The **M3V15V2CJ-R** is a specific part number belonging to a series of **Voltage Controlled Crystal Oscillators (VCXO)**, typically manufactured by suppliers like **MtronPTI**. These components are essential in telecommunications and data processing for frequency synchronization. --- ### 1. General Specifications Based on the standard nomenclature for this series, here is the breakdown of the electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Type** | Surface Mount (SMD) | | **Standard Frequency Range** | 1.0000 MHz to 52.0000 MHz (Specific to ordering) | | **Supply Voltage (Vcc)** | +3.3 VDC (indicated by the '3' code) | | **Output Type** | CMOS / HCMOS compatible | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Key Features and Functions * **Voltage Control (V_c):** Unlike a fixed oscillator, this part allows the output frequency to be adjusted (pulled) by applying a small external DC voltage. This is critical for Phase-Locked Loops (PLLs). * **Low Jitter:** Designed for high-speed data applications where timing precision is vital to prevent data errors. * **Tri-state Function:** Includes an enable/disable pin (Control Pin 2 or 5 depending on footprint) that allows the output to be placed in a high-impedance state for testing or power saving. * **Stability:** Offers tight frequency stability over temperature, usually measured in parts per million (ppm). --- ### 3. Pin Configuration (Typical 6-Pad Layout) The "CJ" suffix often refers to a standard 6-pad 5x7mm or 3.2x5mm ceramic package. | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | **Voltage Control** | Input voltage to adjust frequency | | **2** | **Enable/Disable** | Logic high for output; logic low for high-Z | | **3** | **Case Ground** | Connection to 0V / Ground | | **4** | **Output** | CMOS/HCMOS Frequency Signal | | **5** | **N/C or NC** | No internal connection | | **6** | **Supply Voltage** | +3.3V Input | --- ### 4. Common Applications * **Networking:** Synchronous Ethernet (SyncE) and SONET/SDH equipment. * **Wireless Base Stations:** Frequency synthesis and clock recovery. * **Broadcasting:** Video processing and digital audio synchronization. * **Instrumentation:** Signal generators and frequency counters. --- ### 5. Part Number Decoding (Typical) * **M3V:** 3.3V VCXO Series. * **15:** Pullability (e.g., ±150 ppm or ±50 ppm depending on the specific datasheet revision). * **V:** Voltage Control capability. * **2:** Stability code (e.g., ±25 ppm). * **CJ:** Operating Temperature and Package code. * **R:** RoHS Compliant / Tape and Reel packaging.
