Based on the part number **M3A62FBX-R**, this component is a specific configuration of a high-performance **Crystal Oscillator** or **TCXO (Temperature Compensated Crystal Oscillator)** typically manufactured by **MtronPTI**. These components are critical in telecommunications and aerospace applications for providing stable frequency references. --- ## Technical Specifications & Features The following table outlines the general electronic characteristics associated with the M3A series: | Parameter | Typical Specification | | :--- | :--- | | **Output Type** | CMOS / HCMOS | | **Frequency Range** | Typically 1.0 MHz to 160 MHz | | **Supply Voltage** | 3.3V (Commonly indicated by '3' in series) | | **Stability** | ±1.0ppm to ±5.0ppm (Temp dependent) | | **Package Size** | 5.0 x 7.0 mm (Surface Mount Device) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ## Breakdown of the Part Number Structure While specific manufacturer prefixes can vary slightly, the nomenclature usually follows this logic: ### 1. Series (M3A) * **M:** Refers to the manufacturer series (MtronPTI). * **3:** Generally indicates a **3.3V DC** operating voltage. * **A:** Specific designator for internal architecture or output type (often HCMOS). ### 2. Stability & Temperature (62) * These digits usually correspond to the frequency stability over a specific temperature range. For example, "62" might denote a stability of ±2.0 ppm over -40°C to +85°C. ### 3. Package & Function (FB) * **F:** Fixed Frequency (as opposed to Voltage Controlled). * **B:** Refers to the physical package footprint (7x5mm Ceramic Leadless Chip Carrier). ### 4. Special Options (X-R) * **X:** Often denotes custom requirements or high-reliability screening. * **-R:** Indicates compliance with **RoHS** (Lead-Free) standards or **Tape & Reel** packaging. --- ## Key Applications The M3A62FBX-R is designed for environments where frequency drift must be minimized: 1. **Networking Hardware:** Switches and routers requiring precise timing for data packets. 2. **Wireless Infrastructure:** Base stations and point-to-point microwave links. 3. **Test & Measurement:** Oscilloscopes and frequency counters. 4. **Avionics:** Systems requiring stable performance despite high temperature fluctuations.
