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.

Single/Dual LVDS Line Drivers with Ultra-Low Pulse Skew in SOT23 Board Layout For LVDS applications, a four-layer PC board that provides separate power, ground, LVDS signals, and input signals is recommended. Isolate the input and LVDS signals from each other to prevent coupling. Separate the input and LVDS signal planes with the power and ground planes for best results. Typical Operating Circuit +3.3V +3.
