Based on the part number **M5R14THJ-R**, this component is a high-performance **Crystal Oscillator** manufactured by **MtronPTI**. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ## 1. Component Overview The M5R series consists of **TCXO (Temperature Compensated Crystal Oscillators)** or high-stability clock oscillators designed for applications requiring precision timing in compact form factors. ### Key Specifications | Parameter | Typical Value / Range | | :--- | :--- | | **Output Type** | HCMOS / TTL Compatible | | **Package Style** | 9x14 mm J-Lead (Surface Mount) | | **Frequency Range** | 1.000 MHz to 150.000 MHz (Specific to ordering) | | **Operating Voltage** | 5.0V (Standard for M5R series) | | **Stability** | ±2.5 ppm to ±100 ppm (Depending on grade) | --- ## 2. Part Number Deciphering To understand the "M5R14THJ-R" suffixing: * **M5R**: Represents the product series (5.0V, 9x14 mm J-lead package). * **14**: Usually refers to the package size/code (14-pin DIP footprint compatible, though often 4 pads are used). * **T**: Denotes the Temperature Stability class. * **H**: Often represents the Symmetry/Duty Cycle (e.g., 40/60% or 45/55%). * **J**: Refers to the Tri-state Enable/Disable function (Pin 1 logic control). * **-R**: Indicates **RoHS Compliance** (Lead-free). --- ## 3. Pin Configuration The M5R14 series typically follows a standard 4-pin layout within a J-lead carrier: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Tri-state / NC | High or Open = Output Active; Low = High Impedance | | **7** | Ground | Case Ground and Supply Return | | **8** | Output | The generated clock signal (HCMOS/TTL) | | **14** | Vdd | Positive Supply Voltage (+5.0V) | --- ## 4. Typical Applications Because of its high stability and J-lead design (which provides excellent solder joint stress relief), this part is commonly used in: * **Telecommunications**: Networking switches and routers. * **Industrial Control**: Timing for embedded microprocessors. * **Test & Measurement**: Signal generators and frequency counters. * **Legacy Systems**: Replacement for full-size 14-pin DIP oscillators in high-reliability environments. --- ## 5. Technical Considerations * **Bypassing**: It is highly recommended to place a **0.01µF to 0.1µF ceramic capacitor** as close to Pin 14 (Vdd) and Pin 7 (GND) as possible to minimize noise. * **Load Capacitance**: Standard HCMOS loads are usually **15pF to 50pF**. Exceeding the rated load can degrade rise/fall times and increase power consumption.
