The **M3V13T1J-R** is a high-performance **VCXO (Voltage Controlled Crystal Oscillator)** manufactured by Jonson (or similar precision frequency control providers). It is designed for applications requiring precise frequency tuning via an external control voltage. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the M3V series (specifically the T1J-R configuration): | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Package Size** | 3.2 x 5.0 mm (SMD) | | **Output Type** | HCMOS / TTL | | **Supply Voltage (Vcc)** | +3.3 VDC | | **Frequency Stability** | ±50 ppm (Typical for '1' code) | | **Operating Temperature** | -40°C to +85°C ('J' code) | | **Pullability (Range)** | ±100 ppm Minimum | | **RoHS Status** | Compliant (indicated by '-R') | --- ### 2. Part Number Breakdown Understanding the suffix codes helps in identifying the specific electronic behavior of the unit: * **M3V**: Series designation (3.2x5.0mm Voltage Controlled Oscillator). * **1**: Frequency Stability code (typically denotes ±50ppm). * **3**: Supply Voltage (denotes 3.3V). * **T**: Packaging (Tape & Reel). * **1**: Pullability Range (typically ±100ppm). * **J**: Temperature Range code (-40°C to +85°C). * **R**: RoHS Compliant. --- ### 3. Pin Configuration Standard 6-pad layout for the 3.2x5.0mm package: 1. **V_control**: Voltage input used to adjust the output frequency. 2. **Enable/Disable (OE)**: High or floating allows output; Low sets output to high impedance. 3. **Ground**: Case and circuit ground. 4. **Output**: The HCMOS frequency signal. 5. **No Connect (NC)**: Often used for internal testing or left floating. 6. **Vcc**: Positive power supply (+3.3V). --- ### 4. Applications The M3V13T1J-R is commonly utilized in circuits where a clock signal must be "locked" or synchronized to an external reference: * **Phase Locked Loops (PLL):** Used as the adjustable frequency source. * **Networking:** SONET/SDH, Ethernet synchronization. * **Broadcasting:** Video/Audio clock recovery. * **Telecommunications:** Base stations and digital switching.
