Embedded World: TI on-chip oscillator vies with crystals for RF comms
The first two devices developed with TI BAW technology are the SimpleLinkTM CC2652RB wireless microcontroller (MCU) and the LMK05318 network synchronizer clock.
The resonator, built from piezoelectric material within the metallisation layers, is temperature-compensated and said to achieve better-than-some-crystals performance over temperature, vibration and ageing.

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 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• Reduced overall footprint: As the industry’s first crystal-less wireless MCU on the market, the CC2652RB integrates a BAW resonator within the quad flat no-lead (QFN) package, eliminating the need for an external high-speed 48-MHz crystal.
Simplified design: 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
• Higher network performance: 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.
• 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.
Package, availability and pricing
Preproduction samples of the CC2652RB are now available through the TI store in a 7-mm-by-7- mm very thin QFN (VQFN) package. Pricing starts at US$3.55 in 1,000-unit quantities. Developers can get started with the SimpleLink CC2652RB wireless MCU-based TI LaunchPadTM development kit available through the TI store.
The LMK05318 is available in a 48pin, 7 x 7mm VQFN package.
Developers can evaluate this device with the LMK05318 evaluation module, available for $399.00.
