As AI intelligence transcends beyond just smartphone applications and manifests itself in wearable forms like glasses, rings, and headphones that accompany us closely, a battle over every 'millimeter' intensifies within compact spaces. From watches on wrists to rings on fingers, from earbuds in ears to glasses on eyes, AI wearable devices are undergoing an extreme 'physical slim-down.' Behind the beautiful vision of 'unobtrusive wearability' lies an ultimate game of inches for hardware engineers on the cramped motherboard – how to pack greater computing power, longer battery life, and more complex sensors into a space smaller than a fingernail? This is not just an evolution of industrial design, but a technological breakthrough in a 'life-and-death struggle for every millimeter' of physical space.

YXC offers smaller, thinner, more accurate, and lower power consumption clock frequency device solutions, assisting developers in breaking through design limits in the smallest of spaces.

AI Wearables: kHz Crystal Selection

Miniaturization, High Precision

⦁ Application Scenarios

Timing and wake-up functions for smart rings, AI glasses, and smart bracelets.

⦁ Application Challenges

Wearable device motherboards are often irregularly shaped (e.g., elongated or curved), with extremely limited PCB space.

Traditional large-package crystals not only take up valuable space but also easily block signal line channels, forcing an increase in PCB size.

⦁ YXC Solution Advantages & Recommended Products

Offers a significant 50% to 60% or more reduction in area compared to traditional 3215 packages, with a thickness of only 0.5mm.

The extremely small package size allows for flexible placement in narrow gaps on the motherboard, freeing up more space for batteries and core components.

Recommended Product Series

AI Wearables: MHz Crystal Selection

Low ESR, Miniaturization

⦁ Application Scenarios

Wireless communication (Bluetooth/Wi-Fi) for AI earphones, AI glasses, and other devices.

⦁ Application Challenges

High-density wiring in AI wearables leads to significant interference.

If the crystal's ESR (Equivalent Series Resistance) is too high, it can cause startup difficulties or frequency jumps, leading to unstable Bluetooth/Wi-Fi connections and increased power consumption.

⦁ YXC Solution Advantages & Recommended Products

Provides low ESR specifications optimally reaching 40Ω-60Ω, ensuring sufficient oscillation gain margin in the circuit.

Maintains stable startup even in extremely small sizes, ensuring reliable RF transmission in complex environments.

AI Wearables: Active Crystal Oscillator Selection

Miniaturization, Low Power Consumption, High Stability

⦁ Application Scenarios

AI voice interaction, smart bracelet main chips, image processors, etc.

⦁ Application Challenges

Frequent wake-up of AI systems; startup delays waste idle current.

Traditional 3.3V supply voltage is often difficult to adapt to the requirements of new generations of ultra-low power SoCs.

⦁ YXC Solution Advantages & Recommended Products

Offers 2016/1612 micro-package active oscillators, supporting 1.2V power supply, perfectly matching slim designs.

Features millisecond-level fast startup in response to chip wake-up calls, significantly reducing standby and instantaneous power consumption.

Recommended Product Series

AI Wearables: RTC Selection

Integrated, Low Power Consumption, Power-Down Hold

⦁ Application Scenarios

Smart bracelets, health monitoring wearables, smart glasses.

⦁ Application Challenges

The RTC integrated into the SoC often has high power consumption and cannot maintain timing after power failure.

If using traditional discrete solutions, the external crystal not only takes up space but also struggles to keep time after the main battery is depleted, leading to invalid health monitoring data.

⦁ YXC Solution Advantages & Recommended Products

Adopts 3225 LGA miniaturized package with built-in crystal, eliminating the need for external matching capacitors, significantly freeing up PCB space.

Supports automatic backup battery switching, continuing timing with ultra-low current when the main power fails, ensuring continuous and uninterrupted timekeeping.
