The **MHO364TAG-R** is a specific electronic component, typically categorized as a **High-Stability Oven Controlled Crystal Oscillator (OCXO)** or a high-precision timing module, often manufactured by companies like MtronPTI. Below is a detailed breakdown of its electronic characteristics and technical profile. --- ### 1. General Specifications The "MHO" series generally refers to high-reliability oscillators designed for telecommunications and industrial applications where frequency stability is critical. | Feature | Description | | :--- | :--- | | **Component Type** | Oven Controlled Crystal Oscillator (OCXO) | | **Package Style** | Through-hole (DIP) or Surface Mount (depending on suffix) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage** | Typically 3.3V or 5.0V DC | | **Frequency Range** | Usually fixed between 1 MHz and 160 MHz | --- ### 2. Key Electronic Features The "TAG-R" suffix often denotes specific environmental and RoHS compliance standards. #### A. Temperature Stability The core of this part is the "Oven" (the heater circuit). It maintains the internal quartz crystal at a constant temperature (the "turnover point") to prevent frequency drift caused by external temperature changes. * **Stability:** Often rated in the parts-per-billion (ppb) range. #### B. Phase Noise & Jitter Designed for high-speed data transmission, these parts exhibit: * **Low Phase Noise:** Minimal frequency fluctuations near the carrier signal. * **Low Jitter:** Precise timing intervals, essential for reducing bit-error rates in digital systems. #### C. Control Voltage (Vcxo Function) Many models in this series include an **Electronic Frequency Control (EFC)** pin. This allows the user to apply a small voltage to "fine-tune" the frequency to compensate for aging over several years. --- ### 3. Pinout Configuration (Standard MHO Series) While you should always consult the specific datasheet for the **364TAG-R** variant, the standard 4-pin or 14-pin DIP configuration usually follows this logic: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | Vc (EFC) | Control voltage for frequency adjustment. | | **7/8** | Case Ground | Common ground for the circuit. | | **8/11** | Output | The generated clock signal. | | **14** | Vcc | Power supply input. | --- ### 4. Typical Applications Due to its high precision, the MHO364TAG-R is found in: * **Base Stations:** LTE/5G cellular infrastructure. * **Test Equipment:** Frequency counters and signal generators. * **SatCom:** Satellite ground station synchronization. * **Network Switches:** High-speed Ethernet timing. --- ### 5. Compliance * **RoHS (-R):** The "R" in the part number typically signifies **RoHS Compliance**, meaning the part is lead-free and meets environmental safety regulations for hazardous substances.
