says Texas Instruments, to improve network performance.

No in-system programming is required, and with simplified power-supply requirements and a reduced bill of materials for ancillary components, the LMK05318 streamlines the PCB design phase compared to competing solutions, claims Texas Instruments, while offering increased clocking performance.

Pre-production samples of the CC2652RB are available now in a 7.0 x 7.0mm very thin QFN (VQFN) package.

The LMK05318 is now available in production quantities in a 48-pin, 7.0 x 7.0mm VQFN package.
