Exploring Frequency Control Products for Automotive Applications

10 Oct 2023


In today's digital era, the automotive industry rapidly integrates cutting-edge electronics to enhance vehicle performance, safety, and user experience. Central to this evolution is an important role played by frequency control.

Within this dynamic landscape, Golledge Electronics emerges as the UK's leading supplier of frequency control products. Having pioneered numerous innovations, Golledge has been instrumental in steering the frequency control industry forward, catering to the nuanced demands of the automotive sector, among others. 

Frequency Control Products in Automotive Electronics

Frequency control products are often unrecognised electronic devices, especially within the automotive sector. At their core, these products are electronic components designed to maintain stability, ensuring that clocking and timing processes in digital circuits transpire at precise intervals. 

Every digital device, from the infotainment system in your car to the advanced driver-assistance systems (ADAS), relies on these frequency control products. They ensure that every digital process, whether the deployment of an airbag or the precise tuning of a radio station, happens right on cue. These advances would ensure the synchronicity and responsiveness we've come to expect from our vehicles' electronics.

In the automotive electronics landscape, the role of frequency control products is essential, providing life and rhythm to the myriad of electronic functions that seamlessly integrate into our driving experience. 

Common Frequency Control Challenges in Automotive Applications:

Automotive electronics operate under demanding conditions, constantly subjected to various external and internal challenges. The quest for stability, especially with frequency control, is perpetual. Here are two of the common challenges:

Temperature fluctuations: The fluctuation exposes vehicles to various temperature extremes that can influence electronic components' stability, including those responsible for frequency control. For instance, when exposed to extreme temperatures, oscillators and quartz crystals may drift from their designated frequencies. 

Constant movement: Vehicles are in constant motion, with surfaces ranging from smooth highways to rugged off-road terrains. Such actions lead to vibrations that can alter these components' timing accuracy, cascading into more significant systemic issues within the electronic systems. 

At Golledge Electronics, navigating these challenges requires meticulous engineering and robust product design. It's a testament to the complexity of the automotive world, where even the minutiae can have substantial implications for vehicle performance and safety. 

Key Frequency Control Products for Automotive Systems:

Automotive electronics is an intricate ecosystem, with several components diligently working behind the scenes. Let's explore the key frequency control products that ensure our vehicles function with the precision we've come to expect. 

Quartz Crystals: The Cornerstone of Precision Timing

Quartz Crystal are naturally occurring structures that possess piezoelectric properties. Voltage application to a quartz crystal causes a slight deformation of the crystals shape. The process also works in the other direction with deformation causing a voltage to be generated. In this way a mechanical resonance in the structure of the crystal is turned into an electrical resonance. The mechanical resonance can be very stable and accurately set by polishing end fine adjustments to the mass of the electrodes. This unique property makes them indispensable in the realm of electronic timing. 

They act as the 'reference' point for timing. When other components or systems deviate due to external factors like temperature or vibration, the quartz crystal provides a constant, allowing corrections and ensuring stability. 

Oscillators: The Frequency referance

Oscillators are electronic circuits that produce a repetitive, oscillating signal, often taking the stable reference from a quartz crystal and generating a continuous waveform, like a sine or square wave. They are pivotal in transforming the consistent frequency from a quartz crystal into signals that can drive other electronic components. 

While standard oscillators do an admirable job, automotive electronics often demand higher precision.

 As a result, Temperature Compensated Crystal Oscillators (TCXOs) come into play.

TCXOs are a step ahead of the standard variants. They incorporate circuitry that adjusts the oscillator's frequency based on temperature fluctuations, ensuring that the output remains stable even as environmental conditions change. 

OCXOs, on the other hand, take precision to another level. They house the quartz crystal in a temperature-controlled chamber or 'oven'. By maintaining the crystal at a constant temperature, these oscillators can deliver unparalleled frequency stability, making them invaluable in applications where even the slightest deviation could be critical. 

Crystal and SAW Filters: The Signal Custodians

Electronic signals surround us, which is why interference is inevitable. Find out how Surface Acoustic Wave (SAW) filters and Crystal filters can help.

Crystal filterscapitalise on the piezoelectric properties of quartz crystals to allow specific frequencies to pass through while blocking others. They're the gatekeepers, ensuring the desired signals remain clear and interference-free. 

SAW filters operate by generating sound waves on a chip's surface. They filter out unwanted frequencies, ensuring clarity in electronic transmissions. Their compact nature and ability to function at higher frequencies make them particularly useful in modern automotive systems. 

RTC Modules: The Timekeepers

In a world that's racing against time, Real-Time Clock (RTC) modules ensure our automotive systems keep pace. They provide accurate timekeeping, integrating seamlessly into vehicles' electronics, ensuring functionalities like event logging, timestamping, and system synchronisation occur flawlessly. 

RTC modules contain an oscillator usually driven by a quartz crystal and circuitry that translates the oscillator's frequency into time units. Whether the car's infotainment system displays the correct time or the engine control unit logs data, RTC modules play an understated but crucial role. 

While we often marvel at the visible advancements, the quartz crystals, oscillators, filters, and RTC modules truly drive the precision and reliability of our modern vehicles. Find out more about how automotive control is optimised.

Optimising Performance and Reliability in Automotive Frequency Control

At Golledge Electronics, optimising the performance and reliability of frequency control components is a top-tier priority, as the synergy of these parts directly impacts the vehicle's performance, safety, and user experience. Here is how we do it: 

Selecting the Right Tool for the job

Choosing the right product that aligns seamlessly with the specific needs of the vehicle's system is crucial. A mismatch or subpar component can compromise the system's reliability and functionality. For instance, an advanced system requiring impeccable timing would benefit more from an TCXO than a standard oscillator.

One notable trend is the rise of Vehicle-to-Everything (V2X) communication. As cars communicate with other vehicles, infrastructures, and pedestrians, precise and reliable frequency control becomes paramount. Miscommunications or slight time lags can have severe consequences on the road. 

Moreover, with the advent of autonomous vehicles, precision in frequency control isn't just a matter of performance – it's a matter of safety. These self-driving cars will rely heavily on sensors, LiDAR, and real-time data processing. Every millisecond will count, and ensuring synchronisation of all systems will be paramount. 

Soon, we can anticipate advancements in frequency control products to offer even more stability against temperature extremes, vibration resistance, and other automotive challenges.
