Credo Breaks Through the 50Gb/s NRZ Serial Data Rate Barrier

Hong Kong and Milpitas, CA., - April 12, 2014-Credo Semiconductor, a global innovation leader in SerDes technology, today announced the industry's first SerDes transceiver that can deliver speeds up to 55Gb/s NRZ signaling.  The SerDes (Serializer-Deserializer) was developed for the next generation 40G/100G/400G data center and enterprise networking applications. 

The unique 40nm CMOS design of the Credo SerDes features low jitter, low power, and low latency, as well as advanced TX pre-emphasis equalization, RX CTLE (continuous time linear equalization) and DFE (decision feedback equalization).  The SerDes has been tested at 50Gb/s across a test channel with more than 30dB loss at Nyquist frequency, clearly demonstrating that NRZ signaling can be extended well beyond today’s 28Gbps solutions.

“Credo has achieved an industry-first speed breakthrough that will enable innovative applications ranging from “100Gb/s to 400Gb/s” for the data center and enterprise networking markets,” said Bill Brennan, CEO of Credo Semiconductor.   "Credo's advanced SerDes technologies prove the feasibility of extending NRZ signaling, even at data rates up to 56Gb/s per lane, which is currently under consideration by OIF CEI-56G study group and IEEE 400G study group for next generation board level chip-to-chip interconnections.  Credo has quickly established a leadership position in SerDes data rates, and we will add to our position by delivering solutions with compelling power and loss handling in advanced geometries (28nm & 16nmFF+) in 2014.”

Credo Semiconductor will offer a private demonstration to potential business partners. Companies interested in learning more about Credo Semiconductor’s current silicon, as well as future developments should contact
