The **M5R88THJ-R** is a specific electronic component, typically categorized as a high-performance **Crystal Oscillator** or a specialized **Clock Generator** module. These components are critical for providing stable timing signals in digital circuits. --- ### 1. General Specifications While specific datasheets can vary by manufacturer (often associated with brands like *Microchip* or *Vectron*), components in this series generally follow these parameters: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (SPXO / TCXO) | | **Output Frequency** | Usually fixed (e.g., 88.000 MHz or application-specific) | | **Package Type** | Surface Mount Device (SMD) | | **Operating Voltage** | Typically 3.3V or 5.0V | | **Output Logic** | CMOS / TTL Compatible | | **Frequency Stability** | ±25ppm to ±100ppm (standard range) | --- ### 2. Key Electronic Features * **Frequency Control:** The "88" in the part number often refers to the fundamental frequency (88 MHz), though this depends on the manufacturer's naming convention. * **Precision Timing:** It uses a quartz crystal resonator to create a stable square wave. This wave acts as the "heartbeat" for microprocessors and FPGAs. * **Low Phase Jitter:** High-quality oscillators like the M5R series are designed to have minimal timing variations (jitter), which is essential for high-speed data transmission. * **Tri-state Functionality:** Many versions of this part include an "Enable/Disable" pin (Pin 1), allowing the output to be turned off to save power without powering down the entire system. --- ### 3. Pin Configuration (Standard 4-Pin SMD) In a typical SMD oscillator package like the M5R series, the pins are defined as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | OE or NC | Output Enable (High = Active) or No Connection | | **2** | GND | Ground / Case Ground | | **3** | Output | The generated clock signal | | **4** | Vcc | Supply Voltage (Power Input) | --- ### 4. Common Applications These parts are found in industrial and consumer electronics where synchronization is required: * **Networking Gear:** Routers, switches, and modems. * **Computing:** Motherboards and peripheral controllers. * **Embedded Systems:** Microcontroller clock sources. * **Measuring Instruments:** Digital oscilloscopes and signal analyzers. ---
