The **M3V13V1CJ-R** is a specific type of electronic component categorized as a **Voltage Controlled Crystal Oscillator (VCXO)**. It is manufactured by **Microchip Technology** (formerly under the Vectron International brand). --- ## 1. Core Technical Specifications This component is designed for precise frequency generation where the output frequency can be slightly adjusted (pulled) by an external control voltage. | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package / Case** | 6-pin SMD (Surface Mount Device), 3.2mm x 5.0mm | | **Supply Voltage ($V_{dd}$)** | 3.3V | | **Output Type** | CMOS / LVCMOS | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | Generally ±50 ppm or ±25 ppm (varies by sub-model) | | **Pullability (APR)** | Minimum ±100 ppm | --- ## 2. Pin Configuration The M3V series typically utilizes a standard 6-pin layout for miniature SMD oscillators: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | $V_c$ | **Control Voltage:** Input used to adjust the output frequency. | | **2** | E/D | **Enable/Disable:** Allows the output to be turned on or off. | | **3** | GND | **Ground:** Circuit common. | | **4** | Output | **Frequency Out:** The generated clock signal. | | **5** | N/C | **No Connection:** Reserved for internal use. | | **6** | $V_{dd}$ | **Supply Voltage:** Positive power input (3.3V). | --- ## 3. Key Functional Features * **Voltage Tuning:** Unlike fixed oscillators, the "V" in VCXO allows for fine-tuning. By changing the voltage on Pin 1, the user can compensate for aging or synchronize with other signals. * **Low Phase Jitter:** Engineered for high-speed data applications where timing precision is critical to reduce data transmission errors. * **CMOS Output:** Provides a rail-to-rail square wave compatible with most modern microcontrollers (MCUs) and FPGAs. * **RoHS Compliant:** The "-R" suffix typically denotes compliance with RoHS (Restriction of Hazardous Substances) standards. --- ## 4. Common Applications Due to its ability to be "steered" by a control voltage, this part is commonly found in: 1. **Phase-Locked Loops (PLLs):** Used to synchronize clock signals in communication systems. 2. **Broadcasting Equipment:** Digital video and audio synchronization. 3. **Networking:** SONET/SDH, Ethernet, and fiber optic modules. 4. **Frequency Synthesis:** Generating precise frequencies derived from a reference signal.
