The **M3V23V1AJ-R** is a specific part number for a **Surface Mount (SMD) Quartz Crystal Oscillator**. It is commonly used in telecommunications, networking, and consumer electronics to provide a precise clock signal for integrated circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications Based on the standard naming convention for this series (often associated with manufacturers like MtronPTI), the specifications are typically as follows: | Parameter | Details | | :--- | :--- | | **Component Type** | Voltage Controlled Crystal Oscillator (VCXO) or Standard XO | | **Package Type** | SMD (Surface Mount Device) | | **Package Size** | 3.2mm x 5.0mm (Standard J-Lead or Ceramic) | | **Output Type** | CMOS / HCMOS | | **Input Voltage ($V_{dd}$)** | 3.3V DC (Typical for the '3V' designation) | | **RoHS Status** | Compliant (Lead-Free) | --- ### 2. Pin Configuration The device usually features 4 or 6 pads. For a standard 4-pad configuration: 1. **Pin 1 (VC or NC):** Control Voltage (for VCXO) or No Connection. 2. **Pin 2 (GND):** Case Ground and Supply Return. 3. **Pin 3 (Output):** The generated frequency signal. 4. **Pin 4 ($V_{dd}$):** Power Supply Input. --- ### 3. Key Electronic Characteristics * **Frequency Stability:** Usually ranges from $\pm25ppm$ to $\pm100ppm$, ensuring the timing remains consistent across temperature variations. * **Operating Temperature:** Typically rated for $-40^\circ C$ to $+85^\circ C$ (Industrial Grade). * **Low Jitter:** Designed to provide a "clean" signal with minimal timing noise, which is critical for high-speed data transmission. * **Tri-state Function:** Often includes an Enable/Disable function on Pin 1 to reduce power consumption when the clock is not needed. --- ### 4. Typical Applications The M3V23V1AJ-R is found in circuits requiring stable frequency references: * **Network Switches/Routers:** Syncing data packets. * **Wireless Communication:** Base stations and RF modules. * **Embedded Systems:** Providing the heartbeat for Microcontrollers (MCUs) or FPGAs. * **Phase-Locked Loops (PLL):** Used as a reference frequency in frequency synthesis. ---
