400 Mbps LVDS driver — what the data rate means for cable reach
The SN65LVDS047PWRG4: At that data rate, signal integrity over a 10-meter cable depends on the cable's characteristic impedance and termination — the driver's output swing and edge rates are designed for standard LVDS (350 mV typical swing into 100 Ω), so a clean eye at the receiver requires proper termination and controlled-impedance cabling. The 4/0 driver/receiver count means this part drives four LVDS lines; it does not include a receiver, so a separate LVDS receiver (like the SN65LVDS048 or SN65LVDS049) is needed at the far end for a complete link.
3.3 V supply — compatibility and margin
It is not specified for 2.5 V logic — the supply minimum is 3 V, so a 2.5 V rail is below the operating range. For 2.5 V systems, a level translator or a different LVDS driver rated for that supply would be needed. The 3.3 V compatibility is straightforward: decouple with 0.1 µF and 10 µF ceramics close to the supply pins, and the driver is ready.
The driver's LVDS output swing and common-mode range are specified across this range, so the link budget should hold if the cable and receiver are similarly rated. No AEC-Q100 qualification is listed, so this is not an automotive-grade part for under-hood or chassis applications.
16-TSSOP package — footprint and layout
Housed in a 16-TSSOP (4.40 mm width, 0.173" pitch), the SN65LVDS047PWRG4 uses a standard surface-mount footprint.
