MAX3841ETG+

The MAX3841ETG+ is a low power, 12.5Gbps CML 2 × 2 crosspoint switch in 24 pin TQFN package. The 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. Unused outputs can be powered down individually to conserve power. In addition to functioning as 2 × 2 switch, the MAX3841 can be configured as 2:1 multiplexer, 1:2 buffer or dual 1:1 buffer. It is used in OC-192, 10GbE switch/line cards, OC-192, 10GbE optical modules, system redundancy/self test and lock fan-out.
