The **MHO+64TAD-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is designed for applications requiring high stability and reliability in a compact through-hole package. --- ### ## Technical Specifications The following table outlines the primary electrical and physical characteristics of the MHO+64TAD-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | HCMOS / TTL Compatible | | **Frequency Range** | Typically 1.000 MHz to 100.000 MHz | | **Supply Voltage (Vcc)** | +5.0 VDC (±10%) | | **Package Style** | 14-pin DIP (Full Size), 4 Pins Connected | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±100 ppm (standard for 'A' suffix) | | **Symmetry/Duty Cycle** | 40/60% to 45/55% | | **RoHS Status** | RoHS Compliant (-R suffix) | --- ### ### Key Features and Internal Parts 1. **AT-Cut Quartz Crystal:** The heart of the unit is a precision-ground quartz crystal that determines the fundamental resonant frequency. 2. **CMOS Integrated Circuit (IC):** Contains the oscillation circuit and the output buffer. This ensures the signal is strong enough to drive multiple loads (up to 15pF or 10 TTL gates). 3. **Tristate Functionality (T):** The "T" in the part number indicates **Tri-state/Enable-Disable** capability. When Pin 1 is pulled low, the output goes into a high-impedance state, allowing for power saving or bus sharing. 4. **Hermetic Seal:** The internal components are housed in a metal "DIP" package, vacuum-sealed or filled with nitrogen to prevent aging caused by oxidation and moisture. --- ### ### Pin Configuration The MHO+64TAD-R follows the standard 14-pin DIP footprint, though only 4 pins are electrically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D (Enable/Disable) | High or Floating = Output Active; Low = High Impedance | | **7** | GND | Case and Circuit Ground | | **8** | Output | The generated frequency signal | | **14** | Vcc | +5.0V Power Supply Input | --- ### ### Part Number Breakdown * **MHO:** MtronPTI High Output series (Full size DIP). * **+:** Denotes RoHS compliance (often used interchangeably with the -R suffix). * **6:** Denotes the stability/temperature code. * **4:** Denotes the voltage (5.0V). * **T:** Denotes Tri-state function on Pin 1. * **A:** Denotes the frequency stability (e.g., ±100ppm). * **D:** Denotes the duty cycle (e.g., 40/60%). * **-R:** RoHS Compliant.
