MAX3784, MAX3784A

5Gbps PCB Equalizer

Please check latest availability status for a specific part variant.


The MAX3784/MAX3784A 5Gbps equalizers provide compensation for transmission-medium losses in up to 40in of FR-4. They are optimized for short-run length and balanced codes such as 8b10b, as found in multiplexed 1.25Gbps Ethernet systems and 4.25Gbps Fibre Channel.

The equalizers use differential CML data inputs and outputs. A standby mode reduces power consumption when the parts are not in use. The MAX3784/MAX3784A are available in a 4mm × 4mm, 16-pin QFN package that consumes only 185mW at +3.3V.
