The **MHO+52TCD-R** is a specific type of **Crystal Oscillator** (specifically a Clock Oscillator) manufactured by MtronPTI. These components are essential in digital electronics for providing a precise, stable timing signal (clock pulse) required for microprocessors and communication circuits. --- ## 1. Technical Specifications The model name is part of a coded series. Below are the typical technical parameters associated with this part number: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Package Style** | 14-pin DIP (Half-size or Full-size compatible) | | **Output Type** | HCMOS / TTL | | **Supply Voltage (Vcc)** | +5.0 VDC | | **Frequency Stability** | Usually ±50ppm or ±100ppm (depending on suffix) | | **Operating Temperature** | 0°C to +70°C (Standard Commercial) | | **RoHS Status** | Lead-Free / Compliant (indicated by -R) | --- ## 2. Pin Configuration (Internal Mapping) Although these often come in a 4-pin rectangular metal "can" package, they occupy the footprint of a 14-pin DIP socket. | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | N/C or Tri-State | No connection or Output Enable/Disable | | **7** | GND | Circuit Ground | | **8** | Output | The generated clock frequency signal | | **14** | Vcc | +5V Power Supply | --- ## 3. Key Features and Applications ### Features * **Metal Encapsulation:** The "can" is hermetically sealed to protect the quartz crystal from humidity and provide EMI shielding. * **Integrated Circuitry:** Unlike a bare crystal, this part includes the internal load capacitors and the oscillation circuit; it only requires power to function. * **Thru-Hole Mounting:** Designed for traditional PCB mounting or socket insertion. ### Applications * **Legacy Computing:** Common in older industrial PC motherboards. * **Embedded Systems:** Providing a master clock for 8-bit or 16-bit microcontrollers. * **Networking Gear:** Timing for routers, switches, and modems. * **Test Equipment:** Stable frequency reference for signal generators. --- ## 4. Part Number Breakdown * **MHO:** Series designation (HCMOS/TTL compatible). * **+:** Often indicates a specific revision or lead-free process improvement. * **52:** Code for frequency stability (typically ±50 ppm). * **T:** Denotes "Tri-state" capability (Pin 1 can turn the output on/off). * **C:** Commercial temperature range. * **D:** Dual-in-line package format. * **-R:** RoHS compliant (Lead-free).
