The MAX9178 quad low-voltage differential signaling
(LVDS) line driver with high-ESD tolerance is ideal for
applications requiring high data rates and low power
with reduced noise. The MAX9178 is guaranteed to
transmit data at speeds up to 400Mbps (200MHz) over
controlled impedance of media of approximately 100Ω.
The transmission media can be printed circuit (PC)
board traces, backplanes, or cables.
The MAX9178 accepts four LVTTL/LVCMOS inputs and
translates them to LVDS output signals. All inputs toler-
ate overshoot of V
EN and EN inputs are ANDed together and control the
high-impedance outputs. When the device is disabled,
power drops to ultra-low 12.6mW (typ). Outputs con-
form to the ANSI TIA/EIA-644 LVDS standard.
The MAX9178 operates from a single +3.3V supply,
and is available in a 16-pin TSSOP and 16-pin thin QFN
package with exposed pad. The MAX9178 is specified
for operation from -40°C to +85°C.
