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.
