The BCM858345 is an advanced transceiver PHY that combines 800G (4:4) PAM-4 capability with an integrated Vertical-Cavity Surface-Emitting Laser (VCSEL) driver, suitable for next-generation high-speed data applications. This sophisticated technology enables efficient transmission of optical data at blazing speeds, fulfilling the needs of data-intensive environments such as data centers and telecommunication networks.
The BCM858345 leverages PAM-4 modulation, which allows for the doubling of data rates compared to NRZ encoding without additional bandwidth consumption. This capacity triples throughput for each lane, making it a staple in achieving higher data center efficiencies and computational workloads. The integrated VCSEL driver further optimizes this IP for optical implementations, offering a streamlined solution that enhances performance by reducing the component count and associated power and space requirements.
Broadcom’s commitment to robust design is evident in this optimized PHY, which includes advanced features for signal enhancement, error correction, and power management. These capabilities ensure high reliability and performance in demanding applications, delivering superior resilience against signal degradation over long distances.
