The **MHO+41TGG-R** is a specific part number belonging to the **MHO series** of crystal clock oscillators manufactured by **MtronPTI**. These components are critical for providing precise timing signals in digital circuits. --- ### 1. Part Number Breakdown The nomenclature for MtronPTI oscillators identifies the specific physical and electrical characteristics: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **MHO** | Series Name | 14-pin DIP (Hole-through) Crystal Oscillator | | **+** | RoHS Compliance | Lead-free / RoHS Compliant | | **4** | Operating Voltage | +5.0 VDC (Standard) | | **1** | Temperature Stability | ±100 ppm (Standard Commercial) | | **T** | Symmetry/Duty Cycle | 40/60% to 60/40% | | **GG** | Frequency Range | Typically refers to specific MHz ranges (e.g., ~1.0 MHz to 100 MHz) | | **-R** | Packaging | RoHS/Tape & Reel or specific revision indicator | --- ### 2. Key Technical Specifications While the exact frequency (in MHz) is usually appended to the end of this string (e.g., *MHO+41TGG-R 10.000MHz*), the series shares these common traits: * **Output Type:** TTL / CMOS Compatible. * **Package Style:** 14-pin DIP (Dual In-line Package). Note: Only 4 pins are usually present (Pins 1, 7, 8, 14). * **Operating Temperature:** 0°C to +70°C (Standard commercial grade). * **Input Voltage:** 5V ± 10%. * **Frequency Stability:** ±100ppm (includes calibration at 25°C, stability over temperature, and voltage/load variations). --- ### 3. Pin Configuration (14-pin DIP Layout) Although it uses a 14-pin footprint, only four pins are functional: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-state | No connection or Output Enable/Disable | | **7** | GND | Case and Circuit Ground | | **8** | Output | The Clock Signal (Square Wave) | | **14** | Vcc | Supply Voltage (+5V) | --- ### 4. Typical Applications The MHO series is legacy-style hardware often used in: * **Industrial Control Systems:** Where older through-hole PCB designs are still utilized. * **Microprocessor Clocks:** Providing the "heartbeat" for 8-bit or 16-bit CPUs. * **Networking Equipment:** For synchronization in hubs or switches. * **Test & Measurement:** General-purpose signal generation. ---
