The **MHO+72TCG-R** is a high-performance **Crystal Oscillator (XO)** manufactured by MtronPTI. It is specifically designed as a CMOS/TTL compatible clock source used in high-reliability industrial and communication hardware. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of the MHO+72TCG-R: | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (Fixed Frequency) | | **Output Type** | HCMOS / TTL Compatible | | **Frequency Range** | Typically customized (Commonly 1.0 MHz to 100.0 MHz) | | **Supply Voltage (Vcc)** | +5.0V DC (±10%) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full Size | | **Frequency Stability** | ±100 ppm (Standard for 'T' Grade) | | **Operating Temp Range** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (indicated by the 'R' suffix) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific features of this electronic part: * **MHO:** Series prefix for MtronPTI High-Speed CMOS/TTL Oscillators. * **+:** Indicates a 5.0V operating voltage. * **7:** Refers to the "Full Size" 14-pin DIP metal package. * **2:** Designates the Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **T:** Represents the Operating Temperature range (-40°C to +85°C). * **C:** Represents the Frequency Stability (±100 ppm). * **G:** Indicates the Tri-state Enable/Disable function on Pin 1. * **-R:** RoHS Compliant (Lead-Free). --- ### 3. Pin Configuration In a standard 14-pin DIP oscillator like this, only four pins are typically active: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D (Enable/Disable) | Logic "1" or Open = Output Active; Logic "0" = High Impedance. | | **7** | Case Ground | Connected to the metal housing to reduce EMI. | | **8** | Output | The generated clock signal. | | **14** | Vcc | +5.0V Power Supply input. | --- ### 4. Applications The MHO+72TCG-R is commonly utilized in legacy and high-reliability systems where surface-mount (SMD) components are not desired, or for prototyping on breadboards/perf-boards: * **Networking Gear:** Hubs, routers, and switches. * **Industrial Controllers:** PLC units and automation timing. * **Test Equipment:** Signal generators and measurement devices. * **Embedded Systems:** Microprocessor and Microcontroller clocking.
