What the ratings mean for your BOM
The DSC6021JI2A-00A2: The dual-frequency output (24 MHz and 48 MHz) lets a single oscillator serve two clock domains — a common pattern in mixed-speed designs where a microcontroller core runs at 48 MHz and a peripheral bus or USB interface at 24 MHz, saving a second oscillator footprint.
Sourcing an obsolete MEMS oscillator
For existing BOM lines that require this exact order code, supply is limited to independent-distribution surplus and broker channels. Each lot is verified for authenticity and date-code traceability before shipment; availability and pricing are confirmed at RFQ time.
