The **MEH52ZBD-R** is a specific electronic component, primarily recognized as a **high-precision, surface-mount (SMD) crystal oscillator**. These components are critical for providing a stable clock signal to microprocessors and digital circuits. --- ### 1. Technical Specifications The following table outlines the typical electrical and mechanical characteristics of the MEH series: | Parameter | Specification | | :--- | :--- | | **Component Type** | XO (Crystal Oscillator) | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 4-Pad (Standard footprint, often 5x7mm or 3.2x5mm) | | **Output Type** | CMOS / TTL | | **Voltage Supply** | Typically 3.3V or 5.0V | | **Operating Temp** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±25ppm to ±100ppm (depending on suffix) | --- ### 2. Functional Breakdown To understand how this part functions within a circuit, we can look at its internal blocks: * **Piezoelectric Quartz Crystal:** The "heart" of the component. It vibrates at a specific frequency when voltage is applied. * **Oscillator IC:** An internal integrated circuit that amplifies the crystal's vibration and converts it into a clean square wave (digital pulse). * **Tri-state Function (Enable/Disable):** Most "BD" variants include a pin that allows the system to turn the clock signal on or off to save power. --- ### 3. Pin Configuration Standard 4-pin layout for this series: ```text Pin 1: Enable/Disable (Standby) Pin 2: Ground (VSS) Pin 3: Output (Frequency Signal) Pin 4: Supply Voltage (VDD) ``` --- ### 4. Typical Applications The MEH52ZBD-R is commonly found in electronics requiring timing precision: 1. **Networking Hardware:** Switches, routers, and modems. 2. **Embedded Systems:** Microcontrollers (MCU) and FPGAs. 3. **Consumer Electronics:** High-definition video equipment and audio interfaces. 4. **Automotive:** Control units where temperature stability is necessary. ---
