The **MHO+54TCG-R** is a specific part number typically associated with a **High-Frequency Crystal Oscillator (XO)**. These components are essential in digital electronics for providing a stable clock signal. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The "MHO" series is often manufactured by companies like **MtronPTI**. This specific model is a through-hole, metal-can oscillator designed for high-performance timing. | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Full Size) / 4-pins used | | **Output Type** | CMOS / TTL Compatible | | **Frequency Range** | Usually fixed (determined by specific suffix) | | **Operating Voltage** | 5.0V DC (Standard for MHO+ series) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by -R) | --- ### 2. Pinout Configuration Although it uses a 14-pin footprint, only four pins are physically present or functional. | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock frequency signal | | **14** | Vcc | +5V Power Supply | --- ### 3. Key Electronic Characteristics #### A. Frequency Stability The "54" in the part number often refers to the stability rating. In the MtronPTI nomenclature, this typically signifies a stability of **±50 ppm** (parts per million) over the operating temperature range. This ensures the digital clock remains accurate even as the device heats up. #### B. Output Waveform The device produces a **Square Wave**. Because it is CMOS/TTL compatible, it can drive logic gates directly without needing additional buffer circuitry, provided the load capacitance (typically 15pF to 50pF) is respected. #### C. The "-R" Suffix The **-R** at the end of the part number denotes **RoHS Compliance**. This means the part is manufactured without lead, mercury, cadmium, or other hazardous substances, making it suitable for modern environmental standards. --- ### 4. Common Applications * **Microprocessor Clocks:** Providing the heartbeat for CPUs and MCUs. * **Networking Gear:** Used in switches and routers for data synchronization. * **Industrial Control:** Timing for PLC (Programmable Logic Controllers). * **Legacy Systems:** Often used as a high-reliability replacement for older timing circuits in 5V logic systems.
