The 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 V

differential inputs.

Ultra-low 82ps

(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

100Ω loads. The MAX9390/MAX9391 are offered in a

32-pin TQFP package and operate over the extended

temperature range (-40°C to +85°C).

Also refer to the MAX9392/MAX9393 with flow-through

pinout.
