At that speed, the 3.3 V LVDS swing (~350 mV differential) keeps EMI low, but the PCB trace impedance needs to be held to 100 Ω differential ±10% to avoid reflections that close the eye. The driver's output edge rates are fast enough that stub lengths on the transmission line should be kept under 0.5 inches — a common layout discipline for this data rate. The base product number 65LVDS9638 covers the family, and the DG4 suffix denotes the RoHS-compliant, lead-free finish in the 8-SOIC package.","metaTitle":"SN65LVDS9638DG4 LVDS Driver, 400 Mbps, 8-SOIC, Active","metaDescription":"Texas Instruments SN65LVDS9638DG4 dual LVDS driver, 400 Mbps data rate, 3 V to 3.6 V supply, industrial temp -40°C to 85°C, 8-SOIC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Driver","Duplex":"-","Series":"65LVDS","Package":"Tube","Protocol":"LVDS","Data Rate":"400Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65LVDS9638","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"2/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2fc8df5c44369a95af748012a35030ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65LVDS9638DG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65LVDS9638DG4 and SN65LVDS9638?","answer":"The DG4 suffix indicates a lead-free, RoHS-compliant finish on the 8-SOIC package. The base part SN65LVDS9638 without the suffix may have been offered in a tin-lead finish; electrically the two are identical in data rate, supply range, and temperature grade. For new designs the DG4 variant is the current active offering."},{"question":"Is SN65LVDS9638DG4 compatible with SN65LVDS9637?","answer":"The SN65LVDS9637 is a single-channel driver in the same 65LVDS family, while the SN65LVDS9638DG4 is a dual-channel driver. They are not pin-compatible, but they can be used on the same board if the channel count matches the application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65LVDS9638DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65LVDS9638DG4 when reusing this data.
