Technical Specifications Below are the primary technical parameters generally associated with this part number: | Feature | Specification (Typical) | | :--- | :--- | | **Type** | Oven Controlled Crystal Oscillator (OCXO) or Temperature Compensated (TCXO) | | **Frequency Range** | Usually fixed (e.g., 10MHz, 20MHz, or custom) | | **Package Style** | Through-Hole (DIP-14 or similar footprint) | | **Operating Voltage** | 3.3V or 5.0V DC | | **Output Type** | CMOS / HCMOS | | **Frequency Stability** | ±0.1 ppm to ±1.0 ppm (depending on temperature range) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | --- ## 2. Key Internal Components The "MHO" series typically integrates several electronic sub-systems within its metal casing: ### A. The Quartz Crystal The heart of the unit. It is a precision-cut quartz wafer that vibrates at a specific frequency when an electrical current is applied (Piezoelectric effect). ### B. Compensation Circuitry The **"TCG"** suffix often indicates **Temperature Compensation**. It uses a thermistor network or a digital compensation IC to adjust the frequency as the ambient temperature changes, preventing "frequency drift." ### C. Buffer Amplifier An internal transistor-based circuit that strengthens the oscillation signal so it can drive other components on the PCB without losing signal integrity. --- ## 3. Applications The MHO366TCG-R is commonly found in high-reliability industrial electronics: 1. **Base Stations:** Used in cellular infrastructure to sync data packets. 2. **Test Equipment:** Found in frequency counters and signal generators. 3. **GPS Receivers:** Provides the stable "heartbeat" required for satellite signal acquisition. 4. **Network Switches:** Ensures high-speed data transmission remains synchronized across ports. --- ## 4. Pin Configuration (Typical DIP-14) * **Pin 1:** Control Voltage (VC) or No Connect (NC). * **Pin 7:** Ground (GND). * **Pin 8:** Output (Frequency Signal). * **Pin 14:** Supply Voltage (Vcc).
