PAM4 Connected Data Center
Over the past several years, PAM4 has emerged as the leading technology for implementation of a
new generation of Data Center and Wireless optical links.
Standards such as IEEE 802.3bs and 802.3cd provide a common understanding of link requirements enabling interoperability
that will drive the PAM4 communications market to scale, thereby reducing costs. Concurrently, applications such as machine
learning and 4K video apply continuous pressure on service providers to provide more, and more bandwidth. Semtech is
uniquely positioned to meet the challenges of this market by providing its customers a wide range of solutions specifically
tailored to individual application needs.

Optical Module Reference Design Kits
Improve the performance and time to market of your SFP+ design with Semtech Optical Module
Reference Design Kits.
FAST TIME-TO-MARKET
BROAD RANGE OF REFERENCE DESIGNS AVAILABLE
Semtech’s Reference Design Kits offer training through
schematics, layout files and a design guide, as well
as prompt support from our experienced applications
engineers, reducing both design costs and time to market.
This type of system is currently executed in the FTTx market,
as the ability to reuse the 10G symmetric SFP+ design to
address the 10G asymmetric market is incorporated.
Reference Design Kits are offered to cover a wide
variety of SFP+ applications, including symmetrical and
asymmetrical PON, and 10GbE SR and LR applications.
For Ethernet SFP+, designs are available for both the
traditional architecture (including a LA in the receive
chain), as well as a new LA-free architecture enabled by
Semtech’s High Gain ROSA portfolio.
