Key Features
- High-speed switch core with low lane-to-lane skew and preserved edge rates.
- Programmable transmitter output levels and receive equalization.
- Support for dc- and ac-coupled I/O configurations.
- On-chip termination resistors tied to user-settable supplies.
- Sign-swapping option (P/N swap) to eliminate the need for board-level crossovers.
- Serial control interface for finer resolution in setting receive equalization, transmitter preemphasis, and output levels.
Applications
The AD8155 is primarily used to support redundancy in serial link systems, including both backplane and line interface sides. It is suitable for standards such as RXAUI and can be configured for 1 + 1 or 1:1 redundancy. Additionally, it can enable module redundancy in various high-speed data transmission systems.
