What IQD Frequency Products does

IQD Frequency Products is a UK-based specialty manufacturer of frequency control components, founded in 1973 and headquartered in Crewkerne, Somerset. The company designs and produces a comprehensive range of quartz crystals (kHz and MHz), clock oscillators (SPXO), temperature-compensated oscillators (TCXO/VCTCXO), voltage-controlled oscillators (VCXO), oven-controlled oscillators (OCXO), GPS-disciplined OCXOs, and rubidium atomic clocks, including AEC-Q200 compliant variants for automotive applications. Notable proprietary offerings include the ICPT-1 chip-scale atomic clock based on Coherent Population Trap technology, the IQXC-240 miniature quartz crystal at 1.2 x 1.0 x 0.33 mm, and ultra-low phase noise SPXOs with jitter down to 40 fs RMS. The company is a member of the Würth Elektronik eiSos group, one of Europe's largest passive component manufacturers, and is a participant in the CERN-led White Rabbit Collaboration, having co-developed the White Rabbit Switch v4 holdover expansion board with GMV.

IQD generates revenue through direct hardware sales from its UK headquarters and through a global network of authorized distribution partners and Würth Elektronik's channel spanning over 80 countries. Pricing is quote-based with no public list pricing, and product positioning spans economical commercial-grade components through to high-reliability extended-temperature parts for aerospace, defense, telecommunications infrastructure, industrial, medical, and scientific research applications. The company serves six primary verticals with communications, aerospace and defense, industrial, and medical designated as primary segments, and computing and consumer electronics as secondary segments. Regional sales offices in North America and Germany supplement the UK head office.

IQD maintains ISO 9001:2015 and ISO 14001:2015 certifications across the organization and partners with premier IC designers with approved status on multiple reference designs, embedding its components into third-party semiconductor platforms. The go-to-market is sales-led with channel partner distribution, supported by technical content marketing including datasheets, application notes, YouTube technical training videos, and participation in industry events such as Embedded World, APEC, and the CERN White Rabbit Workshop.

Core offering

IQD Frequency Products manufactures and sells frequency control components including quartz crystals (kHz and MHz ranges), clock oscillators (SPXO), temperature-compensated oscillators (TCXO/VCTCXO), voltage-controlled oscillators (VCXO), oven-controlled oscillators (OCXO), disciplined OCXOs, and rubidium atomic oscillators. The portfolio spans commercial-grade to high-reliability, extended-temperature solutions for aerospace, communications, computing, industrial, medical, and consumer electronics manufacturers. Custom product development, application engineering support, and component testing services are also provided from design stage through mass production.

Product overview

IQD Frequency Products offers a comprehensive portfolio of frequency control components organized into two main categories: Quartz Crystals (kHz and MHz ranges) and Oscillators (SPXO, TCXO/VCTCXO, VCXO, OCXO, Disciplined OCXO, Rubidium Oscillators, and Fast Make Oscillators). The company also provides AEC-Q200 compliant products for automotive applications. The product lineup includes specialized sub-products such as the ultra-low phase noise IQXO-408/455 series for 5G and fiber applications, miniature IQXO-54x/64x series for IoT and wearables, and the smallest SMD OCXO (IQOV-116). The rubidium oscillator range includes the ICPT-1 chip-scale atomic clock using Coherent Population Trap technology, the IQRB-1 sub-miniature atomic clock, and the IQRB-2 with the lowest phase noise in the rubidium portfolio. IQD serves diverse markets including aerospace, communications, computing, consumer, industrial, and medical sectors, offering solutions from economical commercial-grade components to high-reliability extended temperature products.
