Miniature SPXO for Low-Power Application

Miniature Clock Oscillators for Space-Constrained, Low-Power Designs

Modern electronic products are becoming smaller, lighter and more energy efficient. To support these design goals, engineers need frequency control components that deliver dependable timing performance without taking up valuable board space.

IQD’s miniature clock oscillators provide a compact, reliable timing solution for applications where size, power consumption and stable frequency performance are critical. The IQXO-54x and IQXO-64x SPXO series are designed for space-constrained electronics, including wearable technology, IoT devices and portable, battery-powered equipment.

Flexible voltage options with the IQXO-54x series

The IQXO-54x series gives engineers flexibility when designing compact electronic systems. It is available with three supply voltage options: 1.8 V, 2.5 V, 3.3 V

This choice of supply voltages makes the IQXO-54x series suitable for a wide range of low-power architectures. Engineers can select a miniature clock oscillator that aligns with their system requirements while supporting efficient power management and streamlined PCB design.

Ultra-compact frequency control with the IQXO-64x series

Where board space is especially limited, the IQXO-64x series delivers the benefits of miniature frequency control in an even smaller package. Measuring just 1.6 x 1.2 mm, this ultra-compact SPXO series helps engineers optimise board layouts.

Designed for wearables, IoT and portable electronics

The ultra-compact packages of both SPXO families help simplify the design of space-constrained products without compromising the need for reliable frequency control. Their compact form factor and low-power design focus make them a practical choice for applications such as:

  • Wearable technology
  • Consumer and industrial IoT devices
  • Portable and battery-powered electronics 
  • Compact medical and healthcare equipment
  • Mobile and connected devices
  • Space-constrained embedded systems

By combining compact dimensions with dependable timing performance, the IQXO-54x and IQXO-64x series support engineers in developing smaller and more efficient products.
