Semtech Announces Intelligent Sensor Platform, PerSe™, Improving Mobile Connectivity and Compliance for Personal Connected Consumer Devices

PerSe™ portfolio features three new product lines – PerSe Connect, PerSe Connect Pro and PerSe Control

CAMARILLO, Calif., Oct. 27, 2021 – Semtech Corporation (Nasdaq: SMTC), a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, announced its PerSe™ line of sensors targeted for the personal connected consumer device market. Derived from the name, Person Sensing, the PerSe product family consists of three core product lines – PerSe Connect, PerSe Connect Pro and PerSe Control – delivering ground-breaking user experiences in smartphones, laptops and wearables by intelligently and automatically sensing human presence.

PerSe sensors intelligently sense human presence near the mobile device and other consumer electronics, and enable advanced Radio Frequency (RF) control when the user is in close proximity. Its unique smart human sensing feature, ultra-low power and tiny footprint also make it the ideal sensing solution for a wide range of wearable applications such as gesture control and automation.

The demand for 5G smartphone continues to grow rapidly and, according to IDC, is expected to make up more than half of all global shipments by the end of 2022. By leveraging Semtech’s PerSe technology, leading consumer electronics manufacturers can now deliver high-quality connectivity in 5G/Wi-Fi 6 with increased RF performance in their smartphones and laptops, while also helping ensure compliance with the worldwide Specific Absorption Rate (SAR) regulations, keeping consumers connected and safe. PerSe provides best-in-class sensing performance and robust noise immunity allowing original equipment manufacturers (OEMs) and original device manufacturers (ODMs) to design devices with longer detection distance within a smaller sensor area.

“Semtech has more than a decade of market-leading sensor technology experience. We work closely with the industry’s top consumer electronics manufacturers developing and implementing our sensors to deliver incredible connectivity and provide an automated user experience, while also complying with SAR regulations,” said David Wong, senior director of consumer sensing products for Semtech’s Wireless and Sensing Products Group. “Today’s launch further underscores our commitment and leadership in the personal connected consumer device market. PerSe sensors deliver an unmatched consumer experience through device performance, regulatory compliance, user safety, and business impact.”

Semtech’s PerSe portfolio includes:

  • PerSe Connect: Enhances connectivity for many of the global smartphones and laptops (5G Sub-6, 4G and Wi-Fi). The sensors help optimize the RF power for best connectivity and help to maintain SAR compliance while delivering a fast wireless experience on these devices.
  • PerSe Connect Pro: First of its kind to provide ultra-high sensing performance for high band 5G mmWave devices in smartphones, laptops and tablets. PerSe Connect Pro enables higher sensing distance to safely manage the increased RF exposure.
  • PerSe Control: Enables smarter control in wearables to improve the user experience. PerSe Control enables human detection, automatic on/off and start/stop response. It also delivers cutting-edge gesture control and response including smart assistant, noise cancellation activation and media player control.

Said Joe Hoffman, director, intelligent edge & sensor technologies research at SAR Insight: “Smart devices need smart sensors to rise above the competition. However, mobile, portable and wearable devices complicate the design window of performance, battery life and human RF absorption. Smart sensors, such as the PerSe portfolio from Semtech, can differentiate between humans and inanimate objects, including handheld positions. This advanced sensing capability is essential for mobiles, wearables and 5G mmWave devices to deliver a superior user experience.”

See 400 GbE Running on a Speedster®7t FPGA from Achronix

Sponsored by Achronix

400GbE is required for next-generation, high-performance networking applications. In this video, Achronix demonstrates 400GbE connectivity on a Speedster7t FPGA integrated into a VectorPath™ PCIe accelerator card. The demonstration shows 400GbE traffic generated within the FPGA and transmitted across the FPGA’s 2D network on chip or NoC to the Ethernet subsystem. The 400GbE traffic is then looped back and checked within the FPGA fabric to compare to the original data stream.

Enhancing PSAP Audio Performance and Power Efficiency in Hearables with Anti-Noise

Sponsored by Maxim Integrated (now part of Analog Devices)

Personal sound amplification products (PSAP) enhance user’s listening experiences with hearables in challenging environments. Long delay in the audio system creates distortion known as comb effect in PSAP. This paper investigates the root cause of the comb effect and explains how Maxim’s PSAP based on anti-noise solution yields a superior system performance than conventional PSAP solutions.
