Typical supply current is 3 mA max — low enough for battery-powered edge nodes, and the 4-VFLGA package dissipates that without any thermal concern even in still air. ## Industrial temperature range and CMOS interface The CMOS output swings rail-to-rail and drives standard digital loads directly — no external termination or bias resistors are required, simplifying the layout. ## Obsolete — sourcing through independent channels No pin-compatible direct replacement exists from Microchip; a board spin may be required for a new-design alternative.","metaTitle":"Microchip DSC6121HI2A-00APT MEMS XO, 19.44/25MHz, CMOS","metaDescription":"Microchip DSC6121HI2A-00APT MEMS XO, dual-output 19.44MHz & 25MHz, CMOS, ±25ppm, 1.71-3.63V, -40~85°C.
