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 multi-
plexed 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.
