Detailed Description
LVDS is a signaling method intended for point-to-point
communication over a controlled-impedance medium
as defined by the ANSI TIA/EIA-644 and IEEE 1596.3
standards. LVDS uses a lower voltage swing than other
common communication standards, achieving higher
data rates with reduced power consumption while
reducing EMI and system susceptibility to noise.
The MAX9173 is a 500Mbps, four-channel LVDS receiv-
er intended for high-speed, point-to-point, low-power
applications. Each channel accepts an LVDS input and
translates it to an LVTTL/LVCMOS output. The receiver
is specified to detect differential signals as low as
100mV and as high as 1.2V within an input voltage
range of 0 to V
CC
. The 250mV to 400mV differential out-
put of an LVDS driver is nominally centered around a
1.2V offset. This offset, coupled with the receiver
s 0 to
V
CC
input voltage range, allows more than ±1V shift in
the signal (as seen by the receiver). This allows for a
difference in ground references of the transmitter and
the receiver, the common-mode effects of coupled
noise, or both.
