The **MHO+14FCG-R** is a specific type of **Crystal Oscillator** (often categorized under Frequency Control products). It is a high-precision electronic component used to generate a stable clock signal for digital circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by manufacturers like **MtronPTI**. Below are the typical characteristics of this series: | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Package / Case** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage ($V_{cc}$)** | +5.0 VDC (Standard) | | **Stability** | Usually ±100ppm, ±50ppm, or ±25ppm (depending on sub-grade) | | **Termination** | Through-hole | | **RoHS Status** | "R" suffix indicates RoHS Compliant | --- ### 2. Breakdown of the Part Number To understand the electronic properties, we can decode the identifier: * **MHO:** Identifies the product series (MtronPTI High-Output/Standard Oscillator). * **+:** Often indicates a specific lead-free or enhanced process designation. * **14:** Refers to the **14-pin DIP footprint**. Note: In these oscillators, usually only 4 pins are physically present (Pins 1, 7, 8, and 14). * **F:** Often represents the frequency stability or temperature range (check datasheet for specific PPM). * **C:** Typically indicates the symmetry/duty cycle (e.g., 40/60%). * **G:** Usually refers to the operating temperature range (e.g., 0°C to +70°C). * **-R:** Confirms the part is **RoHS Compliant**. --- ### 3. Pinout Configuration Even though it is called a "14-pin" package, it typically utilizes a 4-pin active layout to save space while fitting standard 14-pin sockets: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | No connection or Output Enable/Disable | | **Pin 7** | GND | Circuit Ground | | **Pin 8** | Output | The generated Square Wave frequency | | **Pin 14** | $V_{cc}$ | Positive Power Supply (+5V) | --- ### 4. Key Applications * **Legacy Computing:** Used in older motherboard designs or industrial controllers. * **Digital Signal Processing:** Providing the "heartbeat" for microprocessors. * **Networking Gear:** Timing for data transmission in routers and switches. * **Test & Measurement:** Providing stable references for frequency counters.
