The DSC1121CI2-050.0000T: Its wide supply voltage range of 2.25V to 3.6V lets it run from common 2.5V or 3.3V rails without a separate LDO, and the Enable/Disable function allows the output to be tri-stated for system power management.
Housed in a 6-SMD no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, this is a standard MEMS oscillator footprint — the same land pattern as many quartz oscillators in the same size, so the board layout stays compatible.
Sourcing buyers need immediate stock availability to avoid production delays.
Engineers need to verify electrical specifications for design validation.
Automotive applications require qualified components for reliability.
Buyers need to plan procurement and avoid supply chain issues.
If the part is unavailable, designers need a drop-in replacement to maintain schedule.
Designers must ensure voltage compatibility; this part requires 2.25-3.6V.
