General Description
The MAX9121/MAX9122 quad low-voltage differential sig-
naling (LVDS) differential line receivers are ideal for appli-
cations requiring high data rates, low power, and low
noise. The MAX9121/MAX9122 are guaranteed to receive
data at speeds up to 500Mbps (250MHz) over controlled-
impedance media of approximately 100
. The transmis-
sion media may be printed circuit (PC) board traces or
cables.
The MAX9121/MAX9122 accept four LVDS differential
inputs and translate them to LVCMOS outputs. The
MAX9122 features integrated parallel termination resis-
tors (nominally 107
), which eliminate the requirement
for four discrete termination resistors and reduce stub
lengths. The MAX9121 inputs are high impedance and
require an external termination resistor when used in a
point-to-point connection.
The devices support a wide common-mode input range of
0.05V to 2.35V, allowing for ground potential differences
and common-mode noise between the driver and the
receiver. A fail-safe feature sets the output high when the
inputs are open, or when the inputs are undriven and
shorted or parallel terminated. The EN and EN inputs con-
trol the high-impedance output. The enables are common
to all four receivers. Inputs conform to the ANSI TIA/EIA-
644 LVDS standard. Flow-through pinout simplifies PC
board layout and reduces crosstalk by separating the
LVDS inputs and LVCMOS outputs. The MAX9121/
MAX9122 operate from a single +3.3V supply, and are
specified for operation from -40°C to +85°C. These
devices are available in 16-pin TSSOP and SO packages.
Refer to the MAX9123 data sheet for a quad LVDS line dri-
ver with flow-through pinout.
