## Technical Overview: M3V11T2J-R The **M3V11T2J-R** is a specific part number typically associated with **Surface Mount (SMD) Quartz Crystal Oscillators**. These components are essential in electronic circuits for providing precise timing signals or clock frequencies. --- ### 1. Component Specifications Based on the standard nomenclature for this series (often produced by manufacturers like *Kyocera* or *NDK*), here are the typical technical characteristics: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Size** | 3.2mm x 2.5mm (SMD) | | **Output Type** | CMOS | | **Supply Voltage** | 3.3V (Standard for V11 series) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±50ppm (Typical for this grade) | --- ### 2. Functional Electronic Parts Inside the M3V11T2J-R, the device is composed of three primary electronic sub-elements integrated into one ceramic package: 1. **Quartz Crystal Blank:** The heart of the component. It uses the piezoelectric effect to vibrate at a specific resonant frequency. 2. **Oscillator IC:** An internal integrated circuit that provides the necessary gain to maintain oscillation and buffers the output signal. 3. **Varactor Diode (VCXO Specific):** Since this is a "Voltage Controlled" model, it includes a varactor that changes capacitance based on an input voltage (Control Voltage), allowing for slight adjustments to the output frequency. --- ### 3. Pin Configuration These devices generally feature a 4-pin or 6-pin layout. The typical 6-pin assignment for the M3V11 series is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **V_c** | Control Voltage (Frequency adjustment) | | **2** | **INH / E/D** | Inhibit or Enable/Disable function | | **3** | **GND** | Circuit Ground | | **4** | **Output** | Clock Signal Output | | **5** | **NC** | No Connection | | **6** | **Vcc** | Power Supply (3.3V) | --- ### 4. Application Areas The M3V11T2J-R is designed for high-precision applications where frequency synchronization is required: * **Networking:** Synchronous Ethernet and base stations. * **Phase-Locked Loops (PLLs):** Used to lock the frequency to an external reference. * **Broadcasting:** Digital video equipment requiring low jitter. * **Telecommunications:** SONET/SDH equipment. ---
