Based on the part number provided, **MHO+61FDG-R** refers to a specific series of **Crystal Oscillators** manufactured by **MtronPTI**. These are high-precision timing components used in digital circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by MtronPTI to define its electrical and physical characteristics. | Parameter | Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | Typically 5.0V (indicated by the '6' or series code) | | **Operating Temp** | -40°C to +85°C (Industrial Grade, indicated by 'D') | | **Stability** | ±100 ppm or ±50 ppm (depending on specific sub-coding) | | **RoHS Status** | Lead-Free / Compliant (indicated by the 'R' suffix) | --- ### 2. Breakdown of the Part Number While internal manufacturer codes can vary slightly over time, the general breakdown for the **MHO** series is as follows: 1. **MHO**: The Series prefix for "Mtron High-Output" or standard HCMOS/TTL oscillators in a metal DIP package. 2. **6**: Represents the Voltage (usually 5.0V) and specific package height. 3. **1**: Denotes the symmetry/duty cycle (typically 40/60%). 4. **F**: Frequency Stability code (typically ±100ppm). 5. **D**: Operating Temperature Range code (-40°C to +85°C). 6. **G**: Output load or Pin 1 configuration (G usually means "No Connection" or "Tristate" on Pin 1). 7. **R**: RoHS Compliant. --- ### 3. Key Electronic Functions * **Frequency Generation:** It provides a stable clock signal required for microprocessors, DSPs, and FPGAs to execute instructions. * **HCMOS/TTL Output:** It can drive multiple logic gates directly without needing additional buffering, making it versatile for older and industrial logic circuits. * **Hermetic Sealing:** The metal "can" (DIP-14) is hermetically sealed to protect the quartz crystal from moisture and atmospheric pressure changes, ensuring long-term frequency stability. --- ### 4. Typical Applications * **Industrial Control Systems:** Used in PLC (Programmable Logic Controllers) due to the robust DIP packaging. * **Communication Equipment:** Providing timing for data transmission. * **Legacy Computing:** Replacement parts for older motherboards or embedded systems that require 5V logic. --- ### 5. Pinout Diagram (Standard 14-pin DIP) Though it has a 14-pin footprint, only 4 pins are typically active: | Pin Number | Function | | :--- | :--- | | **Pin 1** | N/C or Tristate (Enable/Disable) | | **Pin 7** | Case Ground (GND) | | **Pin 8** | Output Signal (Clock) | | **Pin 14** | Supply Voltage (Vcc) | ---
