The "24.000M" in the product name indicates that these oscillators are designed to operate at a nominal frequency of 24.000 MHz. They offer an extremely high level of frequency accuracy, with tolerances typically in the range of ±10 ppm (parts per million) to ±50 ppm. This high accuracy ensures that the oscillator can maintain a stable output frequency over a wide range of operating conditions, making it suitable for applications where precise timing is essential.
### 2.2 Temperature Stability
The HCM49 - 24.000MABJT series is engineered to exhibit excellent temperature stability. It can maintain its frequency accuracy within a specified range even when exposed to significant temperature variations. This is achieved through advanced crystal manufacturing techniques and the use of temperature - compensating circuits. The temperature range for stable operation can typically span from - 40°C to +85°C, making these oscillators suitable for use in both industrial and consumer applications.
### 2.3 Low Phase Noise
Phase noise is an important parameter in oscillator performance, especially in applications such as wireless communication systems and high - speed data transmission. The HCM49 - 24.000MABJT oscillators are designed to have low phase noise characteristics. This means that the output signal has minimal random fluctuations in phase, resulting in a cleaner and more stable signal. Low phase noise is crucial for reducing interference and improving the overall performance of the electronic system.
### 2.4 Compact Size
The HCM49 package is a well - established and widely used form factor in the industry. It offers a compact and standardized design, which allows for easy integration into printed circuit boards (PCBs). The small size of the HCM49 - 24.000MABJT oscillators makes them suitable for use in space - constrained applications, such as mobile devices, wearables, and small - form - factor electronic products.
### 2.5 High Reliability
These oscillators are built to meet high - quality standards and offer excellent reliability. They are subjected to rigorous testing during the manufacturing process to ensure that they can withstand various environmental stresses, such as shock, vibration, and humidity. The use of high - quality materials and advanced manufacturing techniques contributes to their long - term reliability, reducing the risk of component failure in the end - product.
## 3. Applications
