The **M2AS1-4133-R** is a specific electronic component, typically categorized as a high-performance **Crystal Oscillator**. It is commonly utilized in telecommunications, networking, and high-speed data processing equipment where precise timing is critical. --- ### 1. General Specifications Below is a breakdown of the typical technical parameters associated with this part number: | Parameter | Specification | | :--- | :--- | | **Part Type** | Crystal Oscillator (XO) | | **Nominal Frequency** | Often associated with 133.33 MHz or custom variants | | **Output Type** | LVPECL or LVDS (Differential Signals) | | **Supply Voltage** | 3.3V (Typical) | | **Package Size** | 5x7mm or 3.2x5mm SMD (Surface Mount) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Frequency Stability** | ±25ppm to ±50ppm | --- ### 2. Key Electronic Features #### Differential Signaling The "AS" designation in many oscillator series refers to the use of **LVPECL (Low-Voltage Positive Emitter-Coupled Logic)**. * **Benefit:** High noise immunity and the ability to drive long PCB traces at high frequencies. * **Application:** Ideal for clocking FPGAs, high-speed Ethernet, and PCIe interfaces. #### Low Jitter Performance This component is designed for low phase noise and low jitter. Jitter refers to the deviation from the true periodicity of a signal. For high-speed data transmission, low jitter ensures that data bits are sampled correctly at the receiving end. #### SMD Packaging The "R" suffix often denotes **Tape & Reel** packaging, indicating that the parts are prepared for automated "Pick and Place" assembly lines. --- ### 3.
