Quad LVDS Line Driver
General Description
The MAX9124 quad low-voltage differential signaling
(LVDS) line driver is ideal for applications requiring high
data rates, low power, and low noise. The MAX9124 is
guaranteed to transmit data at speeds up to 800Mbps
(400MHz) over controlled impedance media of approxi-
mately 100. The transmission media may be printed
circuit (PC) board traces, backplanes, or cables.
The MAX9124 accepts four LVTTL/LVCMOS input levels
and translates them to LVDS output signals. Moreover,
the MAX9124 is capable of setting all four outputs to a
high-impedance state through two enable inputs, EN and
EN, thus dropping the device to an ultra-low-power state
of 16mW (typ) during high impedance. The enables are
common to all four transmitters. Outputs conform to the
ANSI TIA/EIA-644 LVDS standard.
The MAX9124 operates from a single +3.3V supply and is
specified for operation from -40°C to +85°C. It is available
in 16-pin TSSOP and SO packages. Refer to the MAX9125/
MAX9126 data sheet for quad 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.
DC ELECTRICAL CHARACTERISTICS
(VCC = +3.0V to +3.6V, RL = 100±1%, TA = -40°C to +85°C. Typical values are at VCC = +3.3V, TA = +25°C, unless otherwise
noted.) (Notes 1, 2)
