Technical Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Frequency Range** | Typically fixed (Check specific datasheet for MHz) | | **Output Type** | HCMOS / TTL | | **Supply Voltage (Vcc)** | +5.0V DC (Standard for the MHO series) | | **Package Style** | 14-pin DIP (Full size) or 8-pin DIP (Half size) | | **Stability** | ±100ppm to ±25ppm (depending on suffix) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ### 2. Part Number Breakdown (Nomenclature) The part number can be decoded to understand its specific environmental and electrical ratings: * **MHO:** Series designation (Metal Hermetic Oscillator). * **+:** Denotes RoHS compliance (Lead-free). * **63:** Represents the specific stability and temperature range combination. Usually, "6" indicates the operating temperature and "3" indicates the frequency stability. * **F:** Refers to the symmetry/duty cycle of the waveform (typically 40/60% or 45/55%). * **B:** Refers to the Tri-state (Enable/Disable) function on Pin 1. * **G:** Indicates the "Full Size" 14-pin DIP package layout. * **-R:** Confirms RoHS Compliance. --- ### 3. Key Electronic Features * **Hermetic Sealing:** The internal quartz crystal is sealed in a metal package with resistance welding. This protects the component from atmospheric moisture and contaminants, ensuring long-term frequency aging stability. * **Tri-state Functionality:** This allows the output to be placed in a high-impedance state, effectively "disconnecting" the oscillator from the bus without powering it down. * **Low Jitter:** Designed for clocking microprocessors, DSPs, and high-speed data communication interfaces where timing precision is critical. --- ### 4. Typical Applications The MHO+63FBG-R is commonly found in: 1. **Industrial Control Systems:** PLC units and factory automation. 2. **Telecommunications:** Base stations and networking hardware. 3. **Legacy Computing:** Replacement parts for older motherboards or timing circuits requiring 5V logic. 4. **Test & Measurement:** Oscilloscopes and signal generators. --- ### 5. Pin Configuration (Full-Size DIP) | Pin Number | Function | | :--- | :--- | | **1** | NC (No Connection) or Tri-state Enable | | **7** | Case Ground | | **8** | Output Signal | | **14** | Vcc (+5.0V) |
