The LVDS differential pair keeps jitter low over board traces, which matters when the clock edge drives a SerDes PLL that multiplies up to line rate. ## Stability and supply range for industrial environments The 2.25V to 3.63V supply range lets it run from a 2.5V or 3.3V rail without an external LDO; the 32 mA max supply current is the total draw including the LVDS output stage. 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm.","metaTitle":"DSC1123BI5-156.2500 MEMS Oscillator","metaDescription":"Active XO (Standard) MEMS oscillator, 156.25 MHz LVDS output, ±10 ppm stability, -40°C to 85°C. 6-SMD package.","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":"Tube","Ratings":"-","Function":"Enable/Disable","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":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"2.25V ~ 3.63V","Base Product Number":"DSC1123","Frequency Stability":"±10ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"32mA","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"22mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8550","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32c33983bfd645bac8d0b2ac5207c872.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1123BI5-156.2500/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123BI5-156.2500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123BI5-156.2500 when reusing this data.
