Anything-to-LVDS Dual 2 x 2

Crosspoint Switches

General Description

Features

The MAX9392/MAX9393 dual 2 x 2 crosspoint switches

perform high-speed, low-power, and low-noise signal

distribution. The MAX9392/MAX9393 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.

♦ 1.5GHz Operation with 250mV Differential Output

♦ 2ps

(max) Random Jitter

RMS

♦ AC Specifications Guaranteed for 150mV

Differential Input

♦ Signal Inputs Accept Any Differential Signaling

Standard

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 MAX9392/MAX9393 ideal for protection

switching in fault-tolerant systems, loopback switching for

diagnostics, fanout buffering for clock/data distribution,

and signal regeneration.

♦ LVDS Outputs for Clock or High-Speed Data

♦ High-Level Input Fail-Safe Detection (MAX9392)

♦ Low-Level Input Fail-Safe Detection (MAX9393)

♦ 3.0V to 3.6V Supply Voltage Range

♦ LVCMOS/LVTTL Logic Inputs Control Signal

Routing

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

MAX9392 provides high-level input fail-safe detection

for LVDS, HSTL, and other GND-referenced differential

inputs. The MAX9393 provides low-level input fail-safe

(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 67ps (max) skew between channels.

Pin Configurations

TOP VIEW

LVDS inputs and outputs are compatible with the

TIA/EIA-644 LVDS standard. The LVDS outputs drive

100Ω loads. The MAX9392/MAX9393 are offered in

a 32-pin TQFP package and operate over the extended

temperature range (-40°C to +85°C).
