BAW resonator technology to shrink BOM

These devices 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 synchronisation of wired and wireless signals is more precise and allows for continuous transmission, which means data can be processed quickly and seamlessly to maximise 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 minimising system cost, size and design complexity.

Key features of the SimpleLink CC2652RB wireless MCU:

• Reduced overall footprint: As a crystal-less wireless MCU, the CC2652RB integrates a BAW resonator within the quad flat no-lead (QFN) package, eliminating the need for an external high-speed 48MHz crystal.
• Simplified design: The CC2652RB is the lowest power multi-standard device supporting Zigbee, Thread, Bluetooth low energy and proprietary 2.4GHz 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.

Key features of the LMK05318 network synchroniser clock: 

• Higher network performance: Featuring a BAW resonator, TI’s new single-channel network synchroniser clock for 400Gbps 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 56Gbps and emerging 112Gbps pulse-amplitude modulation-4 links, enabling better network performance.
• Intuitive design: 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 in a seven by seven millimetre very thin QFN (VQFN) package. Pricing starts at $3.55 in 1,000 unit quantities. Developers can get started with the SimpleLink CC2652RB wireless MCU-based TI LaunchPad development kit.

The LMK05318 is now available in production quantities t in a 48-pin, seven by seven millimetre VQFN package. Pricing starts at $11.44 in 1,000-unit quantities. Developers can evaluate this device with the LMK05318 evaluation module.
