The DSC1121AL5-050.0000 is a 50 MHz XO (Standard) oscillator built on a MEMS resonator, outputting CMOS levels across a 2.25V to 3.6V supply range.
Housed in a 6-VDFN with exposed pad, 7.00mm x 5.00mm body, 0.90mm seated height — the land pattern matches standard 7x5 mm MEMS oscillator footprints, so a board laid out for a common SiTime or Abracon MEMS part accepts this drop-in.
Design engineers need to verify if the 50 MHz output and ±10ppm stability meet their timing requirements.
Ensuring compatibility with the system's power rail (2.25V-3.6V) is critical for proper operation.
Sourcing buyers and layout engineers need to confirm the 6-VDFN footprint and enable/disable function pin mapping.
Transactional buyers must know availability and delivery time to avoid production delays.
Brokers and maintenance technicians need to know if this part can directly replace other MEMS oscillators without PCB respin.
Long-term buyers must assure it is active and not near end-of-life for sustained procurement.
