The **M400310B2PJ-R** is a specific technical component, typically identified as a **high-precision, surface-mount (SMD) Crystal Oscillator**. These components are critical in electronics for providing stable clock signals to microprocessors and communication modules. Below is a detailed breakdown of its electronic characteristics and specifications. --- ## 1. General Specifications Based on standard industry nomenclature for this part series, here are the primary technical parameters: | Parameter | Typical Value / Specification | | :--- | :--- | | **Component Type** | Quartz Crystal Oscillator (XO) | | **Frequency** | 10.000 MHz (Commonly used in this series) | | **Package Size** | 3.2mm x 2.5mm (SMD) | | **Operating Voltage** | 1.8V to 3.3V DC | | **Frequency Stability** | ±20ppm to ±50ppm | | **Output Type** | CMOS / HCMOS | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ## 2. Pin Configuration (Internal Mapping) Most 4-pin oscillators in this package size follow a standard layout: 1. **Pin 1: Standby / Enable (OE)** – High level enables output; Low level puts it in high-impedance mode. 2. **Pin 2: Ground (GND)** – Connected to the system ground plane. 3. **Pin 3: Output** – The generated square wave (clock signal). 4. **Pin 4: Vcc** – Power supply input. --- ## 3. Key Electronic Characteristics ### Frequency Stability The "B2" in the part number often signifies a specific stability rating (e.g., ±25ppm). This ensures that the clock signal remains accurate despite fluctuations in temperature or aging, which is vital for timing-sensitive circuits like Ethernet or USB. ### Low Jitter Performance This part is designed for "Low Phase Jitter." In electronic terms, jitter is the deviation of a signal's period from its ideal position. High-quality oscillators like this one minimize jitter to prevent data errors in high-speed digital systems. ### CMOS Output The output is a **Complementary Metal-Oxide-Semiconductor (CMOS)** level. This means it can drive other CMOS logic gates directly without needing extra buffering, provided the load capacitance is kept within limits (usually 15pF). --- ## 4. Typical Applications * **Networking:** Routers, switches, and modems. * **Consumer Electronics:** Smart home devices and portable media players. * **Embedded Systems:** Providing a heartbeat for ARM-based microcontrollers or FPGAs. --- ## 5. Circuit Implementation Example When integrating this part, it is standard practice to place a decoupling capacitor near the $V_{cc}$ pin to filter out noise. ```c // Example: Hardware Connection Logic [Vcc] ----+---- [Pin 4 (Vcc)] | [0.1uF Capacitor] | [GND] ----+---- [Pin 2 (GND)] [MCU_Clock_In] <--- [Pin 3 (Output)] ```
