50 MHz MEMS oscillator with automotive qualification
The DSC1121BI5-050.0000 is a 50 MHz XO (Standard) oscillator based on a MEMS resonator, producing a CMOS output. 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.
