The **M3V26T1CJ-R** is a specific part number for a high-performance **Crystal Oscillator** manufactured by **Microchip Technology** (formerly Vectron International). It is a Voltage Controlled Crystal Oscillator (VCCO/VCXO) designed for precision timing applications. --- ### 1. Key Technical Specifications The following table highlights the primary electrical and physical characteristics of the M3V series: | Parameter | Specification | | :--- | :--- | | **Component Type** | VCXO (Voltage Controlled Crystal Oscillator) | | **Frequency Range** | Typically 1.5 MHz to 170 MHz | | **Output Logic** | CMOS / HCMOS | | **Supply Voltage ($V_{DD}$)** | +3.3 VDC | | **Package Size** | 3.2 x 5.0 mm (SMD) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Stability** | ±50 ppm (standard, varies by suffix) | | **Mounting Type** | Surface Mount (SMT) | --- ### 2. Breakdown of the Part Number The alphanumeric code provides specific details about the component's configuration: * **M3V**: The series designation (3.2 x 5.0 mm VCXO). * **26**: Represents specific stability and pullability parameters. * **T**: Operating Temperature Range (usually Industrial: -40°C to +85°C). * **1**: Supply Voltage (3.3V). * **CJ**: Output type and specific frequency control characteristics. * **R**: Tape and Reel packaging (standard for automated assembly). --- ### 3. Functional Features The M3V26T1CJ-R is characterized by several key functional blocks: 1. **Voltage Control (Pin 1):** Unlike standard fixed oscillators, this part allows the output frequency to be "tuned" or shifted slightly by applying a control voltage. This is critical for Phase Locked Loops (PLLs). 2. **Tristate Enable/Disable:** It includes an output enable function, allowing the oscillator to be disconnected from the bus for power saving or testing. 3. **Low Jitter:** Designed for high-speed data applications where timing precision is vital to prevent data errors. --- ### 4. Common Applications Due to its voltage-controlled nature and small footprint, this part is commonly found in: * **Telecommunications:** Base stations and switching equipment. * **Broadband Access:** DSLAMs and cable head-end equipment. * **Video Systems:** Digital video broadcast and processing. * **Clock Recovery:** Used in circuits that need to synchronize with an incoming data stream. ---
