Whatever the budget, high-performance cars are high-precision engineered solutions using state-of-the-art mechanical technology. The same is true of routing bleeding-edge 112 Gbps PAM4 signals on a PCB or in a system. State-of-the-art IP, SerDes, semiconductor and interconnect technology are required.
Samtec is a world leader in high-performance interconnects. Alphawave IP technology connects the digital world faster. Their combined solutions enable data to travel faster, more reliably and with higher performance at lower power in any high-speed, high-performance application.
Samtec 112 Gbps PAM4 Product Portfolio
Routing electrons or signal paths from chip-to-chip, board-to-board or rack-to-rack requires many design flexibility. Fortunately, Samtec offers a comprehensive portfolio of front-panel, mid-board and backplane interconnects capable of support 112 Gbps PAM4 data rates.
AcceleRate® HP: AcceleRate HP high-performance arrays and cable systems, on 0.635 mm pitch, feature open-pin-field design maximizing grounding and routing flexibility. Data Rate compatible with PCIe®5.0 and 100 GbE. Low-profile 5mm and up to 10 mm stack heights.
ExaMAX® Backplane Cable System: ExaMAX® backplane cable systems leverage Samtec Flyover® technology for improved bandwidth and reach in backplane applications. Direct solder attach to contacts optimizes the signal path, further enhancing performance.
Flyover® QSFP Cable System: Samtec’s Flyover QSFP Systems (FQSFP-D8 for 800 G) provide improved signal integrity and architectural flexibility by routing critical high-speed signals through low-loss, ultra low skew twinax cable, instead of through expensive, lossy PCBs.
NovaRay®: NovaRay arrays and cable systems combine extreme density and performance in a small form-factor. The fully shielded differential pair design and two reliable points of contact contribute to the industry-leading 4.0 Tbps aggregate data rate.
NovaRay I/O Front Panel Cable System: NovaRay I/O offers the highest aggregate data rate on the market, 3,584 Gbps PAM4, with a high-density cable-to-cable bulkhead panel connection. Passive electric external cables prevent a large thermal load at the panel with heat sinks, saving valuable panel space.
Alpahwave IP AlphaCORE LR MSS
The AlphaCORE Long-Reach (LR) Multi-Standard-Serdes (MSS) IP is a high-performance, low-power, DSP-based PHY. It is a highly configurable IP that supports all leading edge NRZ and PAM data center standards from 1 Gbps to 112 Gbps, supporting diverse protocols such as PCIe 5.0 and 100 GbE.
The brilliance of the AlphaCORE LR MSS is in its register configurable DSP architecture. The AlphaCORE leverages high-performance A/D converters to digitize incoming data over copper or fiber. The AlphaCORE Master Controller uses complex signal processing techniques to recover the signal, while optimizing both power and latency.
Linking 112 Gbps PAM4 IP and Interconnect
Designing 112 Gbps PAM4 channel solutions presents many technical design challenges. Real-world signal paths require the balanced interplay of silicon, SerDes PCB traces and interconnect solutions. The combination of Alphawave IP SerDes and Samtec interconnect solutions ease design efforts in many applications
Engineers need to learn how these associative technology complement each other. Fortunately, technical experts from Alphawave IP and Samtec will cover this in an upcoming webinar. 112 Gbps PAM4 Implementation: Real World Case Studies occurs Thursday, June 2, 2022 at 11:00 AM ET/8:00 AM PT.
Additionally, six real world signal paths will be presented. Two will be board-to-board. Two signals are mid-board to front panel. The final two signal paths are mid-board to backplane. All are at 112 Gbps PAM4 data rates.
