16nm Nx56G PAM-4 PHY Highlights
- Long-reach performance capable of compensating for >30dB of insertion loss at 56 Gb/s
- Enables low power Nx56G PAM-4 PHYs with high performance DSP-based equalization to address both copper and optical cabling systems including multi-mode fiber (MMF) and single-mode fiber (SMF)
- IEEE 802.3bs compliant FEC capability
- Proprietary Super-FEC (S-FEC) with 9.4dB coding gain, extended burst error correction capability, and low latency for extended reach
- Protocol agnostic supporting various interconnect interfaces:
- IEEE 802.3bs/cd 50/100/200/400GbE for backplane & copper cabling
- CDAUI-8 chip-to-module & chip-to-chip
- OIF 56G-LR-PAM-4 for PCB & cabled backplane
- System side interface options and compatibility to support both legacy 28Gbps NRZ I/Os and next generation 56Gbps PAM-4 I/Os on standard product Switch chips and ASICs
- Guaranteed interoperability with Broadcom’s standard product Switch chips and ASICs
“Doubling the per lane data rate from 28 Gb/s to 56 Gb/s is critical to meeting the rapidly increasing bandwidth requirements in today’s cloud computing and hyper-scale data center environments,” said
“PAM-4 is fast becoming a standard for 50-400G networking and data center connections,” said
