Siward Crystal Technology

What Siward Crystal Technology does

Siward Crystal Technology Co., Ltd. (希華晶體科技) is a Taiwan-domiciled, Taiwan Stock Exchange-listed manufacturer of quartz frequency control components, founded in 1988 and headquartered in Taiwan. The company operates as an independent, publicly-traded corporation with a standard governance structure (audit committee, compensation committee, board of directors) and discloses monthly revenue reports. Its business is entirely B2B component supply to electronics manufacturers; it does not sell finished consumer products.

The company's core technology exploits the piezoelectric effect of synthetic quartz crystal, and it maintains vertical integration across the full value chain: artificial quartz crystal growth, quartz wafer fabrication, SAW wafer production, and assembly of finished frequency control components. The product portfolio spans crystal units (MHz and 32.768 kHz tuning fork variants, including temperature-sensor-integrated SKUs), a full family of crystal oscillators (CMOS output, differential output, high-precision, low-jitter, low-phase-noise, low-power), temperature-compensated oscillators (TCXOs, VCTCXOs, low-phase-noise variants), voltage-controlled oscillators (VCXOs), and RF bonded wafers engineered for 5G NR filter applications. Notable performance benchmarks include 30 fs jitter at 312.5 MHz in a 2016 package and a 1.6 x 1.0 mm smallest form factor for 32.768 kHz tuning fork crystals. Automotive-grade products carry AEC-Q200 certification under an IATF16949 quality management system.

Siward sells to electronics manufacturers across seven primary end-markets: networking/communications, IoT and wearables, mobile phones, PC and consumer electronics, automotive electronics (EV, ADAS, infotainment), 5G telecommunications infrastructure, and data centers. Go-to-market combines direct B2B sales to Tier 1 chip customers, ODMs, and major OEMs with channel sales through authorized agents and global distributors, including formal listing on Digi-Key. Multi-year collaborative relationships with Tier 1 mobile chip customers and 5G infrastructure equipment manufacturers anchor volume. Pricing is contract-negotiated by volume and specification rather than publicly listed, consistent with standard electronic component distribution practices. No revenue figure, headcount, or specific funding history was disclosed in the source data.
