The **MHO+46FCD-R** is a specific part number typically associated with **Temperature-Compensated Crystal Oscillators (TCXO)**, often produced by manufacturers like MtronPTI. These components are critical in telecommunications and high-precision timing circuits. --- ### 1. Technical Specifications Overview The part number follows a specific nomenclature that defines its electrical characteristics: | Feature | Specification Details | | :--- | :--- | | **Component Type** | TCXO (Temperature Compensated Crystal Oscillator) | | **Package Style** | 14-pin DIP (Dual In-line Package) or Surface Mount Equivalent | | **Output Type** | Typically HCMOS/TTL Compatible | | **Supply Voltage** | Usually +5.0V or +3.3V (Varies by sub-model) | | **Frequency Stability** | High precision, often within ±1.0ppm to ±2.5ppm | | **Operating Temp** | Typically -40°C to +85°C (Industrial Grade) | --- ### 2. Key Internal Components The "MHO" series integrates several electronic sections into one package: * **Quartz Crystal:** The primary resonator providing the base frequency. * **Compensation Network:** A thermistor-based circuit that senses temperature changes and adjusts the capacitance to keep the frequency stable. * **Varactor Diode:** Used to "pull" the frequency slightly to counteract temperature drift. * **Buffer Amplifier:** Ensures the output signal is strong enough to drive subsequent logic gates (CMOS/TTL) without loading the crystal. --- ### 3. Pinout Configuration (Standard 14-pin DIP style) While you should always consult the specific datasheet, the standard layout for this series is: ```text Pin 1: N/C or Voltage Control (V_con) Pin 7: Case Ground Pin 8: Output (Clock Signal) Pin 14: Supply Voltage (Vcc) ``` --- ### 4. Common Applications Due to its high stability compared to standard clocks, the MHO+46FCD-R is found in: 1. **Wireless Base Stations:** Maintaining sync between mobile networks. 2. **GPS Receivers:** Precision timing for satellite signal locking. 3. **Network Switches:** Ensuring high-speed data packets remain synchronized. 4. **Test Equipment:** Frequency counters and signal generators. --- ### 5. Part Number Decoding (Typical) * **MHO:** Series Prefix (MtronPTI High-Stability series). * **46:** Package/Format code. * **FCD:** Specific frequency stability and temperature range mapping. * **-R:** RoHS Compliant (Lead-free).
