The **MHO+61TAD-R** is a specific series of **Crystal Oscillators** (specifically Temperature Compensated Crystal Oscillators or standard Clock Oscillators, depending on the manufacturer’s specific prefix variant) typically manufactured by companies like **MtronPTI**. Below is a detailed breakdown of the electronic specifications and characteristics of this component. --- ### 1. General Specifications The part number follows a specific nomenclature that defines its electrical behavior. | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Full Size) | | **Output Type** | CMOS / TTL Compatible | | **Input Voltage ($V_{cc}$)** | Typically 5.0V DC | | **Frequency Range** | Usually 1.000 MHz to 100.000 MHz (Specific to order) | | **RoHS Status** | Compliant (Indicated by the "-R" suffix) | --- ### 2. Pin Configuration Since this is a standard 14-pin DIP package (often with only 4 pins actually present), the pinout is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock signal (Square Wave) | | **14** | $V_{cc}$ | Positive Power Supply (+5V) | --- ### 3. Key Electronic Characteristics #### A. Signal Integrity The "T" in the part number often signifies **TTL compatibility**, meaning the logic high and low levels are calibrated to work with older TTL logic families as well as modern CMOS circuits. It provides a clean square wave signal with specific rise and fall times (usually $<10ns$). #### B. Frequency Stability The "A" or "D" codes in the middle of the part number usually represent the **Frequency Stability** and **Operating Temperature Range**. * **Stability:** Often $\pm 100$ ppm, $\pm 50$ ppm, or $\pm 25$ ppm. * **Temperature:** Standard commercial ($0^\circ C$ to $+70^\circ C$) or Industrial ($-40^\circ C$ to $+85^\circ C$). #### C. The "-R" Suffix This is a critical identifier in modern electronics: * **RoHS Compliant:** It confirms the part is lead-free and meets environmental safety standards. * **Standardization:** It ensures compatibility with modern lead-free soldering processes. --- ### 4. Applications The MHO+61TAD-R is commonly used in legacy and industrial hardware where a reliable, through-hole timing source is required: * **Microprocessor Clocks:** Providing the "heartbeat" for CPUs. * **Networking Equipment:** Timing for data transmission in routers or switches. * **Industrial Controllers:** Used in PLCs (Programmable Logic Controllers). * **Embedded Systems:** For timing in medical or testing equipment. ---
