The **MHO+68FAG-R** is a specific part number belonging to a series of high-precision, oven-controlled, or temperature-compensated crystal oscillators (typically associated with the **MtronPTI** brand). This component is designed for high-reliability applications where frequency stability is critical. --- ### 1. Key Technical Specifications Below are the typical technical parameters associated with this class of electronic components: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Frequency Range** | Usually fixed (varies by sub-code, often MHz range) | | **Output Type** | CMOS / TTL Compatible | | **Voltage Supply** | 3.3V or 5.0V (Standard) | | **Package Style** | Full-size or Half-size DIP (14-pin or 8-pin footprint) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Part Number Breakdown The alphanumeric code provides specific details about the construction and performance of the part: * **MHO:** This prefix generally identifies the series name, often signifying a "Metal High-reliability Oscillator" or a specific frame size used by MtronPTI. * **68:** This typically represents the specific stability and temperature range code (e.g., ±50ppm or ±25ppm stability). * **F:** Usually indicates the output type (e.g., Fixed Frequency or specific CMOS levels). * **A:** Often represents the duty cycle or the symmetry of the output wave (e.g., 40/60% or 45/55%). * **G:** Can indicate the internal pin connection configuration (which pins are Enable/Disable). * **-R:** Confirms the part is **RoHS compliant** (Lead-free). --- ### 3. Physical Features & Applications #### Physical Attributes * **Hermetic Sealing:** The part is housed in a metal "can" package that is resistance-welded to protect the quartz crystal from moisture and atmospheric pressure changes. * **Through-Hole Mounting:** Designed for PCB mounting via pins, providing high mechanical stability against vibration. #### Common Applications 1. **Telecommunications:** Used in base stations and networking hardware for precise clocking. 2. **Industrial Control:** Providing timing for microprocessors in harsh environments. 3. **Measurement Equipment:** High-end oscilloscopes and frequency counters. 4. **Aerospace/Defense:** Legacy systems requiring stable timing over wide temperature fluctuations. --- ### 4. Schematic Example (Typical Pinout) The standard 14-pin DIP footprint (where only 4 pins are usually used) follows this logic: ```text Pin 1: N/C or Tri-state (Enable/Disable) Pin 7: Case Ground Pin 8: Output Signal Pin 14: Vcc (+3.3V or +5V) ```
