New Credo DSPs optimized for active optical
cables and short reach tranceivers target next generation
hyperscale data centers and AI
Credo Technology Group Holding Ltd (NASDAQ: CRDO) today
introduced the new Dove 800D and 410D PAM4 DSPs ICs to accelerate
time-to-market and address the increasing bandwidth requirements of
hyperscale customers, AI backend clusters and general compute
applications. These 8x100G and 4x100G per lane devices incorporate
VCSEL drivers and fourth generation DSP technology which combined,
creates an optimized, high-performance, small footprint solution
that meets the increasingly stringent energy efficiency
requirements of hyperscalers. The Dove 800D and 410D DSPs are
tailored for multimode optical fiber (MMF) applications.

New buildouts require an increasing
number of optical fiber connections driven by applications such as
AI and machine learning. The majority of this traffic is sent over
short links using optical SR4/SR8 modules or AOCs. Dove 800D and
410D DSPs, with integrated VCSEL drivers, address this market and
enable our customers to simplify their PCB design while reducing
overall module costs. (Graphic: Business Wire)
“The newest hyperscale buildouts require an increasing number of
optical fiber connections driven by applications such as AI and
machine learning,” said Michael Girvan Lampe, Vice President of
Worldwide Sales and Marketing at Credo. “The majority of this
traffic is sent over short 400G and 800G MMF links using optical
SR4/SR8 modules or Active Optical Cables (AOCs). Dove 800D and 410D
DSPs, with integrated VCSEL drivers, address this expanding market
and enable our customers to simplify their PCB design while
reducing overall module costs.”
The Dove 800D is ideal for next-generation, low-power,
high-performance 2x400G, or 1x800G OSFP and QSFP-DD800 optical
transceivers. The Dove 410D is optimized for 2x200G or 1x400G
QSFP112 optical transceivers. Both devices include integrated Credo
VCSEL drivers. Dedicated PLLs for each transmit and receive data
lane enable a wide range of breakout applications. High-performance
optical and electrical host side DSP technology, together with
specialized performance enhancing features, compensate for optical
and electrical impairments while maintaining low power
dissipation.
Dove 800D and Dove 410D Key Features and Technical
Benefits
- 100G PAM4 on both the electrical host and optical line
side.
- Fourth generation DSPs on optical side and electrical side
deliver industry leading sensitivity and Bit Error Rate
performance, providing margin for component variation and
high-volume manufacturing.
- Line side Rx performance-enhancing features tailored to address
optical impairments in stressful MMF environment.
- Integrated 100G VCSEL drivers with programmable laser currents
to optimize module layout and reduce BOM costs.
- High-performance transmitters come with multi-tap FIR filters,
allowing precision optimization at both the module electrical
connector and optical interface.
- Host side interface supports extended PCB reach without the
need for customized per-channel settings.
- Independent phase locked loops per channel support flexible
breakout configurations including 2x400G, 4x200G and 8x100G.
- Full suite of test features and loopbacks simplifies lab bring
up and production testing to reduce time-to-market.
- Low-power dissipation enables higher rack utilization and lower
thermal cooling requirements.
