Detailed Description
LVDS is a signaling method for point-to-point data com-
munication over a controlled-impedance medium as
defined by the ANSI/TIA/EIA-644 and IEEE 1596.3 stan-
dards. LVDS uses a lower voltage swing than other
common communication standards, achieving higher
data rates with reduced power consumption, while
reducing EMI emissions and system susceptibility to
noise.
The MAX9153/MAX9154 are 800Mbps, 10-port
repeaters for high-speed, point-to-point, low-power
applications. The MAX9153 accepts an LVDS input and
has a fail-safe input circuit. The MAX9154 accepts an
LVPECL input. Both devices repeat the input at 10 LVDS
outputs. The devices detect differential signals as low
as 50mV and as high as 1.2V within the 0 to 2.4V input
voltage range as specified in the LVDS standards.
The MAX9153/MAX9154 outputs use a current-steering
configuration to generate a 2.5mA to 4.5mA output cur-
rent. This current-steering approach induces less
ground bounce and no shoot-through current, enhanc-
ing noise margin and system speed performance. The
outputs are short-circuit current limited and are high
