Euroquartz EHTF32 & EHTF21 Clock Oscillators – Fast UK Supply

Euroquartz, a UK-based manufacturer of frequency control products, has announced the launch of its latest clock oscillators, the EHTF32 and EHTF21. Designed and manufactured at the company’s Crewkerne facility, these new additions to the EHTF range offer a fast-turnaround solution for standard clock oscillators, making them ideal for small production runs, engineering prototypes, and addressing production shortfalls.

With ultra-miniature packaging, low phase jitter, and multiple voltage options, the new oscillators provide a reliable timing solution for a wide range of applications. The ability to source these components directly from a UK-based factory ensures reduced lead times, giving engineers and manufacturers greater flexibility in product development and production cycles.

The EHTF Oscillator Range

The EHTF series from Euroquartz is designed to meet the demands of modern electronics, offering high-performance clock oscillators in compact form factors. These oscillators are particularly well-suited for space-constrained applications, where maintaining signal integrity and timing accuracy is critical.

A key feature of the EHTF range is its ultra-low phase jitter, measured at just 0.9ps typical, ensuring minimal signal distortion and reliable performance in high-speed digital systems. The series is available in three input voltage options—1.8V, 2.5V, and 3.3V DC—allowing engineers to integrate these components into a wide range of circuit designs without additional voltage regulation.

With a focus on precision and efficiency, the EHTF oscillators provide a stable and dependable clock source, making them ideal for applications requiring consistent frequency performance and low power consumption.#

Package Variants & Frequency Range

The latest additions to the EHTF series come in two compact package options, providing flexibility for designs where board space is at a premium:

• EHTF32 – 3.2mm × 2.5mm package for applications requiring a balance between size and performance.
• EHTF21 – 2.0mm × 1.6mm package, offering an ultra-miniature footprint for densely populated circuit boards.

Despite their small form factors, both variants deliver high-precision frequency control, with a broad frequency range spanning from 1MHz to 200MHz. This makes them suitable for a wide range of applications, including high-speed data communication, embedded systems, and precision instrumentation, where maintaining a stable clock signal is essential.

Performance and Stability

The EHTF32 and EHTF21 oscillators are designed for high stability and reliability across a range of operating conditions. Available with frequency stability as low as ±25ppm, these oscillators cater to both commercial (0 to 70°C) and industrial (-40 to +85°C) environments, ensuring dependable performance in diverse applications.

Both variants feature CMOS output logic with a 15pF load capability, making them compatible with standard digital circuits while maintaining signal integrity.

Power efficiency is another key advantage of the EHTF range, with low current consumption between 30mA and 40mA, depending on frequency and voltage requirements. This makes them an ideal choice for battery-powered and energy-sensitive applications, where minimising power draw is essential.

Electrical and Timing Characteristics

The EHTF32 and EHTF21 oscillators are engineered for precise timing performance, ensuring reliable signal transitions and clock integrity in demanding applications.

• Fast signal response – With rise and fall times ranging from 0.5ns to 3ns, these oscillators support high-speed digital circuits while maintaining clean and stable waveform transitions.
• Output enable/disable function – This feature enhances power efficiency, allowing the oscillator output to be switched off when not in use, reducing unnecessary power consumption.
• Consistent duty cycle – Designed for stability, the oscillators maintain a 50% ±10% duty cycle, ensuring even signal distribution for synchronous operation.
• Minimal frequency drift – Long-term stability is supported by an ageing rate of ±3ppm per year at 25°C, reducing the need for frequent recalibration in precision applications.

With these characteristics, the EHTF range provides a dependable and efficient clock source for applications requiring accurate and stable timing performance.

Applications & Use Cases

The EHTF32 and EHTF21 oscillators are designed to meet the timing needs of a broad range of electronic systems, making them a versatile choice for engineers and manufacturers. Their compact size, low phase jitter, and wide frequency range ensure compatibility with various high-performance applications, including:

• Printers and multifunction printers – Providing stable clock signals for precise print head movement and image processing.
• Digital copiers – Ensuring accurate synchronization in scanning and reproduction processes.
• PDAs and networking equipment (LAN/WAN, routers) – Supporting high-speed data transmission with minimal signal distortion.
• Storage systems (CD-ROM, DVD, HDD) – Enabling consistent read/write operations in digital storage devices.
• Scanners, modems, and projectors – Offering reliable timing control for signal processing and display synchronization.
• Embedded systems and control electronics – Powering microcontrollers and embedded applications that demand precise timing and energy efficiency.

With their high stability and low power consumption, these oscillators are well-suited for both consumer and industrial electronics, ensuring reliable performance across diverse operating environments.
