Active current is 8 mA max — typical for a 49.5 MHz CMOS oscillator; the MEMS core consumes less than a quartz equivalent at the same frequency, which helps keep the thermal budget tight in a sealed enclosure. ## 4-VDFN package and board layout Housed in a 4-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits compact PCB layouts where board space is at a premium — typical for ADAS cameras, radar modules, or infotainment head units.","metaTitle":"DSC1001DL5-049.5000T – 49.5 MHz MEMS XO, CMOS, AEC-Q100","metaDescription":"Microchip DSC1001DL5-049.5000T: 49.5 MHz MEMS oscillator, CMOS output, ±10 ppm stability, AEC-Q100, -40°C to 105°C, 1.7-3.6V supply, standby function.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1001","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Standby (Power Down)","Frequency":"49.5 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-VDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"1.7V ~ 3.6V","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C ~ 105°C","Current - Supply (Max)":"8mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"15µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e16d8c0e20d671fdec1bc4732fc9156.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1001DL5-049.5000T AEC-Q100 qualified?","answer":"Yes, it carries AEC-Q100 qualification, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up.
