N4983A Multiplexer and Demultiplexer

N4983A-M40 44 Gb/s multiplexer

Features

Wide operating range, 2 to 44 Gb/s

Low output jitter

Low power consumption

Fast output rise/fall times

High input sensitivity

Half rate clock

Description

The N4983A-M40 is a broadband 4 to 1 multiplexer (MUX) with continuous coverage from 2 to 44 Gb/s. The four quarter-rate data inputs are single-ended and AC-coupled, while the full-rate data output is fully differential and DC-coupled. The MUX accepts a half-rate input clock and returns a quarter-rate output clock for driving other downstream circuits. A clock symmetry adjustment pin allows correction for data output duty cycle distortion. Power supply bias of negative 3.6 V is required.

Applications

The N4983A multiplexer 4:1, can be used with existing equipment to generate higher rate bit streams for use in telecom applications up to 44 Gb/s. Broadband test systems will benefit from the low power dissipation, precision connectors, and excellent output waveform characteristics. The compact size of the module allows the N4983A multiplexer 4:1, to be placed at the measurement plane, reducing or eliminating artifacts related to long cables.

N4983A-D40 44 Gb/s demultiplexer

Features

Wide operating range, 2 to 44 Gb/s

Low output jitter

Low power consumption

Fast output rise/fall times

High input sensitivity

Half rate clock

Description

The N4983A-D40 is a broadband 1 to 4 demultiplexer (DEMUX) with continuous coverage from 2.6 to 44 Gb/s. Differential data inputs are DC coupled and terminated with 50 Ω resistors to minimize reflections. The DEMUX operates from a half rate single-ended, clock input. The module features single-ended AC coupled data outputs. Power supply of negative 3.6 V is required.

Applications

The N4983A demulitplexer 1:4, can be used in telecom applications operating at transmission speeds within the demuliplexer’s 2.6 to 44 Gb/s input rate.

Broadband test systems will benefit from the low power dissipation, precision connectors, and excellent output waveform characteristics. The compact size of the module allows the N4983A demulitplexer to be placed at the measurement plane, reducing or eliminating artifacts related to long cables.
