Introduction to Pin Configurable/Selectable Oscillators

Pin configurable or selectable oscillators, also referred to as PC/SOs, are a type of clock or frequency synthesizer device. PC/SOs are designed to precisely control the frequency of a signal generated by a crystal or resonator. They can be used to generate frequencies in the hundreds of kilohertz range while using low cost components and a minimal amount of high performance external components. This makes them suitable for applications that require an easy to integrate solution to precisely control the output frequency.

The ASEMCHC: A Pin Configurable/Selectable Oscillator

The ASEMCHC is a highly integrated pin configurable/selectable oscillator that is capable of producing frequencies up to 200MHz with high frequency stability, low noise, and small sizes. The device integrates all the necessary components to generate multiple frequencies from several different quartz crystals. It features a dual rail architecture and uses two separate clock domains to generate two different clock outputs. The device utilizes patented Multiclock technology which can enable the device to switch easily between multiple clock source frequencies with a single input signal.

ASEMCHC Application Field and Working Principle

The ASEMCHC application field covers a wide array of signal processing related projects. It is most commonly used in embedded systems and communication networks, but is also applicable in medical and automotive systems.The device application and working principle is based on the underlying principle of digital signal processing. The device operates by taking a PC/SO (pin configurable/selectable oscillator) as its input, and performs a digital signal processing operation to generate a sinusoidal reference clock. The generated clock is used to enable the digital signal processor to dynamically adjust the output frequency for a given frequency range. The device employs various algorithms such as phase-locked loop (PLL) based frequency synthesis and digital signal processor based error correction mechanisms to produce a high frequency stability, low noise and small size clock.

Advantages

The advantage of using the ASEMCHC in signal processing related applications is that it is able to generate multiple frequencies from multiple quartz crystals while using minimal external components. It also provides a low power consumption and a high degree of frequency stability over temperature, aging and supply voltage. Additionally, the device is able to respond to external events quickly and accurately. Its on-chip configuration interface and security features make it a cost-effective solution compared to other pin configurable/selectable oscillators.
