General Description
The MAX9125/MAX9126 quad low-voltage differential
signaling (LVDS) line receivers are ideal for applica-
tions requiring high data rates, low power, and reduced
noise. The MAX9125/MAX9126 are guaranteed to
receive data at speeds up to 500Mbps (250MHz) over
controlled-impedance media of approximately 100
.
The transmission media may be printed circuit (PC)
board traces or cables.
The MAX9125/MAX9126 accept four LVDS differential
inputs and translate them to 3.3V CMOS outputs. The
MAX9126 features integrated parallel termination resis-
tors (nominally 115
), which eliminate the requirement
for four discrete termination resistors and reduce stub
length. The MAX9125 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 differ-
ences 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 control the high-impedance output and
are common to all four receivers. Inputs conform to the
ANSI TIA/EIA-644 LVDS standard. The MAX9125/
MAX9126 operate from a single +3.3V supply, are
specified for operation from -40°C to +85°C, and are
available in 16-pin TSSOP and SO packages. Refer to
the MAX9124 data sheet for a quad LVDS line driver.
