Single/Dual LVDS Line Driver with Ultra-Low Differential Skew in SOT23
General Description
The MAX9110/MAX9112 single/dual low-voltage differ-
ential signaling (LVDS) transmitters are designed for
high-speed applications requiring minimum power con-
sumption, space, and noise. Both devices support
switching rates exceeding 500Mbps while operating
from a single +3.3V supply, and feature ultra-low 250ps
(max) pulse skew required for high-resolution imaging
applications, such as laser printers and digital copiers.
The MAX9110 is a single LVDS transmitter, and the
MAX9112 is a dual LVDS transmitter.
Both devices conform to the EIA/TIA-644 LVDS standard.
They accept LVTTL/CMOS inputs and translate them to
low-voltage (350mV) differential outputs, minimizing elec-
tromagnetic interference (EMI) and power dissipation.
These devices use a current-steering output stage, mini-
mizing power consumption, even at high data rates. The
MAX9110/MAX9112 are available in space-saving 8-pin
SOT23 and SO packages. Refer to the MAX9111/
MAX9113 data sheet for single/dual LVDS line receivers.

Detailed Description
The MAX9110/MAX9112 single/dual LVDS transmitters
are intended for high-speed, point-to-point, low-power
applications. These devices accept CMOS/LVTTL
inputs with data rates exceeding 500Mbps. The
MAX9110/MAX9112 reduce power consumption and
EMI by translating these signals to a differential voltage
in the 250mV to 450mV range across a 100Ωload while
drawing only 9.4mA of supply current for the dual-
channel MAX9112.
A current-steering approach induces less ground
bounce and no shoot-through current, enhancing noise
margin and system speed performance. The output

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 100Ωload.
The steady-state-voltage peak-to-peak swing is twice
the differential voltage, or 700mV (typ).
