Frequency Components for Audio Applications

Looking for the ultimate in dynamic range?
Make sure nothing degrades the performance of your DAC or audio project by using Golledge's low jitter, high SNR components.

For high-end audio nothing is more important than ensuring purity of signal.

Perturbations, phase-noise/jitter and poor locking ability can all interrupt the smooth flow of signal between audio modules.

Golledge’s range of products recommended for high-end audio avoid spurious resonances by using only the highest quality quartz and mounting techniques. This helps to decrease the likelihood of unwanted perturbations affecting your tuning curves or control loops.

We also offer VCXOs with wide pullability, ensuring ease of locking between audio modules.

All of our audio-recommended products also feature fantastically low jitter specifications, meaning you don’t need to worry any longer about introducing noise into the output of your DAC. We also offer ultralow phase noise OCXOs for those wanting the ultimate in clean audio reproduction.

Our expert in-house engineering department can help with any custom requirements, testing and specifications you require, if you need a custom part please get in touch, we'd love to help.

Golledge uses in-house engineering expertise to reduce your time to market

Our experience in serving the audio industry means we are able to offer specialist testing and product engineering to ensure our customers get exactly what they need, and reduce the length of time our customers spend sourcing custom-requirements.

This meant that when a team of top audio engineers approached us looking for some very specific VCXO requirements we were able to help. The engineering team were looking for the minimum of perturbations, maximum pulling range, and low jitter, and we were able to create a custom suite of testing and temperature cycling to ensure every VCXO they receive offers the cleanest clock signal for their DAC product, a signal highly prized by their audiophile customers.

Golledge components can help reduce noise within audio applications for the cleanest signal possible.
