SUNNYVALE, Calif.--Aug. 13, 2003--Maxim Integrated Products (NASDAQ: MXIM) introduced the MAX3841, the industry's highest performance, lowest power, 12.5 Gbits/s, 2 x 2 crosspoint-switch IC. The MAX3841 is ideal for high-speed serial-data loopback, redundancy, and switching for serial OC-192 and 10GbE applications or other applications up to 12.5 Gbits/s. In addition to functioning as a 2 × 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 V, 2.5 V, or 3.3 V CML ICs. Maxim's second-generation silicon germanium (SiGe) process technology provides excellent jitter performance over competing devicesless 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 equally 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 mm × 4 mm, 24-pin thin QFN package. Prices start at $10.95 (1000-up, f.o.b. U.S.A.). An evaluation kit is available to speed designs.
