Based on the part number provided, the **M5R88ZLJ-R** refers to a specific type of **Crystal Oscillator** or **Frequency Control Device**, typically manufactured by companies like **Mercury Electronic**. These components are essential for providing a stable clock signal in electronic circuits. --- ### 1. Component Overview The M5R series generally represents a High-Frequency, Surface Mount (SMD) Crystal Oscillator. These parts are designed for high precision and low jitter. | Attribute | Typical Specification | | :--- | :--- | | **Part Type** | Crystal Clock Oscillator (XO) | | **Package Type** | SMD (Surface Mount Device) | | **Common Frequency Range** | 1 MHz to 150 MHz (Specific to exact sub-model) | | **Supply Voltage** | Usually 3.3V or 5.0V | | **Output Logic** | HCMOS / TTL Compatible | | **RoHS Status** | Compliant (indicated by -R suffix) | --- ### 2. Breakdown of the Part Number While naming conventions vary slightly by manufacturer, the code generally breaks down as follows: * **M5R:** The Series designation (often indicating a 5.0x7.0 mm package size). * **88:** Often refers to the stability or temperature range (e.g., ±25ppm or ±50ppm). * **ZLJ:** Internal manufacturer codes for specific output characteristics or custom frequency trims. * **-R:** Indicates "RoHS Compliant" or "Tape and Reel" packaging. --- ### 3. Key Electronic Characteristics These parts are defined by several critical electrical parameters: 1. **Frequency Stability:** Measured in parts per million (PPM). This determines how much the frequency drifts over time and temperature. 2. **Jitter:** The deviation from true periodicity of a signal. Low jitter is crucial for high-speed data communication. 3. **Duty Cycle:** Typically 40/60% or 45/55%, representing the symmetry of the square wave output. 4. **Enable/Disable Function:** Most M5R oscillators include a "Tri-state" function on Pin 1, allowing the output to be turned off to save power. --- ### 4. Typical Application Circuit In most designs, the oscillator is connected as follows: ```c [VCC] ----+---- (Pin 4: VDD) | [0.1uF Bypass Cap] | [GND] ----+---- (Pin 2: GND) (Pin 1: OE) --- [Logic High to Enable] (Pin 3: OUT) --- [Clock Input of Microcontroller/FPGA] ``` ---
