Five-channel LVDS transmitter for parallel-to-serial conversion
The Texas Instruments SN75LVDS83DGGG4 is a 5-driver LVDS transmitter from the FlatLink™ series, designed to convert a 28-bit parallel data bus into four serial LVDS data streams plus a dedicated clock channel.
Supply rail and signal integrity constraints
For a 28-bit parallel bus at typical pixel clock rates, the LVDS output swing is fixed by the supply; plan for controlled-impedance traces (100 Ω differential) on the four data pairs and the clock pair. The 56-TSSOP package (6.10 mm body width) fits a standard fine-pitch TSSOP footprint, but the 0.5 mm pitch demands a clean stencil aperture for consistent solder joints.
The base product number 75LVDS83 indicates a mature family; the G4 suffix typically denotes a lead-free / RoHS-compliant finish, which matches the RoHS compliance expected for commercial electronics.
What the 5/0 driver/receiver count means for your link budget
With 5 drivers and 0 receivers, this is strictly a transmit-side device. The five outputs cover four data channels plus one clock — enough for a 28-bit parallel bus (7 bits per channel). The receiver side must be a separate LVDS deserializer such as the SN75LVDS82 or equivalent. If your design needs bidirectional LVDS or a transceiver, this part will not work.
