Max supply current is 35 mA at the highest frequency — a 170 MHz CMOS clock into a 15 pF load draws roughly that. The 22 mA disable current means the part still sinks power when gated off; a load switch on the Vdd rail would cut it to zero for ultra-low-power sleep states. ## Sourcing reality — obsolete part No official successor part number is recorded in the lifecycle data. This means the manufacturer no longer produces it, and any available units come from surplus or broker inventory.","metaTitle":"Microchip DSC8121CL2-PROGRAMMABLE MEMS XO, 10-170 MHz","metaDescription":"Microchip DSC8121CL2-PROGRAMMABLE MEMS oscillator, XO standard type, CMOS output, 10 MHz to 170 MHz, ±25 ppm, -40°C to +105°C, 6-SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC8121","Package":"Tube","Ratings":"-","Function":"Enable/Disable","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.6V","Frequency Stability":"-","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~105°C","Current - Supply (Max)":"35mA","Available Frequency Range":"10 MHz ~ 170 MHz","Spread Spectrum Bandwidth":"-","Frequency Stability (Total)":"±25ppm","Current - Supply (Disable) (Max)":"22 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9aa5bcb33c349ee19debb7b556b38a00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC8121CL2-PROGRAMMABLE/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the DSC8121CL2-PROGRAMMABLE?","answer":"There is no official successor recorded.
