The LVDS output at 156.25 MHz is the reference clock for 10G Ethernet PHYs, FPGAs with gigabit transceivers, and SERDES framers. LVDS gives a 350 mV swing into a 100-Ω differential termination — low enough to keep radiated emissions under control without external filtering, and fast enough edge rate to drive a point-to-point trace up to about 12 inches on standard FR-4. The supply range is 2.25V to 3.63V — it runs directly off a 3.3V or 2.5V rail without an intermediate LDO. The 32 mA max supply current at 156.25 MHz is typical for an LVDS oscillator at this frequency; the 95 µA disable current (Standby function) lets a power-management controller shut the clock off during system sleep and keep the battery drain negligible. ## Package and temperature — board-fit checklist 6-SMD no-lead package, 3.20 mm x 2.50 mm, 0.90 mm seated height. The land pattern is the same as a standard 6-pin quartz oscillator footprint — drop-in compatible with existing board layouts that expect a 3.2 x 2.5 mm XO.","metaTitle":"DSC1103CE2-156.2500T MEMS XO 156.25 MHz LVDS - Microchip","metaDescription":"DSC1103CE2-156.2500T: Active MEMS XO, 156.25 MHz LVDS output, ±25 ppm stability, 2.25V-3.63V supply, -20°C to 70°C.","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":"DSC1103","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"156.25 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"6-SMD, No Lead","Product Status":"Active","lifecycle_stage":"eol_hot","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Voltage - Supply":"2.25V ~ 3.63V","Base Product Number":"DSC1103","Frequency Stability":"±25ppm","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)":"95µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can DSC1103CE2-156.2500T replace a standard quartz oscillator?","answer":"Yes — the 6-SMD no-lead package and pinout match the industry-standard 3.2 x 2.5 mm quartz XO footprint.
