Maximum current draw is 3 mA typical — low enough for battery-powered or thermally constrained designs where every milliampere counts. For a 49.152 MHz clock, ±25 ppm translates to roughly ±1.2 kHz of absolute jitter budget — sufficient for most Ethernet PHY and audio codec reference clocks, though a tighter ±10 ppm part would be needed for precision video timing. ## Obsolete — sourcing reality and what replaces it A board-level evaluation of any replacement is advised before committing the BOM line.","metaTitle":"DSC6121CE2A-0082 Microchip MEMS XO, 45.1584/49.152 MHz, CMOS","metaDescription":"Microchip DSC6121CE2A-0082 MEMS XO, dual output 45.1584 & 49.152 MHz, CMOS, ±25 ppm, 1.71-3.63V, 4-VDFN.
