The MAX9152 2 x 2 crosspoint switch is designed for
applications requiring high speed, low power, and low-
noise signal distribution. This device includes two
LVDS/LVPECL inputs, two LVDS outputs, and two logic
inputs that set the internal connections between differ-
ential inputs and outputs.
The MAX9152 can be programmed to connect any
input to either or both outputs, allowing it to be used in
the following configurations: 2
mux, 1:2 demux, 1:2 splitter, or dual repeater. This flexi-
bility makes the MAX9152 ideal for protection switching
in fault-tolerant systems, loopback switching for diag-
nostics, fanout buffering for clock/data distribution, and
signal regeneration for communication over extended
distances.
Ultra-low 120ps
communications in high-speed links that are highly sen-
sitive to timing error, especially those incorporating
clock-and-data recovery, or serializers and deserializ-
ers. The high-speed switching performance guarantees
an 800Mbps data rate and less than 50ps (max) skew
between channels.
LVDS inputs and outputs are compatible with the
TIA/EIA-644 LVDS standard. The LVDS inputs are
designed to also accept LVPECL signals directly, and
PECL signals with an attenuation network. The LVDS
outputs are designed to drive 75Ω or 100Ω loads, and
feature a selectable differential output resistance to
minimize reflections.
The MAX9152 is available in 16-pin TSSOP and SO
packages, and consumes only 109mW while operating
from a single +3.3V supply over the -40°C to +85°C
temperature range.
