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.","metaTitle":"Microchip DSC6121HI2A-00AP XO, 19.44/25MHz, MEMS, 4-VFLGA","metaDescription":"Microchip DSC6121HI2A-00AP MEMS XO, dual output 19.44MHz & 25MHz, CMOS, ±25ppm, -40~85°C, 4-VFLGA.
