Find your timing component.
Crystals, oscillators, real-time clocks and OCXOs — from three world-class manufacturers, sorted by category, frequency and stability.
One curated portfolio. Three positioning tiers.
Seiko Epson
Full-portfolio in-house manufacturing — from kHz crystals to OCXOs and RTCs. Industry-leading EOL transparency, longest roadmap commitment.
- Full vertical integration
- Automotive AEC-Q100 / Q200
- Best for long-lifecycle designs
RIVER ELETEC
World's #1 share in miniature tuning-fork crystals. Patented electron-beam process; world's smallest 1.2×1.0 mm package. The hidden champion.
- World's smallest crystal packages
- Proprietary KoT Cut OPAW technology
- Best for size-constrained designs
UTECH
Three decades of focused frequency-control manufacturing. ISO 9001 / 14001 certified. The right choice for volume designs where price-performance matters most.
- Volume-tier pricing
- Crystals, oscillators, ceramic resonators
- Best for cost-sensitive designs
Four product families. Every frequency-control need.
Crystals
From 32.768 kHz tuning forks to 200 MHz AT-cut SMD crystals. Industrial, automotive AEC-Q200 and miniaturised packages down to 1.2 × 1.0 mm.
Oscillators
SPXO, VCXO and TCXO families with CMOS, LVDS, LVPECL outputs. Programmable variants, low-jitter PLL oscillators, and clock buffers for PCIe Gen 1–6.
Real-Time Clocks
Broadest RTC supplier on the market — from ultra-low-power (130 nA) for IoT, through automotive-qualified AEC-Q100/Q200 for ADAS and BMS designs.
OCXO & High-Stability
Oven-controlled crystal oscillators for the most demanding stability requirements — 5G networks, IEEE 1588 synchronisation, optical modules, measurement.
From the slowest tick to the highest reference.
Have a part number? We can cross-reference it.
Our database covers 934 entries across 24 manufacturers. Or send us your BOM — we'll quote you back within one business day with availability, pricing and lead times.
