That data rate suits it for high-speed serial links like clock distribution, backplane interconnects, or camera-sensor interfaces where common-mode noise rejection matters. Packaged in an 8-VSSOP (also listed as 8-TSSOP or 8-MSOP, 0.118-inch body width), the footprint is compact enough for dense PCB layouts but still hand-solderable with a fine tip. The 2/0 driver/receiver count tells you this is a pure driver — no receiver on-chip, so pair it with an LVDS receiver like the SN65LVDS9637 for a complete link. ## 400 Mbps — what that means for signal integrity At 400 Mbps, the fundamental frequency is 200 MHz, and the 3rd harmonic hits 600 MHz. That means PCB trace length should be kept under about 6 inches on standard FR-4 before you need to worry about reflections. The LVDS differential swing is typically 350 mV, so the receiver threshold is tight — keep the differential impedance at 100 Ω and route the pair tightly coupled.","metaTitle":"SN65LVDS9638DGKRG4 LVDS Driver, 400 Mbps, 8-VSSOP","metaDescription":"TI SN65LVDS9638DGKRG4 dual LVDS driver, 400 Mbps per channel, 3V–3.6V supply, -40°C to 85°C, 8-VSSOP.","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":"Tape & Reel (TR)","Protocol":"LVDS","Data Rate":"400Mbps","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65LVDS9638","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-VSSOP","Number of Drivers/Receivers":"2/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2fc8df5c44369a95af748012a35030ec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to SN65LVDS9638DGKRG4?","answer":"Within the same 65LVDS family, the SN65LVDS9638D is the same dual driver in an 8-SOIC package — same pinout, same 400 Mbps rating, but a larger body.
