stage presents a symmetrical, high-impedance output,
reducing differential reflection and timing distortion. The
driver outputs are short circuit current limited and enter a
high-impedance state when the device is not powered.
LVDS Operation
The LVDS interface standard is a signaling method
intended for point-to-point communication over a con-
trolled impedance medium as defined by the EIA/TIA-
644 LVDS standard. The LVDS standard uses a lower
voltage swing than other common communication stan-
dards, achieving higher data rates with reduced power
consumption while reducing EMI emissions and system
susceptibility to noise.
LVDS transmitters such as the MAX9110/MAX9112
convert CMOS/LVTTL signals to low-voltage differential
signals at rates in excess of 500Mbps. The MAX9110/
MAX9112 current-steering architecture requires a resis-
tive load to terminate the signal and complete the trans-
mission loop. Because the device switches the direc-
tion of current flow and not voltage levels, the actual
output voltage swing is determined by the value of the
termination resistor at the input of an LVDS receiver.
Logic states are determined by the direction of current
flow through the termination resistor. With a typical
3.5mA output current, the MAX9110/MAX9112 produce
an output voltage of 350mV when driving a 100
load.
The steady-state-voltage peak-to-peak swing is twice
the differential voltage, or 700mV (typ).

0.1μF and 0.001μF capacitors in parallel, as close to the
device as possible, with the smaller valued capacitor the
closest. For additional supply bypassing, place a 10μF
tantalum or ceramic capacitor at the point where power
enters the circuit board.
