The **MHO+64TFG-R** is a specific series of high-precision crystal oscillators, typically manufactured by **MtronPTI**. These components are widely used in telecommunications, networking, and industrial equipment where stable timing signals are required. --- ## Technical Specifications The part number follows a specific nomenclature that defines its electronic characteristics. | Parameter | Specification Details | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Package Type** | 14-pin DIP (Dual In-line Package) - Full Size | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage** | 5.0V (Standard for the MHO series) | | **Frequency Stability** | Generally ±100ppm to ±25ppm (depending on suffix) | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (Indicated by the "R" suffix) | --- ## Breakdown of the Part Number Understanding each segment of the code helps in identifying the exact electronic behavior: ### 1. **MHO** This identifies the product series. The MHO series consists of high-speed CMOS/TTL compatible oscillators housed in a metal, hermetically sealed package to reduce Electromagnetic Interference (EMI). ### 2. **6** (Voltage Code) This digit usually represents the operating voltage. In the MtronPTI system, "6" typically denotes a **5.0V DC** power supply. ### 4. **4** (Stability/Temperature) This digit refers to the frequency stability over a specific temperature range. For this series, a "4" often indicates a stability of **±50ppm** over the industrial temperature range. ### 5. **TFG** (Feature Set) * **T**: Tri-state Enable/Disable function (allows the output to be disconnected electronically). * **F**: Full-size DIP package (as opposed to half-size). * **G**: Specific internal circuit tuning or "Gull-wing" lead configuration (though usually, in DIP parts, this refers to internal grounding/grading). ### 6. **R** (Compliance) The **R** stands for **RoHS Compliant**, meaning the part is manufactured without lead (Pb) or other hazardous substances. --- ## Internal Connections (Pinout) For a standard 14-pin Full-size DIP Oscillator like the MHO+64TFG-R, the pins are arranged as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **Pin 1** | N/C or Tri-state | Leave open or pull high for output; pull low to disable. | | **Pin 7** | Ground | Case Ground / Negative Supply. | | **Pin 8** | Output | The generated clock signal (Square Wave). | | **Pin 14** | Vcc | +5.0V DC Power Supply. | --- ## Common Applications * **Networking**: Used in Ethernet switches and routers for synchronous data transmission. * **Legacy Hardware**: Common in industrial motherboards and embedded systems that require 5V logic. * **Test Equipment**: Signal generators and frequency counters.
