The **MV26T3AG-R** is a high-performance, automotive-grade MEMS (Micro-Electro-Mechanical Systems) oscillator produced by **Microchip Technology**. It belongs to the DSC6000 family, specifically designed for applications requiring high stability and low power consumption in harsh environments. --- ### 1. Key Technical Specifications The following table outlines the core electronic characteristics of the MV26T3AG-R: | Parameter | Specification | | :--- | :--- | | **Output Frequency** | 26.0000 MHz | | **Supply Voltage (Vdd)** | 1.71V to 3.63V | | **Operating Temperature** | -40°C to +125°C (AEC-Q100 Grade 1) | | **Frequency Stability** | ±20 ppm (over temp and aging) | | **Output Type** | LVCMOS | | **Current Consumption** | ~1.3 mA (Active), 1.0 µA (Standby) | | **Package Size** | 1.6mm x 1.2mm (4-pin VFLGA) | --- ### 2. Core Electronic Components & Architecture The device is not a simple quartz crystal; it is an integrated circuit consisting of two primary dies inside a single package: #### A. MEMS Resonator Die * **Material:** High-Q silicon resonator. * **Function:** Unlike traditional quartz which vibrates mechanically, this MEMS structure is etched into silicon. It acts as the frequency reference, offering superior resistance to shock and vibration (up to 20,000G). #### B. Fractional-N PLL (Phase-Locked Loop) * **Function:** The MEMS resonator provides a base frequency, which the internal PLL synthesizes to exactly 26.0000 MHz. * **Compensation:** Includes temperature sensors and compensation circuitry to ensure the frequency remains stable despite heat fluctuations in automotive engines or industrial gear. #### C. LVCMOS Output Buffer * **Function:** Drives the 26MHz clock signal to the host microcontroller (MCU) or System-on-Chip (SoC). It is designed for low electromagnetic interference (EMI). --- ### 3. Pin Configuration The MV26T3AG-R utilizes a standard 4-pin layout for easy PCB integration: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **Standby / OE** | Enables or disables the output to save power. | | 2 | **GND** | Circuit Ground. | | 3 | **Output** | 26MHz CMOS Clock Signal. | | 4 | **Vdd** | Power Supply Input. | --- ### 4. Application Advantages 1. **Automotive Reliability:** Qualified under **AEC-Q100**, making it suitable for ADAS (Advanced Driver Assistance Systems), infotainment, and engine control units. 2. **Size Efficiency:** The 1612 package (1.6mm x 1.2mm) is significantly smaller than traditional 3225 quartz crystals, saving PCB real estate. 3. **No "Start-up" Issues:** Unlike quartz, which can be sensitive to moisture or cold starts, the MEMS architecture ensures a fast, reliable startup within milliseconds.
