Supply voltage spans 2.25V to 3.6V, allowing it to run from a 2.5V or 3.3V rail without an external LDO. ## Frequency stability and package constraints The 6-SMD, no-lead package measures 5.00mm x 3.20mm with a seated height of 0.90mm, a common footprint shared with many 5.0x3.2 mm oscillators. ## Active production — sourcing to order Product status is Active. The DSC1121 family is a current-generation MEMS oscillator line from Microchip; no pin-compatible successor has been announced. Supplied in tube. The base product number is DSC1121; this specific variant with ±10 ppm stability and AEC-Q100 grade is the BI5 ordering code. Quoted to order against BOM quantity — confirm the reel or tube quantity at RFQ.","metaTitle":"DSC1121BI5-050.0000 50 MHz MEMS XO CMOS AEC-Q100","metaDescription":"DSC1121BI5-050.0000 — 50 MHz, CMOS output, ±10 ppm stability, 2.25-3.6 V supply, -40 to 85 °C.
