Pin configurable/selectable oscillators are designed to allow customers to make frequency choices at the time of ordering a product. The oscillator’s output frequency is easily set by external resistors, capacitors, diodes, and/or power supplies. The resulting flexibility enables customers to satisfy specific frequency requirements quickly and cost-effectively. One of the most commonly used pin configurable oscillators is the 554KC000403DGR, part of the SiTime EMCO 554K “nano-oscillator” family.

The 554KC000403DGR oscillator is a low frequency device. It has a frequency range of 100kHz to 400kHz, a voltage range of 1.8V to 3.3V, and a pull range (PP) of ±100 ppm. It is available in a variety of packages and has very low jitter. It operates over the full automotive temperature range of -40°C to +125°C. The oscillator is designed to be tolerant to supply voltage variation and electrical noise, reducing the risk of clock failure in harsh environments.

The 554KC000403DGR is designed for a wide range of applications, including industrial automation, storage systems, motor control, medical instruments, etc. It is also widely used in automotive applications, such as engine control systems, infotainment, and telematics. It has excellent thermal stability, making it suitable for use in applications that require reliable performance in high-temperature or varying temperature situations.

The 554KC000403DGR works on the principle of using a combination of pull-up and pull-down resistors to control the oscillator frequency. The frequency of the oscillator is determined by the ratio of the pull-up and pull-down resistors. When the resistor values are equal, the oscillator frequency is at the nominal value. When the resistors are unequal, the oscillator frequency varies from the nominal value, allowing the frequency to be adjusted. This principle of operation allows for wide frequency ranges and makes the device tolerant to voltage and temperature variations.

The 554KC000403DGR is easy to use and configure. It is available in a variety of packages and supports a wide range of input voltages, making it suitable for a variety of applications. It has a low jitter and has excellent thermal stability, making it suitable for use in harsh environments and in applications that require reliable performance in high-temperature or varying temperature situations. Its pull-up and pull-down resistor configuration makes it simple to change the frequency, while its wide frequency range ensures that it meets your requirements.
