 Details
The MAX3982 is a single-channel, copper-cable preem-
phasis driver that operates from 1Gbps to 4.25Gbps. It
provides compensation for copper links, such as
4.25Gbps Fibre Channel, allowing spans of up to 15m
with 24AWG. The cable driver provides four selectable
preemphasis levels. The input compensates for up to
10in of FR4 circuit board material at 4.25Gbps.
The MAX3982 also features SFP-compliant loss-of-signal
detection with selectable sensitivity and TX_DISABLE.
Selectable output swing reduces EMI and power con-
sumption. It is packaged in a 3mm x 3mm, 16-pin thin
QFN and operates from 0°C to +85°C temperature range.
19-3354; Rev 2; 2/06
