10.3-Gbits/s Equalizer Resolves Signal Problems In Copper Interconnects

Best-in-class port matching (typical return loss of 24 dB) and channel-to-channel isolation (33 dB typical) is claimed for the MAX3986, a 1-Gbps-to-10.3-Gbps, quad linear equalizer for copper interconnects. Each channel in this stand-alone equalizer is capable of compensating for losses in 20-in. of FR4, with data rates up to 10.3 Gbps. Moreover, the MAX3986 is claimed as the first stand-alone equalizer that can also be used to extend the reach of limiting equalizers and decision-feedback equalizers (DFEs), commonly found integrated into serializers/deserializers (SerDes) and ASICs. The expanded linear range of the MAX3986 preserves the essential signal characteristics needed for optimum DFE performance. The MAX3986 can be used in SDR, DDR, and QDR InfiniBand; SDR and DDR IEEE-803.3ae XAUI; 8.5Gbps Fibre Channel; and serial 10.3-Gbps Ethernet applications for backplanes and copper cable assemblies. The MAX3986 operates from a 3.3-V supply. It’s packaged in a 5-mm x 7-mm 38-pin TQFN package, and is fully specified over the 0°C to +85°C temperature range. Pricing starts at $20.45 in lots of 1000.
