Credo Technology Group Holding Ltd announced two new products: Dove 800D and Dove 410D PAM4 optical DSP chips. These two chips can accelerate customer product launches and are designed to address the growing bandwidth requirements of ultra-large data centers, AI back-end clusters, and general computing networks. These integrated VCSEL-driven 800D (8x100G) and Dove 410D (4x100G) use Credo’s fourth-generation DSP technology. They are optimized, high-performance, compact products that can meet the increasingly stringent requirements of super data centers. Energy consumption requirements. The Dove 800D and 410D DSPs are tailored for multimode (MMF) applications.
Michael Girvan Lampe, Vice President of Global Sales and Marketing at Credo, said: “Artificial intelligence and machine learning have promoted the expansion of hyperscale data centers, creating an increasing demand for optical connections. Most of these optical connections require the use of 400G and 800G+ Mode short link SR4/SR8 module/active optical cable (AOC) implementation. The integrated VCSEL-driven Dove 800D and 410D optical DSP can meet the needs of this rapidly growing market and help our customers simplify PCB design while reducing the overall module group cost.”
Dove 800D is the ideal choice for the next generation of low power consumption and high performance 2x400G/1x800G OSFP/QSFP-DD800 optical modules. Dove 410D is optimized for 2x200G or 1x400G QSFP112 optical modules. Both products integrate VCSEL drivers. Each transmit and receive channel is equipped with a dedicated PLL, enabling multiple channel split modes. The use of high-performance DSP technology on the optoelectronic side combined with performance enhancement functions for photoelectric damage compensation allows the two products to achieve excellent performance while maintaining low power consumption.

Main functions and technical advantages of Dove 800D and Dove 410D
- Both the host side (electrical) and the line side (optical) are single-channel 100G PAM4 signals.
- Both the optical side and the electrical side use the fourth-generation DSP technology, which provides industry-leading high sensitivity and low bit error rate (BER) performance, providing sufficient performance margin for component changes and mass production.
- Line-side Rx supports performance enhancements tailored to address optical impairments in stressed MMF environments.
- Integrating a 100G VCSEL driver that supports programmable laser current function can optimize module layout and reduce BOM cost.
- High-performance transmitters with multi-order FIR filters allow precise optimization of the module’s electrical and optical interfaces.
- The interface on the host side supports the expansion of PCB coverage without customizing the settings of each channel.
- Independent phase-locked loops for each channel support flexible tap configurations including 2x400G, 4x200G and 8x100G.
- With a full set of test functions and loopback functions, it makes laboratory debugging and production testing easier and shortens the time to market for customers’ products.
- Low power consumption increases rack utilization and reduces thermal cooling requirements.
