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.
