6.25Gbps, 1.8V PC Board Equalizer

General Description

Features

The MAX3785 6.25Gbps equalizer operates from a sin-

gle 1.8V supply and compensates for transmission-

medium losses encountered with FR4 transmission

lines. Optimized for low-voltage, high-density, DC-cou-

pled interconnections between the line card and switch

card, the MAX3785 enables a system upgrade path

while maintaining a legacy rate of 2.5Gbps to

3.125Gbps. Roughly the size of two 0603 passive com-

ponents, the MAX3785 easily provides placement and

routing flexibility.

ꢀ Single 1.8V Supply

ꢀ Very Low Power, 60mW

ꢀ Spans 30in with FR4 at 6.25Gbps

ꢀ Operates from 1.0Gbps to 6.4Gbps

ꢀ Coding Independent, 8b/10b or Scrambled

ꢀ DC-Coupled CML Inputs and Outputs

ꢀ Small 1.5mm × 1.5mm Footprint

Ordering Information

The MAX3785 is comprised of an equalizer, limiting

amplifier, and output driver. For data rates of 3.2Gbps

and lower, the MAX3785 equalizes signals for spans up

to 40in of FR4 board material. For data rates up to

6.25Gbps, the MAX3785 compensates for 30in of FR4

board material. The MAX3785 is coding independent,

functioning equally well for 8b/10b or scrambled signals.

Pin Configuration

The MAX3785 features DC-coupled current-mode logic

(CML) data inputs and outputs. It is packaged in a tiny

1.5mm ✕ 1.5mm chip-scale package (USCP™) and a

6-pin TDFN package.
