Quad Bus LVDS Driver with Flow-Through Pinout
General Description
The MAX9129 is a quad bus low-voltage differential sig-
naling (BLVDS) driver with flow-through pinout. This
device is designed to drive a heavily loaded multipoint
bus with controlled transition times (1ns 0% to 100%
minimum) for reduced reflections. The MAX9129
accepts four LVTTL/LVCMOS input levels and trans-
lates them to output levels of 250mV to 450mV (stan-
dard LVDS levels) into a 27Ωload at speeds up to
200Mbps (100MHz).
The power-on reset ensures that all four outputs are
disabled and high impedance during power up and
power down. The outputs can be set to high imped-
ance by two enable inputs, EN and EN, thus dropping
the device to a low-power state of 11mW. The enables
are common to all four drivers. The flow-through pinout
simplifies PC board layout and reduces crosstalk by
keeping the LVTTL/LVCMOS inputs and BLVDS outputs
separated.
The MAX9129 operates from a single +3.3V supply and
is specified for operation from -40°C to +85°C. It is
available in 16-pin QFN and TSSOP packages. Refer to
the MAX9121 data sheet for a quad LVDS line receiver
with flow-through pinout.

Detailed Description
The MAX9129 is a 200Mbps quad differential BLVDS
driver designed for multipoint, heavily loaded backplane
applications. This device accepts LVTTL/LVCMOS input
levels and translates them to output levels of 250mV to
450mV into a 27Ωload. The flow-through pinout simpli-
fies board layout and reduces the potential for crosstalk
between single-ended inputs and differential outputs.
Transition times are designed to reduce reflections, yet
enable high data rates. The MAX9129 can be used in
conjunction with standard quad LVDS receivers, such
as the MAX9121, to implement full-duplex multipoint
buses more efficiently than with transceivers.
Effect of Capacitive Loading
The characteristic impedance of a differential PC board
trace is uniformly reduced when equal capacitive loads
are attached at equal intervals (provided the transition
time of the signal being driven on the trace is longer
than the delay between loads). This kind of loading is
typical of multipoint buses where cards are attached at
1in or 0.8in intervals along the length of a backplane.
