The **MHO+53FBG-R** is a specific model within the series of high-precision, oven-controlled, or temperature-compensated crystal oscillators (typically part of the MHO series by manufacturers like MtronPTI). These components are designed for high-reliability applications requiring stable frequency references. --- ### 1. Component Specifications & Breakdown Based on the standard nomenclature for this series, here is the technical breakdown of the part: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Crystal Oscillator | Provides a stable clock signal for digital circuits. | | **Package Style** | 14-pin DIP (Full Size) | A metal "can" package that provides superior EMI shielding. | | **Output Type** | HCMOS / TTL | Compatible with standard logic levels. | | **Supply Voltage** | 5.0V DC | Standard operating voltage for the "5" designation in the series. | | **Frequency Stability** | ±100ppm to ±25ppm | High precision over the operating temperature range. | | **Operating Temp** | -40°C to +85°C | Industrial grade (indicated by the 'G' or 'R' suffixes). | ### 2. Key Features * **Hermetically Sealed:** The metal housing is vacuum-sealed or filled with inert gas to prevent environmental moisture from affecting the quartz crystal. * **Low Phase Noise:** Designed to minimize "jitter," which is critical for high-speed communication and data processing. * **RoHS Compliant:** The "R" suffix typically denotes compliance with lead-free environmental standards. * **Tri-state Functionality:** Often includes an enable/disable pin (Pin 1) to allow the output to go into a high-impedance state for power saving or bus sharing. ### 3. Pin Configuration (Typical 14-Pin DIP) Even though the package is large, usually only 4 pins are electrically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | No connection or Output Enable/Disable. | | **7** | Ground | Case ground and circuit return. | | **8** | Output | The generated square wave frequency. | | **14** | Vcc | +5.0V Power Supply. | ### 4. Common Applications Due to its robust metal packaging and stability, the MHO+53FBG-R is commonly found in: * **Networking Equipment:** Routers, switches, and gateways. * **Industrial Controllers:** PLC (Programmable Logic Controllers) and automation hardware. * **Legacy Computing:** Replacement parts for older industrial motherboards or timing circuits. * **Test & Measurement:** Oscilloscopes and signal generators. ---
