Description
The SHF 604 A is a 2:1 Multiplexer operating at data rates up to 80 Gbps for use in broadband test
setups and telecom transmission systems. Two single ended serial data streams of up to 40 Gbps areaccepted by the multiplexer and converted into one differential data signal of up to 80 Gbps. A single
ended clock signal with a frequency half of the output data rate drives the SHF 604 A.
For data regeneration purposes all input data signals are re-sampled to mitigate any signal impairments
resulting e.g. from long cables. Therefore, it becomes possible to place the MUX very close to the DUT.
All RF in- and output ports are AC-coupled and internally terminated with 50 Ohm to GND. Unused in- oroutput ports should be terminated with 50 Ohm.

Features

Broadband operation up to 80 Gbps
Differential data output, 2.8 V differential output swing (1.4 V in single-ended operation)
Single ended clock and data inputs
Output Level Control (remote by software)

Applications
100, 200 and 400 Gbps system evaluation & development
Telecom transmission
Broadband test and measurement equipment

Options
Option Case:MUX module, power supplies, heat sink and 1.85 mm panel adaptors
are housed in a small benchtop case.

Module Variants
In addition to the MUX itself, the power supplies, USB cable and heat sink are complementary parts ofeach delivery. It is recommended to use the MUX only with the delivered power supply module. The heatsink can be removed by the customer. In this case it is required to provide other cooling measures toensure that the maximum case temperature specified on page 6 will not be exceeded.

SHF 604 AWith Option Case the SHF 604 A MUX module, the power supplies, heat sink and the Mini-SMP to 1.85
mm panel adaptors are housed in a small benchtop case that can be easily embedded in the customer’s
test environment.

Ease of Use
The easy to use software package, the SHF 600 Series Control, is the most convenient way to control theoutput amplitude of the MUX.

The measurements below had been performed using a SHF 12104 A Bit Pattern Generator (PRBS 2 -1)
and a Tektronix DSA 8300 Digital Serial Analyzer (DSA) with Phase Reference Module (82A04B-60G) and
70 GHz Sampling Module (80E11). The output of the MUX module had been connected directly to the DCA
input with a 10 dB attenuator.
