The **MV15T2CD-R** is a high-performance **Voltage Controlled Crystal Oscillator (VCCO / VCXO)**, typically manufactured by companies like CTS or similar frequency control specialists. It is designed for precision timing and frequency modulation in telecommunications and data processing hardware. --- ### 1. Key Technical Specifications The part number follows a specific nomenclature. Below is a breakdown of the standard technical parameters associated with this series: | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Supply Voltage ($V_{cc}$)** | Typically 3.3V or 5.0V | | **Output Type** | CMOS / HCMOS | | **Frequency Range** | 1.0 MHz to 160 MHz (varies by model) | | **Package Type** | Surface Mount (SMD) | | **Package Size** | 5.0mm x 7.0mm (standard for MV series) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Functional Characteristics The "VC" in VCXO indicates that the output frequency can be adjusted by an external control voltage. * **Frequency Pulling:** This part allows for "pullability," meaning you can fine-tune the output frequency by applying a voltage to the Control Voltage pin. * **Low Jitter:** It is designed for low phase noise, making it suitable for clock recovery and frequency synthesis. * **RoHS Compliant:** The "-R" suffix usually denotes compliance with RoHS (Restriction of Hazardous Substances) standards. --- ### 3. Pin Configuration (Typical) Most 6-pad SMD VCXOs in this series follow this layout: | Pin # | Function | Description | | :--- | :--- | :--- | | 1 | **$V_c$** | Control Voltage (Frequency Tuning) | | 2 | **E/D** | Enable/Disable (Tristate function) | | 3 | **GND** | Ground | | 4 | **Output** | Clock Signal Output | | 5 | **N/C** | No Connection | | 6 | **$V_{cc}$** | Supply Voltage | --- ### 4. Applications The MV15T2CD-R is commonly integrated into the following systems: * **Phase-Locked Loops (PLLs):** Used as the tunable element in a clock-tracking circuit. * **Networking Gear:** Switches, routers, and base stations. * **Broadcasting:** Video/audio synchronization equipment. * **Test & Measurement:** High-speed data acquisition systems. --- ### 5.
