Clock and Data Recovery: Ultra-Low Power, High-Performance

Semtech’s ultra-low power, high-performance reference-free clock and data recovery (CDR) product line is anchored around our ClearEdge® CDRs for NRZ (non-return-to-zero) applications at 10Gbps, 16Gbps and 100Gbps, and our Tri-Edge™ CDRs for PAM4 applications at 200Gbps and 400Gbps. Based on our reference-free CDR architecture our ClearEdge and Tri-Edge products provide multi-lane signal conditioners with best in class sensitivity, output jitter and jitter tolerance, that can also be monolithically integrated with laser drivers and transimpedance amplifiers (TIAs) to provide compact, high-performance solutions.

ClearEdge® CDR Platform for NRZ Signal Processing

Semtech’s ClearEdge CDRs deliver the lowest power, smallest footprint solutions for optical modules including:

• QSFP28
• CFP4
• XFP
• Retimed SFP+
• Other 25G and 100G modules and Active Optical Cables (AOCs)

Semtech’s ClearEdge CDRs are the world’s most widely selected optical transceiver CDRs for use in 10G and 100G data center applications.

Tri-Edge™ CDR Platform for PAM4 Signal Processing

Building on the success of Semtech’s ClearEdge NRZ-based CDR platform technology, Tri-Edge is a CDR platform optimized for PAM4 optical interconnect in next-generation 200G and 400G data center module and AOC applications. The SR Tri-Edge PAM4 CDR chipset enables industry leading power with reduced latency and low cost for multi-mode fiber links of up to 100-meters. The Tri-Edge LR platform enables 200G and 400G single mode fiber solutions up to 10km. Both the Tri-Edge SR and LR product lines are compatible with the Open Eye MSA specifications for SR and LR links.

Semtech is leading the way to enable analog PAM4-based solutions in the data center market and creating a complete analog PAM4 ecosystem with the Open Eye MSA.

Semtech’s Tri-Edge PAM4 CDRs offer the lowest power, lowest cost solution for optical modules including:

• DSFP
• QSFP56
• QSFP-DD
• OSFP
• SFP56
• SFP-DD
• 50G AOCs
• 100G AOCs
• 200G AOCs
• 400G AOCs
