Frequency stability is held to ±50 ppm across the 0°C~70°C commercial temperature range, which suits indoor, office, and appliance environments where the ambient stays conditioned. The MEMS resonator core gives this oscillator better shock and vibration tolerance than a quartz fundamental — relevant if the board sees handling in assembly or moderate mechanical stress in service. ## Obsolete — sourcing reality for this BOM line Microchip lists the DSC1018BC1-100.0000 as Obsolete. Existing BOM lines can be filled through independent surplus channels; quantities are lot-specific and confirmed at RFQ. No official successor or pin-compatible replacement is recorded from Microchip for this exact order code. ## Standby function and disable current A Standby (Power Down) function disables the output and drops the supply current to 1 µA max — useful for power-gated clock trees where the oscillator is stopped during sleep modes. Active supply current is 5 mA typ at 100 MHz, a low figure for a MEMS oscillator at this frequency, keeping the thermal contribution to the board minimal. ## Package and board integration note Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. Surface-mount mounting — the pad layout follows the standard 4-pin oscillator pattern; no special via-in-pad or thermal relief beyond typical SMD practice.","metaTitle":"DSC1018BC1-100.0000 Microchip 100 MHz MEMS XO, CMOS","metaDescription":"DSC1018BC1-100.0000 is a 100 MHz MEMS XO with CMOS output, 1.8V supply, ±50 ppm stability, 0°C~70°C.","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":"DSC1018","Package":"Tube","Ratings":"-","Function":"Standby (Power Down)","Frequency":"100 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"1.8V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°C","Current - Supply (Max)":"5mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0291cd7293e82768a7c2198660ff52d5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1018BC1-100.0000 obsolete?","answer":"Yes.
