The **MHO+63FAAD-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is part of the MHO+ series, which is specifically designed for high-reliability applications requiring high frequencies and stability. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | CMOS / TTL | | **Supply Voltage** | 3.3V DC | | **Package Style** | 14-pin DIP (Full Size) | | **Stability** | ±100 ppm (standard for this series) | | **Operating Temperature** | 0°C to +70°C | | **RoHS Status** | RoHS Compliant (-R suffix) | --- ### 2. Key Electronic Features * **Tri-State Functionality:** This part typically includes an output enable/disable function (Pin 1), allowing the output to be placed in a high-impedance state for testing or power management. * **Hermetically Sealed:** The internal crystal is housed in a metal DIP package, protecting it from environmental moisture and contaminants. * **Low Jitter:** Designed for timing applications where phase noise and clock jitter must be minimized to ensure data integrity. * **Through-Hole Mounting:** As a 14-pin DIP package, it is intended for through-hole PCB assembly, which is robust for high-vibration environments. --- ### 3. Pin Configuration (Standard 14-pin DIP) Though it occupies a 14-pin footprint, usually only 4 pins are electrically connected: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | Enable/Disable control | | **7** | Ground | Circuit ground | | **8** | Output | Frequency signal output | | **14** | Vcc | +3.3V Power supply | --- ### 4. Common Applications Due to its reliability and standard footprint, the MHO+63FAAD-R is used in: * **Networking Hardware:** Switches, routers, and hubs. * **Industrial Controls:** High-reliability automation systems. * **Legacy Computing:** Replacement parts for older industrial motherboards or timing circuits. * **Test and Measurement:** Signal generators and oscilloscopes.
