General Description
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
CC
-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
100
loads. 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.
