SiTime has announced that CellBounce, a division of ADT, has chosen the SiTime Elite Platform Super-TCXO for its 3G-to-4G conversion solution that is certified for use on the AT&T 4G cellular network.

“Our proprietary 3G-to-4G bridge solution requires very stable timing over its operating life,” said Jay Robertson, Senior Vice President of Product at ADT. “SiTime provides the right timing performance required by our solutions.”

SiTime MEMS-based Elite Super-TCXOs achieve an all-inclusive ±250 ppb frequency stability over ten years, which is ten times better than existing solutions. This performance provides many benefits – eliminating a calibration step in production testing, optimising network bandwidth utilisation, and reducing operating costs by eliminating run-time field calibration.

“The global move to faster 5G networks is driving the sunsetting of older 3G technology,” added Piyush Sevalia, Executive Vice President of Marketing at SiTime. “This transition opens up a plug-and-play upgrade opportunity at the client premises, and we are excited to help solve the timing challenges in this application.”

CellBounce is a plug-and-play conversion technology designed to solve one of the home security industry’s biggest logistical challenges in the next year and a half. Many home security customers with 3G radios in their security panels can receive and utilise the CellBounce device, similar to a smart plug, by simply plugging it into a power outlet near their security panel to enable continued cellular connection well beyond the 3G sunset.
