A typical single-output MEMS oscillator in the same package would require two separate devices to cover both frequencies. ## Sourcing an obsolete MEMS XO Microchip has classified the DSC6121CI2A-00AGT as obsolete. Each lot is verified for authenticity and traceability before shipment. Availability and lead time are quoted per RFQ. If a new design requires a dual-output MEMS oscillator, consider evaluating Microchip's current DSC61XX family offerings or a pin-compatible alternative from another MEMS oscillator vendor. The 4-VDFN (3.2 mm x 2.5 mm) footprint is common across many MEMS XO suppliers.","metaTitle":"Microchip DSC6121CI2A-00AGT MEMS XO, 25MHz & 50MHz CMOS","metaDescription":"Microchip DSC6121CI2A-00AGT MEMS XO, dual CMOS outputs 25 MHz & 50 MHz, ±25 ppm, 1.71V-3.63V, -40°C~85°C, 4-VDFN.
