The DSC1121CL2-040.0000 is a 40 MHz XO (Standard) MEMS oscillator from Microchip's DSC1121 series, delivering a CMOS output 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 max, the DSC1121CL2-040.0000 sits flat on the pad with no exposed leads to tombstone — the MEMS die is encapsulated, so MSL is typically Level 1, but confirm the reel label before the oven.
Yes — the DSC1121CL2-040.0000 is a MEMS-based XO with a CMOS output, so it directly replaces a 40 MHz quartz oscillator in the same 6-SMD footprint without changing the PCB layout or supply decoupling. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which is why this part carries AEC-Q100 qualification.
Yes — the DSC1121CL2-040.0000 carries an AEC-Q100 rating, meaning it has passed the automotive-grade temperature cycling, ESD, and reliability stress tests. It is suitable for under-hood and chassis-domain ECUs where the ambient temperature reaches 105°C.
