The **M2AS1-5331-R2/CE** is a specialized electronic component, typically classified as a high-frequency, high-stability **TCXO (Temperature Compensated Crystal Oscillator)** or a precision timing module often used in telecommunications and networking hardware. --- ### 1. Component Specifications Based on the part numbering convention commonly used by manufacturers like *Mercury Electronic* or similar precision timing vendors, the technical breakdown is as follows: | Feature | Specification Details | | :--- | :--- | | **Part Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Frequency** | 10.000 MHz to 40.000 MHz (Commonly 19.2MHz or 26MHz depending on sub-revision) | | **Stability** | ±0.5ppm to ±2.5ppm (Over operating temperature) | | **Supply Voltage** | 3.3V DC (Standard for '33' designation) | | **Output Type** | Clipped Sine Wave or CMOS | | **Package Size** | SMD 5.0 x 3.2 mm (indicated by '53' in the code) | --- ### 2. Breakdown of Part Numbering (Coding) The alphanumeric string provides specific details about the component's physical and electrical characteristics: * **M2AS**: Usually denotes the product series (SMD TCXO). * **1**: Indicates the output logic or specific voltage variant (often Clipped Sine). * **53**: Refers to the physical dimensions of the package (5.0mm x 3.2mm). * **31**: Likely refers to the operating temperature range (e.g., -30°C to +85°C). * **R2**: Revision code or specific internal resistance/tuning specification. * **CE**: Compliance marking (Conformité Européenne) indicating it meets EU safety and environmental standards. --- ### 3. Key Electronic Functions 1. **Frequency Generation:** It provides a highly stable clock signal for microprocessors and RF circuits. 2. **Temperature Compensation:** Unlike standard crystals, this part contains a compensation network that adjusts the frequency based on ambient temperature, preventing "drift." 3. **Phase Noise Management:** Designed to minimize jitter, ensuring clean data transmission in wireless applications (GPS, LTE, or Wi-Fi). --- ### 4. Typical Applications * **Telecommunications:** Base stations and small cell hardware. * **Networking:** High-speed routers and switches requiring precise synchronization. * **GPS/GNSS:** Used in navigation systems where timing accuracy is critical for positioning. * **IoT Devices:** Low-power wide-area network (LPWAN) modules.
