Keysight has selected Credo's retimer/gearbox devices for its Layer 1-3 800GE network device and Ethernet protocol test solutions for network infrastructure.
Keysight provides 800GE Layer 1-3 test coverage with an extensive set of use cases and break-out Ethernet port speeds from 800GE to 100GE, while leading the industry with the highest port density per rackmount unit in test solutions.
Credo said its devices were for two strategic test capabilities: First, the chip-to-module, high performance SERDES with 112 Gb/s electrical lanes with PAM4 signaling for 1x800GE and related slower port speed support. Most importantly, the ability to provide auto negotiation and link training (AN/LT) – which are needed for support of passive and active direct attached copper (DAC) cabling required for switch and server interconnections within equipment racks that are deployed in high volume within data centers.
Keysight Technologies introduced an 800G compliance test solution for validating 112 gigabit per second (Gbps) serial data center interfaces. The new 112 Gbps conformance test solution leverages Keysight’s M8040A 64 GBaud high performance bit error ratio tester (BERT) with a N1060A Digital Communication Analyzer (DCA) for receiver testing and Keysight’s Infiniium UXR-Series real-time oscilloscope for transmitter testing. Interfaces capable of...
Credo Technology Group introduced its new Sparrow 800G gearbox and Heron 1.6T retimer/gearbox devices.The new Sparrow and Heron devices are built around Credo’s core low-power, high-performance DSP technology to offer improved line card functionality. The devices deliver the increased bandwidth, improved power, and cost efficiency required to support the large, growing data infrastructure market.“Credo’s core value in developing products is to deliver...
Keysight Technologies expanded its portfolio of 800G test solutions for the optical transceiver ecosystem. The latest addition to Keysight’s existing portfolio of 800G test solutions are new design and validation solutions that support multimode interfaces, which are critical for an energy efficient data center infrastructure. The 800G multimode test solutions uniquely support high-speed data interconnect speeds of up to 100 Gbps.In December 2020,...
Credo introduced its Black Hawk (CRT55321), a PAM4 retimer and gearbox for providing guaranteed, end-to-end signal integrity in backplane, front panel and copper applications. The new device, which leverages the company’s unique PAM4 DSP architecture, is a 32-lane device that supports 16 lanes on the host side and 16 lanes on the line side. The extended reach performance provides robust signal integrity for PAM4 across the most difficult channels,...
