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.
The MAX3784 and MAX3784A are adaptive 5 Gbps PCB equalizers that compensate for transmission‑line loss on FR‑4 backplanes up to 40 in (1 m). They use differential CML inputs and outputs, support low‑power standby mode, and are supplied in a 4 mm × 4 mm, 16‑pin QFN package.
The document details absolute maximum ratings, electrical characteristics, pin descriptions, typical operating characteristics, layout recommendations, and package information. It also includes application notes for 4.25 Gbps Fibre Channel and 4 × 1.25 Gbps Ethernet configurations.
| Supply Voltage (Vcc) | -0.5 V to +6 V |

The device operates from –0.5 V to +6 V.
It consumes 185 mW at +3.3 V in low‑power mode.
It is available in a 4 mm × 4 mm, 16‑pin QFN package.
Pulling the EN pin low puts the equalizer into low‑power standby mode.
