Credo unveils the DOVE Platform, a low power PAM4 DSP family for high-speed data networks - Help Net Security

Credo announced the DOVE Platform, the second generation, low power PAM4 DSP family for high-speed data networks. The DOVE Platform includes products for 100/200/400G optical interconnects.


Credo’s proprietary PAM4 DSP architecture minimizes die size and enables mainstream silicon process technology to deliver optimal cost, power, and performance for the next generation of optical modules. Pluggable optical modules with Credo PAM4 DSPs enjoy the lowest cost-of-ownership and industry-leading performance, while using minimal power.


“Cloud operators are looking for any opportunity to gain bandwidth, reduce power, and lower cost,” said Scott Feller, Vice President of Marketing at Credo. “Credo is excited to provide a solution to enable optical transceivers that satisfies the bandwidth expansion of these next-generation datacenters.”


“100/200/400G is already responsible for over 50% of the revenue in data center networking and will be the main contributor to future growth,” said Alan Weckel, Founder and Technology Analyst at 650 Group.


“Cloud providers are looking to both deploy higher-density 100G topologies and invest in 200G and 400G deployments to keep up with demand. Power density and scalability at higher speeds are becoming increasingly essential design criteria at the switch and optical module levels,” Weckel continued.


The Credo DSP technology and equalization techniques compensate for optical impairments while maintaining low power. All Dove products share key attributes of Credo’s DSP technology including:


High-performance DSP
Continuous CTLE and DFE / FFE Rx equalization
Multi-tap Tx pre-emphasis
Industry-leading power dissipation
A full suite of test and diagnostic features
Interoperable to IEEE industry standards
Optimized and industry best compact firmware

Additionally, the Dove 200 and Dove 400 products include:


Independent PLLs per lane, enabling breakout configuration
