MEMS resonator, programmable frequency, ±25ppm over temperature
The DSC8121CI2T: This part ships as a blank (user-programmable) device, meaning the output frequency is set during the manufacturing process per the customer's order code.
6-SMD no-lead package and board-fit notes
The 6-pad footprint is standard for this class of MEMS oscillator; the no-lead construction keeps the package height low for tight card-cage or stacked-PCB assemblies.
