The **M7S65TCJ-R** is a specific electronic component, typically categorized as a high-precision **SMD (Surface Mount Device) Crystal Oscillator**. These components are critical in electronics for providing a stable clock signal to microprocessors and digital circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The M7S series is generally manufactured by companies like **NDK (Nihon Dempa Kogyo)** or similar high-reliability frequency control suppliers. | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | SPXO (Simple Packaged Crystal Oscillator) | | **Package Size** | 7.0 x 5.0 mm (Standard SMD 7050 Package) | | **Output Type** | CMOS / TTL | | **Mounting Type** | Surface Mount (SMD) | | **RoHS Status** | Compliant (Lead-Free) | --- ### 2. Key Electronic Features The part number suffix and series designation reveal the functional capabilities of the device: * **Frequency Stability:** These oscillators are designed to maintain a consistent frequency across a wide temperature range, usually measured in parts per million (PPM). * **Low Phase Jitter:** Crucial for high-speed data transmission to prevent errors in timing. * **Enable/Disable Function (Tri-state):** Pin 1 usually supports a "Standby" or "Output Enable" function, allowing the system to reduce power consumption by turning off the clock signal when not needed. * **Operating Voltage:** Typically operates at standard logic levels (e.g., 3.3V or 5.0V), though the specific suffix "CJ-R" defines the exact voltage tolerance. --- ### 3. Pin Configuration (7050 Package) Standard 4-pin configuration for this form factor: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Standby / OE | High or Open: Output active; Low: High impedance | | **2** | GND | Ground connection | | **3** | Output | Clock signal output | | **4** | Vcc | Supply voltage | --- ### 4. Typical Applications The M7S65TCJ-R is found in industrial and consumer electronics that require a robust timing source: * **Networking Gear:** Routers, switches, and modems. * **Computing:** Motherboards and peripheral controllers. * **Industrial Control:** PLC units and automated sensors. * **Audio/Video:** Digital Signal Processors (DSPs) requiring stable sampling rates. --- ### 5. Part Number Breakdown (Naming Logic) While exact manufacturer coding varies slightly, the "R" suffix typically indicates **Tape & Reel** packaging, meaning the parts are supplied on a reel for automated "Pick and Place" assembly machines.
