Tiny, adaptive 10.7Gbps equaliser

Supplier News

MAXIM Integrated Products, represented by Arrow Electronics , has introduced the MAX3805 10.7Gbps adaptive receive equaliser.

For 10Gbps NRZ serial data in serial communications applications, this equaliser effectively extends the usable length up to 75cm on 6-mil FR-4 or up to 8 metres on RG-188A/U type coaxial cable.

Use the MAX3805 to compensate for long 10Gbps copper links in backplane, rack-to-rack, and shelf-to-shelf interconnection applications.

The MAX3805 provides 20dB of automatically adaptive receive equalisation at 5GHz for PCB signal integrity applications from 9.95Gbps to 10.7Gbps.

The MAX3805 operates from a 3.3V supply and allows CML inputs and outputs to dc-couple to 1.8V, 2.5V, or 3.3V ICs, thereby saving off-chip component count.

This tiny 3mm x 3mm chip achieves <30ps peak-to-peak jitter performance with only 135mW of power consumption at 3.3V.

The MAX3805 operates over a temperature range of -40ºC to +85ºC. An evaluation kit is available to speed designs.
