MAX3982 Datasheet | Maxim Integrated

.. 19-3354; Rev 0; 8/04 SFP Copper-Cable Preemphasis Driver General Description The MAX3982 is a single-channel, copper-cable preemphasis driver that operates from 1Gbps to 4.25Gbps. It provides pensation 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 pensates for up to 10in of FR4 circuit board material at 4.25Gbps. The MAX3982 also Features SFP-pliant loss-of-signal detection with selectable sensitivity and TX_DISABLE. Selectable output swing reduces EMI and power consumption. It is packaged in a 3mm x 3mm, 16-pin thin QFN and operates from 0°C to +85°C temperature range. - Drives Up to 15m with 24AWG Cable - Drives Up to 30in of FR4 - 0.25W Total Power with +3.3V Supply - Selectable 1600m VP-P or 1200m VP-P Differential Output Swing - Selectable Output Preemphasis - Fixed Input Equalization - Loss-of-Signal Detection with Selectable Sensitivity - Transmit Disable Features Applications SFP Active Copper-Cable Assemblies Backplanes 1.0625Gbps, 2.125Gbps, and 4.25Gbps Fibre Channel 1.25Gbps Ethernet 2.488Gbps STM16 Infini Band PCI Express Ordering Information PART MAX3982UTE TEMP RANGE 0°C to +85°C PINPACKAGE 16 Thin QFN PKG CODE T1633-4 Pin Configuration appears at end of data sheet.
