12.5Gbps CML 2 × 2 Crosspoint Switch
General Description
The MAX3841 is a low-power, 12.5Gbps 2 × 2 crosspoint switch IC for high-speed serial data loopback, redundancy, and switching applications. The MAX3841 current-mode logic (CML) inputs and outputs have isolated VCC connections to enable DC-coupled interfaces to 1.8V, 2.5V, or 3.3V CML ICs. Fully differential signal paths and Maxim’s second-generation SiGe technology provide optimum signal integrity, minimizing jitter, crosstalk, and signal skew. The MAX3841 is ideal for serial OC-192 and 10GbE optical module, line card, switch fabric, and similar applications. The MAX3841 has 150mVP-P minimum differential input sensitivity, and 500mVP-P nominal differential output swing.
