Edge Computing

The core requirements of Edge AI are real-time data processing, low-latency decision-making, and offline operation capability. Crystal oscillators, as the "reference clock," directly determine the computational accuracy and communication stability of the device.

1. Application Scenarios and Products

• Edge Computing Gateway (localized data processing, small servers, data fusion platforms): Used with FPGA, TPU, and optical module DSP. Products used: Differential oscillators 100MHz, 125MHz, 156.25MHz, 200MHz. Passive crystals 25MHz, 24MHz. Real-time clock crystals: 32.768KHz

• Wireless Sensor Nodes (real-time environmental data collection and AI analysis, e.g., smart agriculture, forest fire prevention): Used with sensors and RF transceiver functions. Products used: Passive crystals: 25MHz, 27.12MHz, 26MHz, etc.

• Terminal Devices, Intelligent Surveillance Cameras (AI image recognition, e.g., face detection, abnormal behavior analysis): Used with terminal intelligent visual processors, video transmission, etc. Products used: Passive/active crystals: 27MHz, 25MHz, 24MHz, 32MHz, etc.

2. Role of Crystal Oscillators 

• Clock Synchronization: Ensures consistency in sensor data collection, AI inference operations, and inter-device communication timing, reducing recognition errors caused by data misalignment. 

• Low Power Consumption Control: Supports rapid switching between "sleep - wake" modes, suitable for battery-powered scenarios (e.g., field sensors). 

• High-Speed Signal Support: Provides stable reference clock for edge processors (e.g., FPGA, edge AI chips, DSP in optical modules), ensuring accuracy in million-level data operations per second.
