MEMS oscillator with dual-frequency output
The DSC6121HI2A-00AP: Unlike quartz-based oscillators, the MEMS resonator eliminates crystal aging drift and start-up reliability concerns tied to load-capacitance matching — the frequency is set by the silicon MEMS structure, not an external quartz blank.
Typical current draw is 3 mA maximum, making this oscillator suitable for power-sensitive channels where a quartz counterpart might draw 6–10 mA at the same frequency.
Sourcing reality for an obsolete part
Availability is through independent distribution channels; quantities are confirmed at RFQ against the specific BOM line. No pin-compatible drop-in replacement is documented from Microchip, so a board-level qualification is required for any alternative.
