The DSC1121CM1-012.2880T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a 12.288 MHz CMOS output with ±50ppm frequency stability across a wide 2.25V to 3.6V supply range.
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — a compact footprint that fits tight PCB layouts without requiring via-in-pad or special fan-out.
Buyers need immediate availability to avoid production delays.
Compliance is mandatory for many designs and purchasing decisions.
Designers must ensure the oscillator meets timing accuracy requirements.
Ensures compatibility with existing power supply design.
Helps find alternatives when stock is low or for cost optimization.
Long lead times can affect project schedules and need planning.
