The **MHO+23TCG-R** is a high-precision, industrial-grade **Crystal Oscillator** (Clock Oscillator). It is designed to provide a stable frequency reference for electronic circuits, specifically categorized under the MHO series by manufacturers like MtronPTI. --- ## 1. Technical Specifications The part number follows a specific nomenclature. Here are the typical technical parameters for this component: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Frequency Range** | Typically fixed (often in the MHz range) | | **Supply Voltage** | 3.3V or 5.0V (Standard for TCG series) | | **Output Type** | CMOS / TTL Compatible | | **Package Style** | 14-pin DIP (Thru-hole) - Full Size | | **Stability** | ±100ppm to ±25ppm (depending on suffix) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by "-R") | --- ## 2. Pin Configuration Since this is a standard 14-pin DIP package (often with only 4 physical pins present), the layout is as follows: 1. **Pin 1: N/C or Tri-state Control** (Allows the output to be disabled/enabled). 2. **Pin 7: Ground (GND)**. 3. **Pin 8: Output** (The clock signal). 4. **Pin 14: Vcc** (Positive Power Supply). --- ## 3. Key Features * **Hermetically Sealed:** The metal "can" package protects the quartz crystal from humidity and atmospheric contaminants, ensuring long-term frequency stability. * **Integrated Design:** Unlike a simple crystal, this "oscillator" includes the quartz blank plus the internal load capacitors and the transistor/IC required to make it vibrate. No external circuitry is needed besides power. * **Low Jitter:** Designed for timing-critical applications where signal "drift" must be minimized. --- ## 4. Common Applications * **Embedded Systems:** Providing the master clock for Microcontrollers (MCUs) or FPGAs. * **Networking:** Synchronizing data transmission in routers and switches. * **Industrial Controls:** Used in PLC (Programmable Logic Controllers) where temperature fluctuations are common. * **Legacy Hardware:** The 14-pin DIP format is frequently used in older hardware repairs or robust industrial equipment. ---
