The **MHO+15TAG-R** is a high-performance **Crystal Oscillator** (specifically a Clock Oscillator) manufactured by **MtronPTI**. It belongs to the MHO series, which is known for its reliability in industrial and communication applications. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the MHO+15TAG-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Output Type** | HCMOS / TTL | | **Frequency Range** | Typically 1.000 MHz to 125.000 MHz | | **Supply Voltage (Vcc)** | 5.0 Volts (±10%) | | **Package Style** | 14-pin DIP (Full Size), Through-hole | | **Frequency Stability** | ±100 ppm (Standard for the "1" code) | | **Operating Temperature** | 0°C to +70°C (Standard) | | **Duty Cycle** | 40/60% or 45/55% | --- ### 2. Breakdown of the Part Number The alphanumeric code follows MtronPTI’s specific nomenclature: * **MHO:** Series designation (Metal Can, High Output/High Speed). * **+:** Lead-free / RoHS compliant indicator. * **1:** Frequency Stability code (typically represents ±100ppm). * **5:** Symmetry/Duty Cycle code (standard 40/60%). * **T:** Temperature Range (T usually indicates standard 0°C to +70°C). * **A:** Output Load (Standard HCMOS/TTL). * **G:** Tri-state Enable/Disable function on Pin 1. * **-R:** Denotes RoHS compliance and specific packaging/revision requirements. --- ### 3. Key Features and Applications #### Features * **Tri-state Functionality:** Allows the output to be placed in a high-impedance state, which is useful for testing or power management. * **Hermetically Sealed:** The metal "can" package protects the internal quartz crystal from environmental moisture and contaminants. * **Low Jitter:** Designed for timing-critical digital circuits. #### Applications * **Microprocessor Clocks:** Providing the base heartbeat for CPUs and MCUs. * **Networking Gear:** Used in routers, switches, and modems. * **Industrial Control:** Reliable timing for PLCs and automated machinery. * **Legacy Hardware:** The 14-pin DIP format is common in older equipment maintenance and robust industrial designs. --- ### 4. Pin Configuration (14-Pin DIP) While it has a 14-pin footprint, only 4 pins are typically connected: | Pin Number | Function | | :--- | :--- | | **Pin 1** | Tri-state (Enable/Disable) | | **Pin 7** | Case Ground (GND) | | **Pin 8** | Output (Signal) | | **Pin 14** | Supply Voltage (+5V) |
