It is part of Microchip's DSC1121 series and comes in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm. The Enable/Disable function lets you gate the output without cycling the supply — useful for power sequencing or test modes where the clock line must be tri-stated. AEC-Q100 qualification means the part has passed automotive-grade reliability stress tests: it is production-validated for automotive Tier-1 applications that require PPAP documentation and traceability. ## Supply voltage and current draw Operates from 2.25V to 3.6V, so it can run on a 2.5V or 3.3V rail without an extra regulator. The max supply current is 35 mA when active and 22 mA when disabled — the disable current is still present because the internal MEMS resonator and PLL remain powered. ## Frequency stability and mounting Frequency stability is ±50 ppm over the full temperature range — tight enough for most microcontroller and FPGA clock trees that do not require a TCXO or OCXO. Surface-mount package with a seated height of 0.90 mm max. The exposed pad on the 6-SMD package should be soldered to a ground plane for thermal management; the pad also provides a low-inductance return path for the high-frequency output.","metaTitle":"DSC1121AM1-050.0000 MEMS Oscillator","metaDescription":"Active Microchip DSC1121AM1-050.0000 XO (Standard) MEMS oscillator, 50 MHz CMOS output, AEC-Q100 qualified, -55°C to 125°C.
