The **M5R25ZPJ-R** is a high-precision, industrial-grade crystal oscillator belonging to the **M5R series** manufactured by **MtronPTI**. It is designed for high-reliability applications requiring high frequencies and tight stability. --- ### 1. Technical Specifications The following table highlights the core electronic characteristics of the M5R25ZPJ-R: | Feature | Specification | | :--- | :--- | | **Component Type** | XO (Clock Oscillator) | | **Frequency Range** | Typically 1 MHz to 150 MHz (Specific to model) | | **Output Type** | CMOS / TTL Compatible | | **Supply Voltage (Vcc)** | +5.0V DC (±10%) | | **Frequency Stability** | ±25 ppm (Standard for 'Z' variant) | | **Operating Temp Range** | -40°C to +85°C (Industrial Grade) | | **Package Style** | J-Lead (Surface Mount) | | **Packaging** | Tape & Reel (indicated by the '-R' suffix) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific electronic capabilities: * **M5**: Indicates the series (5.0V operation). * **R**: Refers to the Symmetry/Duty Cycle (typically 40/60% or 45/55%). * **25**: Frequency Stability. This signifies **±25 parts per million (ppm)**. * **Z**: Operating Temperature. This code represents the **-40°C to +85°C** range. * **PJ**: Package type, specifically the **J-lead plastic molded** surface mount package. * **-R**: Indicates **Tape and Reel** packaging for automated assembly. --- ### 3. Key Electronic Features * **Tri-state Functionality:** Pin 1 usually serves as a "Tristate" (Enable/Disable) pin. When low, the output goes into a high-impedance state, allowing for power saving and easier testing. * **HCMOS/TTL Compatibility:** It can drive both High-speed CMOS and older TTL logic loads, making it versatile for legacy and modern circuit designs. * **Low Phase Jitter:** Designed for timing-sensitive applications like networking and data communications. * **Environmental Resilience:** The J-lead package provides excellent solder joint integrity and thermal expansion compliance, suitable for harsh environments. --- ### 4. Common Applications Due to its 5V operation and industrial temperature rating, it is commonly used in: 1. **Industrial Controllers:** PLC systems and factory automation. 2. **Telecommunications:** Base stations and switching hardware. 3. **Embedded Systems:** Microprocessor clocking where 5V logic is still prevalent. 4. **Test & Measurement:** Oscilloscopes and signal generators. ---
