MAX9112EKA+T Datasheet MAX9112ESA+, MAX9110ESA+, MAX9112ESA+T | P1-P3

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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.
