Fraunhofer Heinrich-Hertz-Institut (HHI) has initiated the SUSTAINET project, a €30 million research effort to develop sustainable and resilient network technologies. The project, running from January 2025 to December 2027, aims to integrate fiber optics, radio, and mobile networks to improve network availability and sustainability. It is divided into three sub-projects focusing on advanced technologies, intelligent solutions, and sustainable network architectures.

➀ The reference design TIDA-010128 by Texas Instruments (TI) presents a high-performance 20.8 GSPS sampling system using RF-sampling ADCs in a time-interleaved configuration.

➁ This design tackles challenges like offset, gain, and sampling time mismatch by utilizing the noiseless aperture delay adjustment feature of the ADC12DJ5200RF device.

➂ The design supports JESD204B with up to 32 lanes and includes a low-noise clock generator and a companion power reference design achieving over 85% efficiency.

➀ This article introduces a LIDAR-pulsed time-of-flight reference design using high-speed data converters from Texas Instruments (TI). It highlights the benefits of a high-speed data converter-based solution, such as improved target identification, reduced sample rate demands, and a simpler signal chain.

➁ The design supports a measurement range of up to 9 meters or more with additional optics and increased laser power. It achieves a range measurement mean error of less than ±6 mm and a standard deviation of less than 3 cm, ensuring high accuracy.

➂ The system uses a pulsed ToF measurement method with DFT-based range estimation for improved efficiency. Key components include 14-bit, 125-MSPS ADCs, 16-bit, 500-MSPS DACs, high-speed amplifiers, and precise clocking.
