Scalable Low-Voltage Signaling (SLVS)

SLVS is a chip-to-chip signaling standard designed for maximum performance with minimum power consumption, inheriting low noise susceptibility from LVDS. The standard features a scaled-down 
400 mV signal swing, versus the 700 mV swing of LVDS, and includes a ground reference. GPIO and HSIO banks support the SLVS I/O standards, but an external resistor is required for transmitter mode. For more information, see Implementing Emulated Standards for Outputs.
