Key Requirements and PCB Design in High-Speed Signal Generator DAC Applications

In high-speed signal generation applications, bandwidth and resolution are critical requirements. New signal generation applications utilize high-speed digital-to-analog converters (DACs) to produce various types of waveforms, including single tones with true hundreds of megahertz bandwidth and complex multi-channel waveforms. These applications require high-speed DACs to be fast enough to generate these waveforms without sacrificing analog … Read more

The Evolution of DAC Chips: From Early Designs to Modern High-Performance Solutions

A DAC (Digital-to-Analog Converter) serves as a bridge between the digital and analog worlds, and its development history is a chronicle of high-fidelity audio and precision industrial evolution. The core of DAC chip development revolves around the evolution from “sound production” to “high fidelity,” and then to “high integration and multifunctionality.” The main development line … Read more

24-bit PWM Pulse Width Modulation DAC (Part 1)

Unfortunately, my calibration source has malfunctioned. In the spirit of diligence and learning, I have thoroughly studied the principles of the FLUKE 5700 DAC and plan to document my learning process while also creating a test board for practical application. The FLUKE 5700 indeed uses PWM (Pulse Width Modulation) for DAC output: (1) It only … Read more

DAC: A Key Turning Point from Large-Scale Capture to Distributed PtX Microfactories

Introduction: DAC is at the most significant bifurcation since its inception. Over the past decade, DAC (Direct Air Capture) has been given excessive expectations: from the IPCC scenario models to the “negative emissions foundation” in carbon neutrality strategies, and to the massive subsidies from various governments, DAC is seen as a “million-ton infrastructure industry” capable … Read more

Pitfalls Encountered in DAC Applications

Recently, I used a SiC MOSFET to create a 200W power supply, and the debugging of the power section went relatively smoothly, achieving a full-load efficiency of 93.3%. However, I encountered issues while debugging the control board. This control board is mainly used to set reference values for voltage and current in the power section, … Read more

Core Technology Analysis of DAC: Which is More Suitable for Electrochemical CO₂ Conversion, Liquid Phase or Solid Phase?

In the global carbon neutrality framework, DAC (Direct Air Capture) is transitioning from a laboratory concept to a fundamental energy infrastructure. Meanwhile, electrochemical CO₂ conversion (CO₂ Electrolysis) is becoming an important pathway for green synthetic fuels, renewable chemicals, and negative carbon new materials. As DAC and CO₂ electrolysis, two originally independent technological systems, begin to … Read more

Zhenlei Technology: The King of ADC/DAC Chips

by

ADC/DAC chips, or analog-to-digital and digital-to-analog converters, are responsible for converting real-world analog signals, such as temperature, pressure, sound, fingerprints, or images, into a digital format that is easier to process. Conversely, DACs modulate digital signals into analog signals. ADCs and DACs serve as the bridge between the real world and the digital world, representing … Read more

Understanding AOC, DAC, ACC, and AEC Cables in Data Centers

by

Previously, we wrote an article about the NVL72 interconnection scheme. Some users in the community requested a further explanation of what these different cables in data centers mean. Let’s review where optical connections and copper connections are used in the GB200 standard. The abandoned NVL72 optical interconnection scheme regarding the GB200 architecture and interconnections has … Read more
