The **M7S36TCJ-R** is a specific part number belonging to the **M7S Series** of crystal oscillators, manufactured by **MtronPTI**. These components are widely used for providing precise timing signals in electronic circuits. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The M7S series consists of **HCMOS/TTL compatible** miniature surface-mount (SMD) crystal oscillators. | Feature | Specification | | :--- | :--- | | **Type** | Fixed Frequency Crystal Oscillator (XO) | | **Output Type** | HCMOS / TTL | | **Package Size** | 5.0 x 7.0 mm (standard 4-pad SMD) | | **Supply Voltage ($V_{DD}$)** | Typically 3.3V (standard for the '36' designation) | | **Operating Temperature** | Commercial or Industrial grades available | --- ### 2. Part Number Breakdown The nomenclature for MtronPTI oscillators follows a specific pattern. Here is how the **M7S36TCJ-R** is likely decoded: * **M7S**: Series identifier (5x7mm SMD, HCMOS/TTL). * **36**: Voltage code. Typically signifies a **3.3V** operating voltage. * **T**: Tri-state Enable/Disable function (allows the output to be high-impedance). * **C**: Stability code (e.g., ±100ppm, ±50ppm, or ±25ppm depending on specific datasheet revisions). * **J**: Temperature range (Commonly implies -40°C to +85°C for Industrial). * **R**: RoHS Compliant (Lead-free). --- ### 3. Pin Configuration Standard 5x7mm oscillators like the M7S series use a 4-pad layout: | Pad # | Function | Description | | :--- | :--- | :--- | | **1** | **Enable/Disable (E/D)** | High or Floating = Output Active; Low = High Impedance | | **2** | **Ground (GND)** | Circuit and Case Ground | | **3** | **Output** | Frequency signal output (Square Wave) | | **4** | **$V_{DD}$** | Power Supply Input | --- ### 4. Key Electronic Characteristics * **Frequency Range:** Usually available from 1.000 MHz to 125.000 MHz (The specific frequency is usually printed on the component body). * **Duty Cycle:** Typically 40/60% or 45/55%. * **Rise/Fall Time:** Fast switching times (typically < 5ns) to support high-speed digital logic. * **Low Jitter:** Designed for timing-sensitive applications like Ethernet, Storage Area Networks, and Microprocessors. --- ### 5.
