The DSC6021JI1B-01UJ: The MEMS resonator construction avoids the quartz supply-chain constraints seen in legacy crystal oscillators — no cold-start frequency drift and no mechanical shock sensitivity that can shift a crystal's fundamental mode.
CMOS output eliminates the need for external termination resistors on short traces, simplifying the layout for the dual clock fan-out to the target ICs.
The deciding factor is the output frequency pair — the DSC6021JI1B-01UJ delivers 12.288 MHz and 24.576 MHz; a different order code in the family would carry a different frequency combination.
