The **M3A61TAG-R** is a specific electronic component, primarily identified as a high-performance **Oscillator** (often a Temperature Compensated Crystal Oscillator or TCXO) or a specialized timing module used in telecommunications and industrial networking. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The M3A series is typically associated with high-precision frequency control. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Crystal Oscillator (TCXO / VC-TCXO) | | **Package Type** | Surface Mount Device (SMD) | | **Frequency Range** | Typically 10MHz to 52MHz (Model specific) | | **Operating Voltage** | 3.3V (standard for the "3" series designation) | | **Output Type** | Clipped Sine Wave or CMOS | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Key Electronic Parts & Functionality The internal architecture of the M3A61TAG-R consists of several integrated layers: * **Quartz Crystal Resonator:** The heart of the component that provides the fundamental vibration frequency. * **Temperature Compensation Circuit:** An analog or digital circuit that adjusts the load capacitance to counteract frequency drift caused by temperature changes. * **Buffer Amplifier:** Ensures the output signal is strong enough to drive the load without affecting the stability of the resonator. * **Voltage Regulator:** Internal regulation to minimize frequency fluctuations caused by power supply noise (PSRR). --- ### 3. Pin Configuration For standard SMD packages in this series (typically 4 or 6 pads), the layout is usually as follows: | Pad Number | Function | Description | | :--- | :--- | :--- | | **1** | Vc or NC | Voltage Control (for tuning) or No Connection | | **2** | GND | Ground Connection | | **3** | Output | The frequency signal output | | **4** | Vcc | Positive Supply Voltage (3.3V) | --- ### 4. Common Applications Due to its high stability and small footprint, the M3A61TAG-R is found in: 1. **Wireless Communication:** Base stations and small cells. 2. **GPS/GNSS Receivers:** Providing precise timing for satellite synchronization. 3. **IoT Gateways:** Ensuring stable data transmission over long distances. 4. **Network Switches:** Clocking for high-speed Ethernet physical layers. ---
