The **M3V23TAJ-R** is a specific part number belonging to the **M3V** series of Voltage Controlled Crystal Oscillators (VCXO), typically manufactured by **MtronPTI**. These components are critical for frequency control and timing in telecommunications and networking equipment. --- ### 1. General Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Feature | Specification | Description | | :--- | :--- | :--- | | **Component Type** | VCXO | Voltage Controlled Crystal Oscillator | | **Package Size** | 5.0 x 7.0 mm | Standard 6-pad SMD Ceramic package | | **Output Type** | HCMOS / TTL | High-speed CMOS compatible output | | **Voltage Supply** | 3.3V | Standard operating voltage (typified by the '3' or 'V') | | **Control Voltage** | 0.3V to 3.0V | Range used to "pull" or tune the frequency | --- ### 2. Key Electronic Parameters This part is designed for precision and stability. Below are the typical electronic attributes for this series: * **Frequency Range:** Usually available from 1.000 MHz to 160.000 MHz (exact frequency is specified in the full long-form part number). * **Frequency Pullability:** Typically ±100 ppm (parts per million). This allows the circuit to adjust the clock speed slightly to synchronize with other signals. * **Stability:** Often rated at ±25ppm to ±50ppm depending on the specific temperature grade. * **Phase Jitter:** Low jitter performance, essential for high-speed data transmission to prevent bit errors. --- ### 3. Pin Configuration (6-Pad SMD) The "TAJ" suffix often refers to the specific pinout and temperature configuration. A standard 6-pad VCXO like this usually follows this layout: | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | **V_control** | Voltage applied here changes the output frequency. | | **2** | **Tristate / NC** | Enable/Disable function (High = Output, Low = High Impedance). | | **3** | **GND** | Circuit Ground. | | **4** | **Output** | The HCMOS square wave signal. | | **5** | **NC** | No connection (internal). | | **6** | **Vcc** | Supply Voltage (3.3V). | --- ### 4. Typical Applications Because of its ability to "lock" onto other frequencies via the control voltage pin, the M3V23TAJ-R is used in: * **Phase-Locked Loops (PLLs):** For frequency synthesis. * **Clock Recovery:** In fiber optic and ethernet systems. * **Base Stations:** For wireless infrastructure synchronization. * **Digital Video:** Maintaining sync in broadcast equipment.
