SUNTAN TECHNOLOGY COMPANY LIMITED · ALL KINDS OF CAPACITORS

Selecting the right SMD quartz crystal is a critical step in achieving stable clock performance for both MCU clock crystal and RTC crystal 32.768kHz applications. Package size alone is not enough. Frequency range, crystal structure, ESR, and application type must be considered together to avoid startup failures or long-term drift.

This guide explains how to approach SMD quartz crystal selection based on real design requirements, using three Suntan standard products as references: Suntan TSQ-3225SMD, Suntan TSQ-2016SMD, and Suntan TSQ-3215SMD.

MCU Clock Crystal Selection (High-Frequency Designs)

MCU and SoC designs typically require crystal frequencies in the MHz range to drive system clocks, communication timing, or peripheral control. For these applications, AT-cut fundamental-mode crystals are commonly used.

Key Selection Factors for MCU Designs

• Operating frequency range
• Equivalent Series Resistance (ESR)
• Package size and PCB layout constraints
• Compatibility with reflow soldering

RTC Crystal 32.768kHz Selection (Low-Power Timekeeping)

RTC circuits operate differently from MCU clocks. They rely on 32.768 kHz tuning-fork crystals optimized for ultra-low power consumption and long-term frequency stability.

MCU vs RTC Crystal Selection Summary

• MCU clock designs use MHz-range AT-cut crystals
• RTC designs use 32.768 kHz tuning-fork crystals for low-power timekeeping
• Do not interchange MCU and RTC crystals due to fundamentally different operating requirements
