2:1 Multiplexers and 1:2 Demultiplexers with

Loopback

General Description

Features

♦ Guaranteed 1.5GHz Operation with 250mV

The MAX9394/MAX9395 consist of a 2:1 multiplexer

and a 1:2 demultiplexer with loopback. The multiplexer

section (channel B) accepts two low-voltage differential

signaling (LVDS) inputs and generates a single LVDS

output. The demultiplexer section (channel A) accepts

a single LVDS input and generates two parallel LVDS

outputs. The MAX9394/MAX9395 feature a loopback

mode that connects the input of channel A to the output

of channel B and connects the selected input of chan-

nel B to the outputs of channel A.

♦ AC Specifications Guaranteed for 150mV

Differential Input

♦ Signal Inputs Accept Any Differential Signaling

Standard

♦ LVDS Outputs for Clock or High-Speed Data

♦ High-Level Input Fail-Safe Detection (MAX9394)

♦ Low-Level Input Fail-Safe Detection (MAX9395)

♦ 3.0V to 3.6V Supply Voltage Range

Three LVCMOS/LVTTL logic inputs control the internal

connections between inputs and outputs, one for the

multiplexer portion of channel B (BSEL), and the other

two for loopback control of channels A and B (LB_SELA

and LB_SELB). Independent enable inputs for each dif-

ferential output pair provide additional flexibility.

♦ LVCMOS/LVTTL Logic Inputs

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

MAX9394 provides high-level input fail-safe detection

for HSTL, LVDS, and other GND-referenced differential

inputs. The MAX9395 provides low-level fail-safe detec-

(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 87ps (max) skew between channels.

LVDS inputs and outputs are compatible with the

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

100Ω loads. The MAX9394/MAX9395 are offered in a

32-pin TQFP package and operate over the extended

temperature range (-40°C to +85°C).
