The Keysight Technologies N4983A-M40 broadband 4 to 1 multiplexer operates from 2 to 44 Gb/s. The four quarter-rate inputs are single-ended and AC-coupled, while the full-rate data output is fully differential and DC-coupled. The N4983A multiplexer accepts a half-rate input clock and returns a quarter-rate output clock for driving other circuits. A clock crossing point adjustment pin allows correction for duty cycle distortion. Power supply bias of negative 3.6 V is required.
The Keysight Technologies N4983A-D40 broadband 1 to 4 demultiplexer operates from 2.6 to 44 Gb/s. Differential data inputs are DC-coupled and terminated to ground with 50 ohm resistors to minimize reflections. The single-ended, half-rate clock input is AC-coupled and operates with low input power. The N4983A demultiplexer features single-ended AC-coupled outputs with ECL compatible signal levels.
