For a 125 MHz SerDes reference clock, that translates to a worst-case timing error of about 400 ps — well within the jitter budget of most Gigabit Ethernet or PCIe Gen1/2 links. ## Package and footprint — 6-SMD no-lead exposed pad The pad is electrically connected to the die attach — tie it to ground or leave it floating per the datasheet recommendation; do not connect it to a supply rail. The exposed pad also provides mechanical stability under vibration. For automotive builds, ensure the solder paste coverage under the pad is at least 50 % to meet AEC-Q100 solder-joint reliability targets.","metaTitle":"DSC1123AE1-150.0000T MEMS XO, 125 MHz LVDS, AEC-Q100, Active","metaDescription":"Microchip DSC1123AE1-150.0000T: 125 MHz LVDS MEMS oscillator, AEC-Q100 rated, 2.25V–3.63V supply, ±50 ppm stability, Enable/Disable 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":"LVDS","Series":"DSC1123","Package":"Tape & Reel (TR)","Ratings":"AEC-Q100","Function":"Enable/Disable","Frequency":"125 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.276\\\" L x 0.197\\\" W (7.00mm x 5.00mm)","Voltage - Supply":"2.25V ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-20°C~70°C","Current - Supply (Max)":"32mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the DSC1123AE1-150.0000T rated for automotive applications?","answer":"Yes, it is AEC-Q100 qualified.
