The **M8XT2-9V2V2-R** is a high-precision, low-voltage differential signaling (LVDS) clock oscillator, typically used in high-speed networking, telecommunications, and industrial automation. --- ### 1. Key Technical Specifications Below is a breakdown of the primary electronic parameters for this component: | Parameter | Specification | | :--- | :--- | | **Output Type** | LVDS (Low-Voltage Differential Signaling) | | **Nominal Frequency** | Varies by sub-model (Commonly 100MHz - 156.25MHz) | | **Supply Voltage ($V_{dd}$)** | 2.5V or 3.3V (Dual Compatibility) | | **Frequency Stability** | ±25 ppm to ±50 ppm | | **Package Size** | 7.0 x 5.0 mm (6-pad SMD) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Phase Jitter** | < 1 ps RMS (12 kHz to 20 MHz) | --- ### 2. Functional Components The device consists of three main internal electronic blocks: 1. **Crystal Resonator:** A high-Q quartz crystal that provides the base physical oscillation. 2. **Oscillator IC:** An Integrated Circuit that maintains the oscillation and handles temperature compensation to ensure stability. 3. **LVDS Output Buffer:** Converts the internal signal into a differential pair ($V_{out+}$ and $V_{out-}$) to minimize electromagnetic interference (EMI) and allow for high-speed data transmission over long traces. --- ### 3. Pin Configuration For standard 7.0 x 5.0 mm 6-pad oscillators like the M8XT2 series: | Pin # | Function | Description | | :--- | :--- | :--- | | **1** | OE (Output Enable) | Logic '1' enables output; Logic '0' disables (High Impedance) | | **2** | NC | No Connection (internally disconnected) | | **3** | GND | Ground / Case | | **4** | Output | Positive Output | | **5** | Complementary Output | Negative Output | | **6** | $V_{dd}$ | Supply Voltage | --- ### 4.
