PAM4 OEM Long-Distance Optical Transceiver for IoT Applications
The Marvell Ara PAM4 DSP is a next generation solution for GenAI and cloud datacenter interconnects utilizing pluggable transceivers. Marvell leads the pluggable module ecosystem with low-power, high-performance silicon for AI, cloud, enterprise and 5G. The Broadcom® BCM87840 is the industry's highest-performance and lowest-power single-chip 400GbE PAM-4 PHY transceiver capable of driving four lanes of 106-Gb/s PAM-4 at 53 Gbaud, while supporting DR4, FR4, LR4, and QSFP112 optical links. The BCM87840 leverages Broadcom's market-leading 7-nm PAM-4. For 400G optical transceivers, both OSFP and QSFP-DD use the 8x50G/PAM4 electrical signal for the host interface, which means they both employ PAM4 modulation. A key new modulation scheme, PAM4, was introduced around 2017 and enabled the big jump from 100G to 400G. When it comes to enabling 400G and higher Ethernet speeds, a four-level pulse amplitude modulation or PAM4 multilevel signaling is needed as opposed to the non-return-to-zero (NRZ) modulation.
