Sunnyvale, Calif. - Maxim Integrated Products has introduced the MAX3841, the industry's highest-performance, lowest-power, 12.5-Gbit/second, 2 x 2 crosspoint-switch IC.
The MAX3841 is ideal for high-speed serial-data loopback, redundancy and switching for serial OC-192 and 10-Gigabit Ethernet applications or other applications up to 12.5 Gbits/s.
In addition to functioning as a 2 x 2 switch, this device can be configured as a 2:1 multiplexer, 1:2 buffer or dual 1:1 buffer.
The MAX3841 current-mode logic (CML) inputs and outputs have isolated Vcc connections to enable dc-coupled interfaces to 1.8-volt, 2.5-V or 3.3-V CML ICs.
Maxim's second-generation SiGe technology provides excellent jitter performance over competing devices-less than 10 ps peak-to-peak deterministic jitter and less than 0.7-ps peak-to-peak random jitter. In addition, the low channel-to-channel skew (<12 ps) and low propagation delay (100 ps) are impressive.
The MAX3841 has a differential input sensitivity of 150-mV peak to peak (min) and a nominal differential output swing of 500 mV peak to peak. Unused outputs can be powered down individually to conserve power; the MAX3841 consumes only 215 mW with both outputs enabled. This device is available in a 4 x 4-mm, 24-pin thin QFN package. Prices start at $10.95 in quantities of 1,000 or more.
An evaluation kit is available to speed designs.
