Quad LVDS Line Driver with
Flow-Through Pinout
General Description
The MAX9123 quad low-voltage differential signaling
(LVDS) differential line driver is ideal for applications
requiring high data rates, low power, and low noise. The
MAX9123 is guaranteed to transmit data at speeds up to
800Mbps (400MHz) over controlled impedance media of
approximately 100Ω. The transmission media may be
printed circuit (PC) board traces, backplanes, or cables.
The MAX9123 accepts four LVTTL/LVCMOS input levels
and translates them to LVDS output signals. Moreover,
the MAX9123 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. Flow-through pinout
simplifies PC board layout and reduces crosstalk by sep-
arating the LVTTL/LVCMOS inputs and LVDS outputs.
The MAX9123 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 MAX9121/
MAX9122* data sheet for quad LVDS line receivers with
integrated termination and flow-through pinout.
