Based on the part number **M7S33FAJ-R**, this component is a high-performance **Programmable Crystal Oscillator** manufactured by **NDK (Nihon Dempa Kogyo)**. It belongs to the M7S series, which is known for its versatility in frequency configuration and low power consumption. --- ### ## Technical Specifications The following table outlines the primary electronic characteristics of the M7S33FAJ-R: | Parameter | Specification | Details | | :--- | :--- | :--- | | **Output Frequency** | 1.0 to 125 MHz | Programmable (Factory set) | | **Supply Voltage (Vcc)** | +3.3V | Range: 3.0V to 3.6V | | **Output Type** | CMOS | Rail-to-rail digital signal | | **Package Size** | 7.0 x 5.0 mm | Standard 4-pad SMD package | | **Operating Temp** | -40 to +85 °C | Industrial grade | | **Frequency Stability** | ±50 ppm | Total stability including temp/aging | | **Standby Current** | < 10 µA | Power-saving mode enabled | --- ### ### Core Features * **Programmability:** Unlike fixed-frequency crystals, the M7S series uses a PLL (Phase-Locked Loop) internal architecture, allowing for any specific frequency to be programmed within its range. * **Standby Function:** It includes a Standby/Enable pin (usually Pin 1). When pulled low, the oscillator stops, and current consumption drops significantly to extend battery life. * **SMD Packaging:** The ceramic package is designed for high-density surface mount technology (SMT) with standard 7050 footprints. ### ### Typical Pin Configuration ```text Pin 1: Standby (ST) or No Connect (NC) Pin 2: Ground (GND) Pin 3: Output (OUT) Pin 4: Supply Voltage (Vcc) ``` ### ### Applications 1. **Industrial Equipment:** Reliable timing for PLCs and industrial controllers. 2. **Networking:** Clocking for Ethernet switches and routers. 3. **Consumer Electronics:** High-speed data processing in cameras and displays. 4. **Prototyping:** Ideal for designs where frequency requirements might change during development. ---
