The world's #1 timing device manufacturer.
Seiko Epson holds the leading position in the global crystals & timing market — and produces the broadest in-house portfolio of any manufacturer, from kHz crystals through to OCXOs and real-time clocks. TDE is your authorised European partner.
From wristwatches to the world's most precise timing devices.
Seiko Epson's origins lie in precision timekeeping. Founded in 1942 in Suwa, Japan, the company built its reputation on mechanical and quartz watches — and in 1969 introduced the world's first commercial quartz wristwatch, the Seiko Astron. The quartz expertise required for wristwatches scaled up into industrial-grade frequency control devices, and Epson became the world's largest producer.
Today, Seiko Epson is a global technology corporation listed on the Tokyo Stock Exchange. The Microdevices Division — which produces all crystals, oscillators, RTCs and OCXOs sold under the Epson brand — is a strategic pillar of the group, with dedicated R&D, fabrication and packaging facilities.
Epson is the only manufacturer with full vertical integration across all major timing device categories: from raw quartz processing through cutting, packaging, oscillator IC design, RTC integration, and oven-controlled assembly. No other supplier produces this complete portfolio in-house.
For industrial customers, this means: one design-in partner for the entire timing budget — crystal, oscillator, RTC and reference — with consistent quality systems, harmonised lifecycle communication, and the longest-running roadmap continuity in the industry.
Four product families covering the entire timing budget.
Click into any category to explore frequency ranges, package sizes and use cases. All Epson products are available across Europe through TDE — with engineering support, sample provisioning and lifecycle advisory.
Crystals
Quartz crystal units in kHz (tuning fork) and MHz (AT-cut) versions. Sizes down to 1.6 × 1.0 mm for IoT and wearable applications. Automotive-qualified to AEC-Q200.
Oscillators
SPXO, VCXO and TCXO families. Programmable variants, low-jitter PLL oscillators, and the new Myoshin clock buffer series with PCIe Gen 1–6 support.
Real-Time Clocks
Epson is the broadest RTC supplier on the market — from ultra-low-power (130 nA) for IoT, through automotive-qualified AEC-Q100 / Q200 devices for ADAS and BMS applications.
OCXO
Oven-controlled crystal oscillators for the most demanding stability requirements — 5G networks, IEEE 1588 synchronisation, optical modules and measurement equipment.
What makes them the right choice for industrial designs.
Vertical integration
Epson manufactures every step in-house: quartz growing, blank cutting, packaging, oscillator IC design, RTC integration, oven assembly. No outsourcing means consistent quality, predictable supply, and harmonised lifecycle policy across all four product families.
Lifecycle transparency
Among the industry's most comprehensive public EOL communication. Discontinued products, alternative recommendations, and PCN history are openly published — a critical input for long-lifecycle industrial designs and Risk-Check evaluations.
Automotive depth
The broadest AEC-Q100 / AEC-Q200 portfolio of any manufacturer: crystals, oscillators, RTCs, and OCXOs — all available with automotive qualification. ASIL-relevant designs benefit from harmonised supplier qualification documentation across categories.
Typical application profiles in DACH industry.
Automotive electronics
ADAS, BMS, infotainment, instrument clusters — AEC-Q100 / Q200 qualified parts with long lifecycle and supply commitments.
Industrial automation
PLC, motor controls, sensors — robust crystals and RTCs with extended temperature ranges and proven lifetime characteristics.
5G & networking
OCXOs and S3-TCXOs for 5G small cells, IEEE 1588 synchronisation, optical modules — with new clock-buffer integration via Myoshin platform.
Medical & IoT
Ultra-low-power RTCs (down to 130 nA) for battery-driven devices, plus miniature crystals for wearables and connected industrial sensors.
