The **MHO317FAG-R** belongs to the category of high-precision electronic components, specifically categorized as an **Oven Controlled Crystal Oscillator (OCXO)** or a high-stability **TCXO** (Temperature Compensated Crystal Oscillator) depending on the specific series iteration. It is manufactured by providers like **MtronPTI**. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. Key Technical Specifications The following table outlines the general performance parameters typical for the MHO series components: | Parameter | Typical Value / Range | | :--- | :--- | | **Nominal Frequency** | Fixed frequency (e.g., 10MHz, 20MHz, etc.) | | **Frequency Stability** | ±0.1 ppm to ±1.0 ppm (Temperature dependent) | | **Supply Voltage (Vcc)** | 3.3V or 5.0V DC | | **Output Type** | CMOS / HCMOS | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Type** | 4-Pin or 6-Pin DIP (Through-Hole) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Functional Description The part is designed to provide a highly stable clock signal for digital circuits. The "MHO" designation usually refers to a specific metal-can package style that provides electromagnetic interference (EMI) shielding. * **Internal Crystal:** Uses a high-quality quartz crystal blank cut for minimal frequency drift. * **Compensation Circuitry:** Includes internal circuitry to correct for frequency deviations caused by changes in the ambient temperature. * **The "-R" Suffix:** This strictly denotes **RoHS Compliance**, meaning the part is manufactured without lead, mercury, cadmium, or other hazardous substances. --- ### 3. Pin Configuration (Typical) For the standard DIP package used by this series, the pinout is usually as follows: 1. **Pin 1 (Vcon / NC):** Voltage Control (for tuning) or No Connection. 2. **Pin 2 (GND):** Case and Circuit Ground. 3. **Pin 3 (Output):** The clock signal output (Square wave). 4. **Pin 4 (Vcc):** Positive Power Supply input. --- ### 4. Common Applications Due to its high stability, the MHO317FAG-R is commonly found in: * **Telecommunications:** Base stations and synchronization hardware. * **Test & Measurement:** Frequency counters and signal generators. * **Networking:** Routers and switches requiring precise timing for data packets. * **Industrial Control:** Systems operating in environments with fluctuating temperatures.
