Keysight Technologies announced a collaboration with Kandou Bus to advance high-speed digital signaling applications

Keysight Technologies announced a collaboration with Kandou Bus to advance high-speed digital signaling applications using Keysight's test solutions for characterizing Chord™ signaling transmitter and receiver designs.

Data centers are experiencing a surge in computing, storage and performance demand.  This is due to data intensive applications driven by 5G technology such as virtual reality (VR), Internet of Things (IoT) applications, artificial intelligence (AI), and the roll-out of autonomous vehicles. In its report Data Age 2025, IDC predicts that by 2025 this digital transformation will result in more than 175 zettabytes of data generated around the world per year. As a result, data centers are evolving from using 100 Gigabit Ethernet (100GE) data speeds to 400GE and beyond. This requires moving from Non-Return to Zero ("NRZ") to new modulation technologies such as four-level Pulse Amplitude Modulation (PAM4), or alternatively the use of Chord signaling. Chord signaling is a multi-wire signaling approach that is a generalization of differential signaling.

Keysight's transmitter test solutions leverage the multi-channel acquisition system of the N1000A DCA-X wide-bandwidth oscilloscope and the company's recently introduced N1010100A FlexDCA R&D software to quickly decode and analyze Chord signaling applications that utilize groups of correlated signals such as CNRZ-5 (5 bits on 6 correlated wires) and ENRZ (3 bits on 4 correlated wires). Together with Keysight's M8100 Series Arbitrary Waveform Generator (AWG), users can easily generate the multi-wire encoded waveforms used in receiver test applications
  

Kandou is an interface technology company that specializes in the design, license and implementation of multi-wire link solutions, offers an innovative multi-wire signaling technology. Kandou's Chord™ signaling designed for reducing power consumption and improving the performance of semiconductors used in routers, servers, mobile phones and satellites. It can also be used to support USB4 high-speed digital connections as well as 400GE applications.
