Anything-to-LVDS Dual 2 x 2 Crosspoint Switches
General DescriptionThe MAX9390/MAX9391 dual 2 x 2 crosspoint switches
perform high-speed, low-power, and low-noise signal
distribution. The MAX9390/MAX9391 multiplex one of two
differential input pairs to either or both low-voltage differ-
ential signaling (LVDS) outputs for each channel.
Independent enable inputs turn on or turn off each differ-
ential output pair.
Four LVCMOS/LVTTL logic inputs (two per channel) con-
trol the internal connections between inputs and outputs.
This flexibility allows for the following configurations: 2 x 2
crosspoint switch, 2:1 mux, 1:2 splitter, or dual repeater.
This makes the MAX9390/MAX9391 ideal for protection
switching in fault-tolerant systems, loopback switching for
diagnostics, fanout buffering for clock/data distribution,
and signal regeneration.
Fail-safe circuitry forces the outputs to a differential low
condition for undriven inputs or when the common-
mode voltage exceeds the specified range. The
MAX9390 provides high-level input fail-safe detection
for LVDS, HSTL, and other GND-referenced differential
inputs. The MAX9391 provides low-level input fail-safe
detection for LVPECL, CML, and other VCC-referenced
differential inputs.
Ultra-low 82ps(P-P)(max) pseudorandom bit sequence
(PRBS) jitter ensures reliable communications in high-
speed links that are highly sensitive to timing error,
especially those incorporating clock-and-data recovery,
or serializers and deserializers. The high-speed switch-
ing performance guarantees 1.5GHz operation and less
than 65ps (max) skew between channels.
LVDS inputs and outputs are compatible with the
TIA/EIA-644 LVDS standard. The LVDS outputs drive
100Ωloads. The MAX9390/MAX9391 are offered in a
32-pin TQFP and 5mm x 5mm thin QFN package with
exposed paddle and operate over the extended tem-
perature range (-40°C to +85°C).
Also refer to the MAX9392/MAX9393 with flow-through
pinout.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
