Based on the part number provided, the **M5R18RP-R** refers to a high-performance **Oscillator**, specifically a part of the M5R series by MtronPTI. These components are essential in electronics for providing a stable clock signal. --- ## Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Output Type** | LVPECL (Low-Voltage Positive Emitter-Coupled Logic) | | **Package Type** | 5x7 mm Surface Mount (SMD) | | **Voltage Supply** | Typically 3.3V (Standard for R-series) | | **Pin Count** | 6-Pad Ceramic Leadless Chip Carrier | | **RoHS Status** | Compliant (Indicated by -R suffix) | --- ## Key Features ### 1. LVPECL Output The "R" in the designation often signifies **LVPECL** logic. This is preferred in high-speed data applications because it offers: * Fast transition times (rise/fall). * Low jitter (minimal timing uncertainty). * Differential signaling to reduce electromagnetic interference (EMI). ### 2. Physical Design The part is housed in a **5x7mm ceramic package**. This industry-standard size allows for high durability and excellent thermal stability. The hermetic seal protects the internal quartz crystal from moisture and environmental contaminants. ### 3. Stability and Precision These parts are engineered for telecommunications and networking, offering frequency stabilities often in the range of ±20ppm to ±100ppm depending on the specific frequency configuration. --- ## Common Applications * **Networking:** Gigabit Ethernet, Fibre Channel, and SONET/SDH. * **Computing:** High-speed servers and data storage arrays. * **Telecommunications:** Base stations and optical line terminals. * **Test Equipment:** Oscilloscopes and frequency counters requiring a stable reference. --- ## Pin Configuration (Standard 6-Pad) | Pin # | Function | Description | | :--- | :--- | :--- | | 1 | E/D or NC | Enable/Disable (Tristate) or No Connect | | 2 | NC | No Connect | | 3 | GND | Case Ground | | 4 | Output | Main Clock Signal | | 5 | Complementary Output | Inverted Clock Signal (Differential) | | 6 | Vcc | Supply Voltage |
