N109228CA OIF CEI 3.1

Compliance and debug application for N1000A/86100D DCA-X and N109X DCA-M oscilloscopes

Reduce Your OIF CEI 3.1 Test Times from Hours to Minutes

Introduction

Rapidly increasing worldwide demand for video and data transfer is placing new requirements for network expansion. Designers are creating innovative network elements that allow up to 100 Gb/s, which will be delivered using four lanes of 25 to 28 Gb/s. Extra challenges abound when transferring these signals on printed circuit boards, even for short distances. The Implementation Agreement for Optical Internetworking Forum Common Electrical Interface (OIF CEI) specifies the tests and limits for these devices.

These parameters can take a full day when characterized manually, and the recalculation of factors and CTLE values adds to the time the designer spends on testing. Keysight Technologies, Inc. has created the N109228CA OIF CEI 3.1 Compliance and Debug Application for you to simplify measurement of these transmitter parameters and to obtain full results to test limits in a few minutes. This will keep you focused on getting your products to market knowing that your results are built on the heritage and consistency of Keysight measurement technology.

Easy-to-use compliance application that enables you to:

The N109228CA is an easy-to-use electrical TX test application that:

• Quickly set up equipment and make transmitter measurements

• Test your device to compliance or chosen limits

• Debug your device using custom configurations

• Remove effects of cables and fixtures

• Automatically determine optimal value of CTLE Peaking

• Generate reports to share with others

Transform Complexity into Simplicity

Satisfying the broad requirements of the OIF CEI Implementation Agreements can be very complex. The data rates for each interface have a range, rather than a fixed rate common to many standards. The test list between each OIF CEI interface varies as do the test limits; some limits depend upon previous measurements to perform the final calculations. Designers need to satisfy requirements on highly-advanced integrated circuits, host boards and modules when operating over long, medium, short and very short reaches. An extract from the 28G-SR specification table from the OIF CEI Implementation Agreement below.

Development and characterization of advanced integrated circuits is time-consuming and expensive. Designers utilize test boards similar to the one shown above to fully characterize their parts for use in their own circuits or in their customer’s circuits.

Hosts and modules have unique interface connectors and require compliance boards to enable connection to test equipment as shown here. Designers endeavor to minimize the trace lengths on the compliance boards and cable lengths.

The N109228CA software will control the N1000A/86100D DCA-X, N109X DCA-M, or PNA/TDR and readily measure your device.

By pairing your test fixture or compliance board with the N1000A/86100D, 86108B and N109228CA software, you will have the simplest and most powerful solution available to optimize your designs and offer the best products to customers. Phase trimmers and a pair of cables complement your set up for the most consistent and accurate measurements. You can easily remove the effects of cables or fixtures through intuitive Configure choices.

The N109228CA software also supports a variety of other DCA configurations (see ordering guide), including the N1094A DCA-M oscilloscope and N1076B Electrical Clock Recovery.
