## M7S15FBJ-R Electronic Component Overview The **M7S15FBJ-R** is a high-precision, surface-mount Crystal Oscillator manufactured by **MtronPTI**. It belongs to the M7S series, which is known for providing reliable clock signals in a compact 5x7mm package. --- ### 1. Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Component Type** | XO (Standard Crystal Oscillator) | | **Frequency Range** | Usually fixed (e.g., 1.0 MHz to 125 MHz, check specific variant) | | **Output Type** | HCMOS / TTL Compatible | | **Operating Voltage** | 5.0V (Standard for the M7S series) | | **Package Size** | 5.0 x 7.0 mm (4-Pad SMD) | | **Frequency Stability** | ±100 ppm (Standard), options for ±25 or ±50 ppm | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **RoHS Status** | Compliant (R-suffix indicates RoHS) | --- ### 2. Functional Description The M7S15FBJ-R acts as the "heartbeat" of an electronic circuit. It combines a quartz crystal blank with an oscillation circuit and an output buffer into a single hermetically sealed package. * **HCMOS/TTL Output:** It provides a square wave signal capable of driving high-speed CMOS or older TTL logic gates. * **Tri-state Function (J-Type):** The "J" in the part number often indicates a **Tri-state (Output Enable)** function on Pin 1. This allows the oscillator to remain powered while the output is electronically disconnected, reducing EMI and power consumption when the clock is not needed. * **High Reliability:** Designed for harsh environments, making it suitable for industrial automation and communications. --- ### 3. Pin Configuration (Typical 4-Pad) | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Output Enable/Disable (Tri-state) | | **2** | GND | Circuit Ground | | **3** | Output | Frequency Signal Output | | **4** | Vdd | Supply Voltage (+5.0V) | --- ### 4. Common Applications * **Networking:** Routers, switches, and modems. * **Industrial:** Programmable Logic Controllers (PLCs) and embedded systems. * **Computing:** Clock generators for microprocessors and peripherals. * **Storage:** Fiber channel and disk drive controllers. ---
