Current draw is 3 mA typical per output — combined, the two active outputs pull about 6 mA from the supply. That low consumption makes this oscillator a fit for power-sensitive designs where a can-style quartz oscillator would burn twice the budget. ## Obsolete — sourcing reality for the DSC6121CI2A-00ES That means the manufacturer no longer produces this exact order code — no last-time-buy window remains open, and no official successor part number has been assigned. For BOM lines that still call out this oscillator, supply runs through independent distribution and surplus channels.","metaTitle":"DSC6121CI2A-00ES MEMS XO, 48MHz & 50MHz, CMOS, ±25ppm","metaDescription":"Microchip DSC6121CI2A-00ES MEMS XO, dual output 48MHz & 50MHz, CMOS, ±25ppm, 1.71V-3.63V, -40°C to 85°C, 4-VDFN.
