## Overview of MHO361FCD-R The **MHO361FCD-R** is a high-performance **Clock Oscillator** (often categorized under Crystal Oscillators or XOs). These components are essential in digital electronics for providing a stable timing signal (clock pulse) that synchronizes the operations of integrated circuits like CPUs, FPGAs, and DSPs. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for the MHO series, here are the typical technical parameters: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Clock Oscillator (XO) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | Typically 5.0V (Standard for MHO series) | | **Frequency Range** | Usually 1.0 MHz to 100.0 MHz (Specific to exact model) | | **Frequency Stability** | ±25ppm to ±100ppm | | **Operating Temperature** | 0°C to +70°C (Commercial Grade) | | **Package Style** | 14-pin DIP (Full Size) or 8-pin DIP (Half Size) | --- ### 2. Electronic Composition & Functionality The MHO361FCD-R is not just a crystal; it is an **active circuit** encapsulated in a metal housing. It consists of three primary internal parts: 1. **Quartz Crystal Resonator:** The core element that vibrates at a specific frequency when an electric field is applied (Piezoelectric effect). 2. **Oscillator IC:** An internal integrated circuit that maintains the oscillation and buffers the output signal to ensure it can drive other components. 3. **Bypass Capacitor:** Internal filtering to reduce power supply noise, ensuring signal purity. --- ### 3. Pinout Configuration (Standard 14-pin DIP) Even though it uses a 14-pin footprint, only 4 pins are usually functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | NC / ED | No Connection or Output Enable/Disable | | **7** | GND | Ground connection | | **8** | Output | The generated clock signal (Square Wave) | | **14** | Vcc | Positive Power Supply (+5V) | --- ### 4. Common Applications * **Microprocessor Clocks:** Providing the heartbeat for legacy and industrial computing systems. * **Networking Equipment:** Synchronizing data transmission in routers and switches. * **Industrial Control:** Used in PLCs (Programmable Logic Controllers) where a robust through-hole component is preferred over surface-mount (SMD) for durability. * **Test & Measurement:** Providing stable time-bases for oscilloscopes and frequency counters. --- ### 5. Part Number Breakdown (Typical) * **MHO:** Series identifier (usually indicates a metal-can DIP package). * **3:** Represents the voltage or stability class (often 5V). * **61:** Specific frequency/designators. * **FCD:** Features (e.g., Fixed frequency, CMOS output, Duty cycle). * **R:** RoHS compliant (Lead-free).
