The AD8158 is a 6.5 Gbps Quad Buffer Mux/Demux with 2:1 mux/1:2 demux functionality and CML inputs that supports dc to 6.5 Gbps NRZ data. The device features programmable input equalization, programmable output pre-emphasis, programmable output levels with squelch and disable, and 50 Ω on-chip termination. The AD8158 is suitable for low cost redundancy switch, SONET OC48/SDH16 and lower data rate, XAUI/GbE/FC/Infiniband over backplane OIF CEI 6.25 Gb applications.
The AD8158 is an asynchronous, protocol‑agnostic quad‑lane 2:1 switch with a total of 12 differential CML inputs and 12 differential CML outputs. Each lane offers programmable receive equalization, output pre‑emphasis, output level control, and loss‑of‑signal detection, supporting NRZ signaling up to 6.5 Gbps per lane. The device features low latency, low power consumption (≈2 W), and a balanced architecture that provides minimal lane‑to‑lane skew.
Typical applications include redundancy switching on backplanes and line‑interface sides of serial links, port‑monitoring for test equipment, and high‑speed serial link testing. Control can be performed via external toggle pins or through on‑chip registers accessed via an I²C interface.
