Dual-frequency MEMS oscillator — what the specs mean for fit
The DSC6121CI2A-0090T: The ±25 ppm frequency stability covers temperature, supply, and aging — adequate for general-purpose clocking in MCU, FPGA, or interface PHY applications where a quartz crystal's tighter tolerance is not required.
Obsolete — sourcing path for the BOM line
For existing BOM positions, the part is available through independent surplus and broker channels. Quantities are lot-specific; availability and pricing are confirmed at RFQ time.
