The **DSA6331JI3JB-T** is a high-performance, ultra-small MEMS (Micro-Electro-Mechanical Systems) oscillator produced by **Microchip Technology**. It is part of the DSA6300 series, specifically designed for automotive applications and space-constrained designs. --- ### 1. Key Technical Specifications The part number encodes specific characteristics of the component. Here is the breakdown of its technical profile: | Feature | Specification | | :--- | :--- | | **Type** | MEMS Oscillator | | **Output Frequency** | 25 MHz (Standard for this sub-series) | | **Supply Voltage** | 1.71V to 3.63V | | **Stability** | ±50 ppm | | **Operating Temperature** | -40°C to +125°C (AEC-Q100 Grade 1) | | **Package Size** | 1.6mm x 1.2mm (4-pin VFLGA) | | **Output Type** | CMOS | | **Drive Strength** | Standard | --- ### 2. Core Features & Advantages * **MEMS Technology:** Unlike traditional quartz crystals, this uses a silicon resonator. This makes it significantly more resistant to mechanical shock and vibration. * **Automotive Grade:** It is **AEC-Q100 qualified**, meaning it is rigorously tested for the harsh environments found in automotive engine compartments or cabins. * **Low Power Consumption:** Optimized for battery-powered or energy-sensitive applications, consuming roughly 3mA during active operation. * **No Negative Resistance Issues:** Since it is an active oscillator (providing a clock signal directly) rather than a passive crystal, it eliminates the need for load capacitors and complex board tuning. --- ### 3. Pin Configuration The device uses a standard 4-pin layout for easy integration: | Pin Number | Symbol | Function | | :--- | :--- | :--- | | **1** | OE / Standby | Output Enable (High) or Low Power Mode | | **2** | GND | Ground | | **3** | OUT | Clock Output Signal | | **4** | VDD | Supply Voltage | --- ### 4. Typical Applications * **ADAS (Advanced Driver Assistance Systems):** Providing stable clocking for cameras and radar. * **Infotainment:** High-speed data processing for in-vehicle screens. * **Industrial Controls:** High-temperature environments where quartz might fail. * **Mobile Devices:** Due to the ultra-small 1612 footprint. ---
