The **ASEMDLP-L-R-T3** is a high-performance, low-profile crystal oscillator manufactured by Abracon. It belongs to the **ASEM** series, which utilizes MEMS (Micro-Electro-Mechanical Systems) technology to provide superior reliability and durability compared to traditional quartz oscillators. --- ### 1. Part Number Breakdown Understanding the specific suffix codes helps identify the exact technical specifications: | Part Segment | Meaning | Specification | | :--- | :--- | :--- | | **ASEMDLP** | Series Name | Low Power MEMS Oscillator (3.2 x 2.5 mm) | | **L** | Output Logic | LVDS (Low-Voltage Differential Signaling) | | **R** | Frequency Stability | ±25 ppm (Standard stability) | | **T3** | Packaging | Tape & Reel (3,000 units per reel) | --- ### 2. Key Technical Specifications The device is designed for high-speed data applications where jitter and power consumption are critical factors. * **Frequency Range:** Typically available from 10 MHz to 150 MHz (exact frequency is specified separately). * **Supply Voltage ($V_{dd}$):** Supports a range from +2.25V to +3.6V. * **Operating Temperature:** Typically -40°C to +85°C (Industrial Grade). * **Output Type:** **LVDS**. This provides high-speed data transmission with low electromagnetic interference (EMI). * **Package Size:** 3.2 x 2.5 x 0.85 mm (Small Form Factor). --- ### 3. Core Advantages of MEMS Technology Unlike traditional quartz crystals, the ASEMDLP series uses a silicon resonator: 1. **High Reliability:** 20x higher MTBF (Mean Time Between Failures) than quartz. 2. **Shock/Vibration Resistance:** Highly resistant to physical impact and high-vibration environments. 3. **No Activity Dips:** Consistent performance across the entire temperature range without the "frequency jumps" sometimes seen in quartz. 4. **Low Profile:** The 0.85mm height makes it ideal for height-constrained PCBs. --- ### 4. Typical Applications Because this part uses **LVDS** logic, it is primarily found in high-bandwidth communication equipment: * **Networking:** Gigabit Ethernet, Switches, and Routers. * **Storage:** Fiber Channels and SATA/SAS interfaces. * **Computing:** PCI Express and FPGA clocking. * **Industrial:** High-precision automation sensors. ---
