No official successor order code is recorded in the lifecycle data. Available through independent surplus and broker channels. Quantities are lot-specific; current pricing and lead time are confirmed at RFQ.","metaTitle":"DSC6121CI2A-00AR MEMS XO, 24MHz & 48MHz, CMOS, 4-VDFN","metaDescription":"Microchip DSC6121CI2A-00AR MEMS XO, dual output 24MHz & 48MHz, CMOS, ±25ppm, -40°C~85°C, 4-VDFN.
