The **MHO+52FAAG-R** is a high-performance **Crystal Oscillator** manufactured by MtronPTI. This specific series is known for its reliability in telecommunications and data processing applications. --- ### 1. Component Overview This part belongs to the **MHO+ Series**, which consists of quartz crystal oscillators housed in a 14-pin DIP (Dual In-line Package) metal enclosure. The "R" suffix typically denotes RoHS (Restriction of Hazardous Substances) compliance. ### 2. Technical Specifications Below are the primary electrical and physical characteristics: | Feature | Specification | | :--- | :--- | | **Package Type** | 14-pin DIP (Metal Case) | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | 5.0 VDC | | **Frequency Stability** | Usually ±25ppm to ±100ppm (depending on sub-code) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Duty Cycle** | 40/60% to 45/55% | | **Termination** | Through-hole | --- ### 3. Key Electronic Features * **Hermetically Sealed:** The metal package is vacuum-sealed or filled with nitrogen to protect the quartz crystal from moisture and environmental contaminants, ensuring long-term frequency stability. * **Tri-state Functionality:** The "FA" designation often indicates specific enable/disable logic, allowing the output to enter a high-impedance state, which is useful for testing or power-saving. * **Low Phase Jitter:** Designed for timing-critical applications where signal integrity is paramount. ### 4. Pin Configuration (Standard 14-pin DIP) Though it has 14 pins, most are used for structural support. The active pins are typically: 1. **Pin 1:** N/C (No Connection) or Tri-state Control. 2. **Pin 7:** Case Ground ($GND$). 3. **Pin 8:** Output Signal. 4. **Pin 14:** Supply Voltage ($+5V$). --- ### 5. Common Applications * **Networking:** Routers, switches, and gateways. * **Industrial Control:** PLCs and automation timing. * **Legacy Computing:** Motherboards or embedded systems requiring a 5V clock source. * **Test Equipment:** Oscilloscopes and signal generators.
