Based on the part number **M7S43FDJ-R**, this component is a high-performance **Crystal Oscillator** (specifically a MEMS or Quartz-based Fixed Frequency Oscillator) manufactured by **TXC Corporation**. This series is designed for high-stability applications requiring small form factors and low jitter. --- ### 1. Technical Specifications The following table outlines the typical electrical and physical characteristics of the M7 series: | Parameter | Specification | | :--- | :--- | | **Product Category** | Standard Clock Oscillator | | **Package Size** | 7.0 x 5.0 mm (SMD) | | **Output Type** | LVDS / LVPECL / HCSL (Differential) | | **Supply Voltage** | 2.5V or 3.3V (Typical) | | **Frequency Stability** | ±25ppm to ±50ppm | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Mounting Type** | Surface Mount (SMT) | | **Packing Type** | Tape & Reel (indicated by the "-R" suffix) | --- ### 2. Key Features * **Differential Output:** Supports high-speed data transmission by using differential signaling (like LVPECL or LVDS), which reduces electromagnetic interference (EMI). * **Low Phase Jitter:** Optimized for clocking high-speed Serializer/Deserializer (SerDes) and ASICs. * **Tri-state Function:** Allows the output to be disabled (high-impedance state) for power saving or testing purposes. * **RoHS Compliant:** Lead-free and environmentally friendly materials. --- ### 3. Pin Configuration (Typical 6-Pad Layout) Standard 7050 size differential oscillators usually follow this pinout: ```text Pad 1: OE (Output Enable) or NC Pad 2: NC (No Connection) Pad 3: GND (Ground) Pad 4: OUT (Output) Pad 5: OUTN (Complementary Output) Pad 6: VDD (Supply Voltage) ``` --- ### 4. Applications Due to its stability and differential output, this part is commonly found in: 1. **Networking:** 10G/40G/100G Ethernet switches and routers. 2. **Fiber Channel:** Storage Area Networks (SAN). 3. **Computing:** Servers, RAID controllers, and high-performance workstations. 4. **Telecom:** Base stations and optical transmission equipment.
