Single/Dual LVDS Line Drivers with
Ultra-Low Pulse 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 100Ω load 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
