The CMOS output swings rail-to-rail into the downstream clock input. ## Power budget and thermal envelope for a dense clock tree The MEMS base resonator does not suffer the quartz cold-start drift that crystal oscillators show below 0°C. The 4-VDFN package uses a standard 4-pin footprint — pin 1 is OE (output enable), pin 2 GND, pin 3 output, pin 4 Vdd. No external load caps; the CMOS output drives up to 15 pF directly. ## Obsolete — sourcing through independent channels This part is not supported for new designs. Available through independent surplus and broker channels. Lot-specific date codes and quantities are confirmed at RFQ.","metaTitle":"Microchip DSC6021CI2A-009UT XO MEMS, 40/80MHz, Obsolete","metaDescription":"Microchip DSC6021CI2A-009UT XO MEMS oscillator, 40MHz & 80MHz CMOS outputs, 1.3mA typ, -40°C~85°C.
