Having both on one die eliminates a second oscillator and its associated PCB routing. Microchip has marked this part Obsolete. The date-code and lot traceability are verified before shipment; the laser-etched marking on the VDFN package is the primary authenticity check against re-marked stock. ## Supply and temperature — wide margin for mixed-voltage designs This is useful when the oscillator must straddle a voltage-domain boundary — e.g., feeding a 1.8 V FPGA bank and a 3.3 V video serializer from the same device. The CMOS output drives standard logic inputs directly; no external termination or level translation is needed for sub-100 MHz clock distribution.","metaTitle":"Microchip DSC6122CI2A-00AVT MEMS XO, 74.1758/74.25MHz","metaDescription":"Microchip DSC6122CI2A-00AVT MEMS oscillator, dual-output 74.1758MHz & 74.25MHz, CMOS, ±25ppm, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.90mm)","Output":"CMOS","Series":"DSC61XX","Package":"Tape & Reel (TR)","Function":"-","Base Resonator":"MEMS","Package / Case":"4-VDFN","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"1.71V ~ 3.63V","Frequency Stability":"±25ppm","Frequency - Output 1":"74.1758MHz, 74.25MHz","Frequency - Output 2":"-","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C ~ 85°C","Current - Supply (Max)":"3mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1228b1baf388c49094d52b76abcfca61.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to DSC6122CI2A-00AVT?","answer":"No official pin-compatible successor or second-source is recorded for this specific dual-frequency variant.
