The **ASEMDLP-L-R-T** is a specific part number for a high-performance, low-jitter crystal oscillator manufactured by **Abracon**. This component belongs to the **ASEM** series, which utilizes MEMS (Micro-Electro-Mechanical Systems) technology rather than traditional quartz. --- ### 1. Part Number Breakdown Understanding the suffix codes is essential for identifying the specific electrical characteristics of this component: | Code Segment | Meaning | Description | | :--- | :--- | :--- | | **ASEMDLP** | Series & Output | Low Power MEMS Oscillator with **LVDS** Output | | **-L** | Frequency Stability | Typically denotes $\pm 50$ ppm (parts per million) | | **-R** | Temperature Range | Industrial grade: $-40^{\circ}\text{C}$ to $+85^{\circ}\text{C}$ | | **-T** | Packaging | Tape & Reel (usually 1,000 or 3,000 pieces) | --- ### 2. Technical Specifications The "LP" in the part name indicates it is optimized for **Low Power** and uses **LVDS** (Low Voltage Differential Signaling), which is ideal for high-speed data transfer with low EMI (Electromagnetic Interference). * **Frequency Range:** Available from 2.3 MHz to 460 MHz (factory programmed). * **Supply Voltage:** Typically 2.25V to 3.6V. * **Package Size:** 3.2 x 2.5 x 0.85 mm (SMD footprint). * **Output Type:** Differential LVDS. * **Technology:** PureSilicon™ MEMS (resilient to shock and vibration). --- ### 3. Key Features & Benefits 1. **High Reliability:** Because it uses MEMS technology instead of a physical quartz crystal, it is 20 times more resistant to mechanical shock and vibration. 2. **Low Jitter:** Designed for clocking high-speed serial protocols where timing precision is critical. 3. **No Activity Dips:** Unlike quartz, MEMS oscillators do not suffer from "activity dips" or "micro-jumps" across the temperature range. 4. **Compact Form Factor:** The 3.2 x 2.5 mm package is an industry standard, allowing for easy PCB integration. --- ### 4. Common Applications This part is commonly found in communication and high-speed computing environments: * **Networking:** 10/100/1000 Ethernet, switches, and routers. * **Storage:** Fiber Channel, SATA, and SAS interfaces. * **Computing:** PCI-Express clocks and FPGA reference clocks. * **Industrial:** High-vibration environments where quartz might fail. --- ### 5. Pin Configuration (3.2 x 2.5mm Package) ```markdown Pin 1: Enable/Disable (High = Output / Low = Tri-state) Pin 2: No Connect (NC) Pin 3: Ground (GND) Pin 4: Output (Standard) Pin 5: Complementary Output (Inverse) Pin 6: Supply Voltage (VDD) ```
