The **MHO+33FBG-R** is a high-precision, high-frequency crystal oscillator (OCXO/TCXO derivative) typically manufactured by companies like **MtronPTI**. This specific part number follows a modular naming convention used in timing and frequency control components. ### 1. General Specifications The part belongs to the **MHO+ series**, which focuses on high-stability clock generation for telecommunications and industrial equipment. | Parameter | Description | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Style** | 14-pin DIP (Dual In-line Package) - Full size | | **Output Type** | HCMOS/TTL Compatible | | **Operating Voltage** | Typically 3.3V or 5.0V (Check specific datasheet suffix) | | **Frequency Range** | Usually 1.0 MHz to 160.0 MHz | --- ### 2. Part Number Breakdown While manufacturer codes vary slightly, the "MHO+33FBG-R" generally breaks down as follows: * **MHO+**: Product Series (Metal Thru-Hole, High Stability). * **3**: Operating Voltage (often indicates 3.3V). * **3**: Stability Grade (often indicates ±25ppm or ±50ppm depending on the temperature table). * **F**: Temperature Range (Standard Industrial: -40°C to +85°C). * **B**: Duty Cycle (typically 40/60% or 45/55%). * **G**: Frequency Stability code. * **-R**: RoHS Compliant (Lead-free). --- ### 3. Key Electronic Characteristics These oscillators are preferred over standard ceramic resonators due to their superior stability. 1. **Low Jitter:** Designed for high-speed data transmission to minimize timing errors. 2. **Tri-state Function:** Usually includes an Enable/Disable pin (Pin 1), allowing the output to go into a high-impedance state for testing or power saving. 3. **Hermetic Sealing:** The metal "can" (DIP-14) is resistance-welded to protect the quartz crystal from humidity and atmospheric interference. ### 4. Typical Pin Configuration For a standard 14-pin DIP package: | Pin Number | Function | | :--- | :--- | | **1** | NC (No Connection) or Tri-state Enable | | **7** | Case Ground (GND) | | **8** | Output Signal | | **14** | Supply Voltage (Vcc) | --- ### 5. Common Applications * **Networking:** Synchronous Ethernet, routers, and switches. * **Telecommunications:** Base stations and transmission hardware. * **Industrial:** System clocks for PLC (Programmable Logic Controllers). * **Test Equipment:** Frequency counters and signal generators.
